Tripping electricity can be a nuisance especially if you cannot figure out the source of the problem. In such a situation the frustration of repeat breaker trips can leave you low moods. You may be confused as to whether the wiring is a problem or a particular gadget is causing it. This is one of the most common electrical faults that users experience.

In spite of the temporary unpleasant effect of a tripping circuit breaker, it is a good thing that the power actually trips. Circuit breaker trips are a good sign that your electrical system is in a safe state. The breaker works to protect your electric gadgets and prevent damage, overheating, and fires. This is why the power trips whenever there is overload or possible danger.

However, if you have power trips you still need to have a solution to resolve the issue and continue with life so to speak.

Electricians who repair electrical trips will often look at three main aspects of the system.

Overloaded Circuit

The current in an electric system flows to meet the demands or the load in current use. If the current flow is too much, more than what the system can handle it becomes dangerous. This is known as an overloaded circuit. Wires can get too hot and melt, fires can start, and damage to gadgets can happen. Therefore, a safety device that monitors the amount of current is necessary.

This is where the circuit breaker comes into play. A circuit breaker is a pair of thermostat and switch. This safety device induces a power trip to cut off power supply when the current flow is higher than the rating of the system.

So, if you have main switch tripping issues you may also need to look at the overall load.

Short Circuit

A short circuit is an abnormal connection between two nodes of an electric circuit intended to be at different voltages. When that happens, electricity leaks, looking for a path of lower resistance. Another common reference that electricians make relating to a short circuit is a situation where a live wire contacts a neutral wire.

This compromises the resistance of the system, and the result is more current flows in the system than that which is safe. Breakers pick the rise, and induce a trip.

A short circuit is dangerous as the alternative path of low resistance that the current may flow can include people or anything with low resistance.

Ground Fault

A ground fault is a type of fault in which the unintentional pathway of the straying electrical current flows directly to the earth.

Residential electrical work is done on houses and complexes in relation to installation, repairs and maintenance. A home or domestic electrician does work such as to fit electric systems, and to maintain them, and to inspect.  Home electricians are the ones to call for repair of house electrical systems as well as resolving electric appliance issues.

Such electrical job needs the electrician to inspect a system or an appliance and find the source of the issue. In some cases, the electric appliance could be the issue. Yet in other cases, there might be need to repair a faulty wiring system.

Companies that offer electrical services for houses often send out a number of workers to different homes at once. Therefore, a home electrician may be put in charge of many electricians to work under him or her.

Repair tripping electricity

Update electric systems to be in line with changes in national regulations.

Home electric scope includes interpreting technical drawings and electrical wiring diagrams.

As shown earlier, home electric scope covers items like to inspect and repair electric appliances.

Additionally, the repair of switches, lights, and wall sockets is also work that an electrician can perform in the home space.

Any other electrical maintenance work and repairs.

Furthermore, electricians working in homes repair distribution boards (BD boards), replace circuit breakers, and attend to power trips.

When it is necessary to do, a certificate of compliance may be issues for home electrical work done.

Remodelling contractors will often need electricians to rewire lines to suit the new changes.

Lights, both inside and outside, and boundary wall lights form part of the electrical scope at home.

Professional AC repairers know a lot about the main parts of an air conditioner. This info is more useful on repairs than ac installations. If your air conditioner is no longer performing well, it could be a fault on one of these ac replacement parts. The basic parts of an ac unit are: –

The refrigerant

Compressor

Condenser Coil

Expansion Valve

Evaporator Coil

In this case, we focus on a split ac unit only. The split aircon unit is the most common type of aircons in South Africa. Additionally, it is easier to understand the link between ac replacements parts on a split system. Other ac unit types will also have these typical ac parts, but will vary in arrangement and other support structures. Ducts for instance, are common components of central air conditioning system.

The components of an ac unit in a split unit are in two main sections. First, the outdoor ac unit parts and then the indoor ac unit parts.

The indoor parts of an air conditioner.

