Residential Services

Solar Installations

We offer complete Solar power system installations for private residential buildings, public buildings as well as business, commercial and other industrial applications.

We have a variety of off-grid and grid-tied solar power systems that are designed to save you money on your electricity bill and protect you against load shedding and power failures.


Electrical Certificate of Compliance (COC)

We issue Electrical Certificate of Compliance as a guarantee that any electrical work has been carried out to South African safety standards. This document verifies that the electrical installations such as the plugs, lights, distribution board, geyser and wiring in a home or business comply with the legislated requirements as detailed in the Occupational Health and Safety Act.

By law, all electrical installations and repairs must comply with the code of practice SANS 10142 for the wiring of your property.


Childproof Electrical Outlets

Childproof electrical outlets appear identical to standard wall outlets, they are anything but, they are different in a number of ways. These specialised outlets have spring-loaded receptacle cover plates to protect electrical contacts. These outlets prevent children from inserting objects when unequal pressure is applied to the receptacle’s contact points.

Commercial Services


PLC, VSD and Motor Control

We specialize in the installation and maintenance of all types of PLC, VSD and Motor control applications.

Diagnosis and Repair

No matter what type of shop or business you have, new or existing, and regardless of what electrical equipment your business utilizes, you can count on Electotech 24 hours a day, seven days a week to handle even the most complex electrical issues.

Emergency Lighting Design

Emergency lighting is installed to provide a suitable illuminating alternative when the mains power of a premises fails. There are plenty of components, from design to placement, that ensure emergency lighting can sufficiently handle the very task it was designed for: assisting during an emergency.

RCD Testing, Safety Switches, Testing & Tagging

Residual Current Device testing is the process of safely “tripping” your RCD to ensure it will operate quickly should there be an electrical incident. This is also known as safety switch testing. Your RCD is designed to trip, or switch off all the power to that circuit. An RCD is designed to save lives, and it is vital to ensure they work in the event of an electrical incident!

Great work, friendly and knowledgeable. Anton and his team did the wiring of our new house. He advised us on what fittings will work best for our requirements. They cleaned up after the work was done.

Anton played a critical role in the entire project at Raceworx KTM. The new building required constant “out-of-the-box” thinking. The work they did was 200% above spec; they went the extra mile.

Frequent Questions


Do we charge a call-out fee?

Yes, we charge a call-out fee. The fee is based on how far we need to travel and include the first hours of labour. Feel free to call or email us should you need a quote or more information about the call-out fee.


Should I convert my home’s power system from electricity to solar?

Solar power is a renewable resource that will never run out—and will ultimately save you money in the long run. Once solar panels are installed, they create no noise or air pollution and are low maintenance. While solar panels require a significant initial investment, they are a cost-effective, long-term solution for sustainable energy production. Contact Electotech for a free solar consultation. Learn whether a solar conversion is the right choice for you!


What’s the difference between a three-pronged plug and a two-pronged plug?

The third prong on a plug is a grounding prong. Two-prong receptacles do not have the same level of grounding as a three-prong device. The third grounding prong provides additional protection to the electrical system, the item plugged in, and you from electrical shock.


What does “grounding” mean?

When you use an electrical appliance, the current flows from your service panel to the device. A grounded wire gives the unused electrical current a safe way back to the service panel so there’s no danger in the event of a short circuit.


How do I reset my breaker when it has tripped?

First, you want to disconnect any devices that may have caused the breaker to trip and overload. Breakers are mechanical devices so they must be turned completely off before turning them back on and may require several attempts before it works. If this does not work, then chances are you have a much more serious problem so you need to call Electotech.


What's the difference between an industrial and commercial electrician?

Industrial electricians are basically commercial electricians who primarily work in factories, manufacturing plants, mines, etc. As commercial electricians, they use a three-phase power set-up; however, instead of running MTC or MC cable, they mostly work with RMC conduit that powers motors and instrumentation or control circuitry.


How does a solar geyser work?

The heating up of a geyser accounts for a good chunk of a homes energy use, on average about 40% – 60% of your electricity account is contributed to your geyser.

Solar Water Heating is about as green as hot water can get and is an excellent clean energy source: its fuel, sunlight, is limitless, free and emits nothing when converted into energy.


What is the difference between direct or indirect solar water geyser?

There are two different options when it comes to how a solar water geyser will be connected to your home. This is dependent on whether your area is frost-prone. If it is frost-prone, you’d need an indirect solar water heater. Frost-free areas use a direct solar geyser. So, what’s the difference?

  • Direct – The water moves through the solar collector and then directly into the geyser with the assistance of electrical pumps and controls. If not, it can be done via a natural thermosiphon
  • Indirect – Unlike the direct solar water geyser, the indirect solar water geyser has a solar collector that transfers a heat transfer fluid such as antifreeze. Thereafter, the antifreeze flows through the heat exchanger, which is surrounded by water. The water receives the heat from the antifreeze (but never mixes with it).