First, the evaporator. This unit enables the liquid refrigerant (coolant) to turn into a gas. As air from the room passes this unit, the refrigerant absorbs the heat very fast. The liquid coolant then turns into gas. The gas coolant is then sent to the compressor. Meanwhile, the room gets cooler as more heat from room temperature air is being used up to heat the coolant and boil it into gas.

Second, the refrigerant (coolant) is a special fluid that moves round the system in a loop. It is responsible for absorbing heat from room air and to release it outside. The coolant has good quality in terms of the ease to convert from liquid to gas and back again. Therefore, it is a chosen medium of heat transfer in air conditioning units. Heat transfer is the main activity in the air conditioning and refrigeration services.

Filters – the indoor unit also contains filters and the display functions of an air conditioner are on the indoor unit. The unit is usually a wall mount or a ceiling mount position. Filters help trap dust and therefore are vital for making sure that the air is fresh. Furthermore, dust hinders the spread of cool air, and end up compromising the cooling ability of the unit. Additionally, filters also aid in keeping the ac drain clean, a blockage in the drain will strain the compressor. Consequently, this will cause the pump to over work and run down.

Let us look at the outdoor parts of an air conditioner.

AC Compressor

The compressor receives the coolant from the evaporator in gas state, and turns it into liquid by pressing it. As the pump presses the gas, its turns to liquid and is sent to the condenser. The liquid coolant is then sent to the condenser coil.

Condenser Coil – By the time the refrigerant gets to the condenser coil, it is already hot and at high pressure. As it passes through the condenser coil, it releases heat and becomes cooler. The cool liquid is then taken back to the evaporator where it absorbs more room temperature air and the cycle continues.

Expansion Valve

This ac unit part used to be in the indoor, but now commonly found outdoor. Although the coolant leaves the condenser in its liquid state and cooler state, it is still too hot to enter the evaporator coils. The expansion valve is a main part of the air conditioner for this work, and it further lowers the heat levels of the refrigerant to levels that the evaporator can accept.

These three parts, together with the electrical components supplying the compressor, are the main parts of an air conditioner on the outside.

It is not that hard to get the best electrical installers in Gauteng, if you follow a few simple steps. The benefits of taking your time in checking and verifying your options are too many to ignore.

Surveying and mapping is a field that brings together the gathering of land size information and the modelling of such information. Land Surveyors use the name geodesy for base surveys for large-scale mapping. Geodesy is the name of the science of taking measurements for large areas of land. This skill takes into account the actual shape of the earth. It does not assume a perfect sphere, but consider the real level changes of the earth.

In order to collect land information for 3D models and maps, surveying has to take place, using accurate references. In fact, project plans, designs, and models are only useful if there is a common reference. Users of surveying and mapping services require one of two things. Either to show land sizes, levels, conditions and other real world land aspects in the form of a virtual image or the opposite.

A virtual show of land can be in the form of a map, a 3D model or other computer aided designs (CAD).

Surveying makes use of start-of-the-art tools and machinery to come up with reliable and accurate sizes for mapping. Additionally, various geographic information systems can be made from land surveying data.

Aerial surveying is one of the methods in use to make maps to support reliable project plans and designs. Maps and surveys have wide use in industry. To do away with tedious work, aerial maps are in use. Mapping agencies take photos during flights. The flights are in strips which are pre determined.

Surveying and mapping play a fundamental role to all civil engineering and roadway design work.

In construction and land development, the surveying function is to transfer design elements from CAD to the actual ground. Surveyors in engineering projects take both horizontal and vertical measurements in order to locate and mark up where objects should lie. Additionally, surveyors survey land to come up with contours to show how elevation and distance relate to each other on a piece of land.

An additional part of surveying measurement and mapping is in mining engineering. Surveying gives miners the direction of exploration for instance, as well measuring the volume of product. Normally, there is need for a monthly survey to give the amount of mineral produce. Surveying the mineral dumps will give accurate volume of mineral produce for the month.

Furthermore, building renovations that require excavation, makes use of maps showing sub surface utilities.

Geodetic surveying – surveyors use geodetic science to come up with maps of large areas, which takes into account the real shape of the globe. The geodetic surveys do not assume a theoretical perfect sphere shape of the earth, but rather follows all variations of hills and valleys.

Engineering, Mining and Town Planning Project Control

Geographic information systems, CAD drawings and modelling are products of surveying that are in use to manage construction projects, land use projects and other natural resource management tasks. Such data is useful in the management of engineering, mining, and land use fields.

Mapping

Accurate maps showing boundaries, oceans, natural and man-made resources with a base reference are tools for national land administration.

A Land surveyor is a pro in accurate sizing for maps, marking out points and corners in construction. Surveyors also mark out corners for legal boundaries. Surveyors make use of high accuracy machines in their work. Common tools in use in the land surveying field include total stations, GPS, levels as well as drones.

Land surveyors deal with sizes of land, land surface patterns, and parts of buildings in various forms.

In the civil and built engineering, land surveyors direct and lead site works in terms of managing positions and levels of parts of the building.

Every aspect of size on a drawing or design should appear on the ground as it is on the design. Therefore, surveyors manage the transfer of info from the drawing to the ground.

Examples of surveyor’s roles in engineering projects include setting out surveys and as-built surveys. Such projects can be bridge construction, railways, roads, dams, power stations, shopping malls and more.

Land survey consultants often appoint land surveyors to specific projects in order for daily works to be done effectively.

Property boundary division is a job that cannot be done by anyone except a land surveyor who is in the register of surveyor general to perform such work.

First, the surveyors take accurate sizing on the property for sub-divisions or corner marking. Additionally, surveyors also combine two or more pieces of  land into one legal document. Then the surveyor uses the data to plot a diagram and lodge it at the Surveyor General’s Office for approval. This diagram, a surveyor general diagram (SG diagram), is the one to register and attach onto title deeds.

When you a buy a piece of land, the rights of ownership is shown in the form of a title deed. A surveyor prepares such a diagram to shows legal corners of a piece of land. On that diagram, data such as the shape of the land, the outline corners and length of the sides are shown.

Additionally, surveyors also play a role in country boundaries disputes as they measure and record such data.  Moreover, in national and regional mapping projects land surveyors are at the start of the process.

Surveyor engineer works mainly on civil engineering projects to review plans and identify potential problems on designs. Additionally, engineering surveyors guide site works in accurately setting out positions of structures. Various engineering disciplines depend on engineering surveys the physical marking of design drawings on the ground. Take for instance the case of an engineer who design a civil structure to sustain a particular minimum load. Such a design will consider has to be accurate in terms of distance of positions of supports and footings. This ensures that building maintains strength and integrity. This is where a surveyor engineer comes in.

Furthermore, a site surveyor will not only ensure that the horizontal position is accurate, but will manage alignment and proper elevations as the site works continue.

Typically, projects that needs engineering surveying services are in construction and building. Examples are projects like roads, freeways, railways, bridges, tunnels and other large structures.

The engineering surveyor’s work begins in the feasibility study phase to furnish designers with spatial data for designs. The work continues as project is under construction, up to the final as built surveys when project completes. A surveying engineer may also be called a construction surveyor.

Surveyors take precise measurements of land and collects data on elevations and positions. Special attention is given to natural as well as man-made features, their sizes and shape. This information provides engineers the specific detail they require in order to draw up designs. Architects, civil engineers and town planners require such information, usually presented in the form of a topographical maps.

A designer needs specific land information such as natural terrain for the design of drainage systems, roads and other community services.

Surveyors spend a lot of time working outdoors on various sites taking measurements. Therefore, a surveyor should be a person who enjoys working outdoors.

Surveying is a discipline required on site by various other fields, so a surveyor should be able to work well and communicate with others.

Site surveyors analyse design drawings and interpret them so as to calculate coordinates and elevations for setting out and site markings. Therefore, a good command of Maths is necessary. Additionally, sound maths background helps surveyors to work independently. Surveyors make decisions and judgements that has a systematic approach, usually with a maths root.

Like any engineering profession, a good understanding of computer aided design software is necessary. Engineering software enables services faster delivery and more professional data formats.

A survey engineer may work as a freelance, getting hired as and when the need arises, or can get full time employment. Employment prospects are found in areas such as engineering consulting companies and surveying companies. A wider opportunity also is in mining companies, government departments, and other construction firms.

Planning and surveying activities have a common overlap in the overall regional and national development projects.

Areas of interest include transportation systems, rural development and community projects, recreation facilities development and allocation. Other areas are environmental planning and conservation, and urban development.

As planners allocate land for various purposes, they need surveying function to assist and guide the process of subdivisions applications, land ownership and dimensional records as well as the overall topography of a region of interest.

Surveying of land is the beginning of town planning process. The surveyor collets land and surface data in form of sizes and elevations and prepares maps according to the desired purpose. Maps showing the terrain of parcels of land and maps for towns and municipalities are a product of survey activities.

A topographic surveyor is responsible for such surveys that produce maps of terrains, contours, natural and man-made features. An engineering surveyor can also do such surveys and produce similar maps. However, engineering surveyors tend to focus more on the construction phase of the work. On the other hand, a cadastral surveyor will focus more on the demarcation of property and land ownership, as well as the legal aspect of land ownership.

There is also underground services management considerations.

The surveyor will revise maps as new developments come in. Additionally, town planners and surveyors work to guide developmental activities to maintain safety in execution. For instance, projects that require massive excavation should consider existing underground utilities. The surveyor guides such an operation to ensure no live services are damaged.

In summary, mapping of resources, grading, drainage and utilities management is a product of surveyor – planner relationship.

Underground utilities determination is a very important aspect of developments in already built-up areas.

Proper town planning calls for an interdisciplinary approach in handling common resources and utilities, and goes further than the surveyor – planner relationship.

Planners need develop systems that require accuracy of land information, a role which surveyors fill in. The surveyor and planner work together in developing three-dimensional modelling and proposals.

Recent developments in technology in laser technology helps surveying and planning processes in terms of spatial project management.

A paving contractor prepares ground and pave surfaces with bricks, concrete, stones, blocks and other desired material. Paving companies work on domestic and commercial property to meet the needs of either human traffic or vehicle traffic. It is therefore clear that home pavement projects have short cycles. Some contractors choose to focus on only one type, either residential pavement or industrial pavement.

As a home improvement contractor, a paving company looks at small projects such as walkways paving, driveways paving, patios and other spaces of interest like pool surrounds.

In commercial projects, paving companies work on roads and surfaces that support vehicle movement. In other cases, such pavement will bear load for heavy trucks loading and off-loading bays. Other projects prepare concrete floors for storage of equipment and other material.

Apart from installing pavement, there is also the maintenance and repair of pavement to look at.

Builders may also be able to do some paving work, especially pavement around the house. However, it is available to choose a company that specializes in paving because their rates are usually lower. This is because paving contractors are faster and more effective. They have more experience which helps them to complete tasks faster thereby cutting costs.

A good maintenance contractor is one able to advise client on the cost implications of design options or renovation proposals. Similarly, a paving company should spend time with the client, discussing and verifying options available, with costing. Such a consultation process should aim at making the most from the available budget. Therefore, getting several pavement installation quotations in detail will aid a client to decide on how to select the best contractor.

Here are a few examples of what a paving company deals with:

Laying and paving driveways, walkways, and footpaths.

Paving patios, pool surrounds and washing areas.

Surfacing and resurfacing courtyards and car parking lots.

Paving garages.

Roads and commercial surfaces.

A paving walkway can make a huge difference in terms of creating a welcoming and warm reception to your visitors.
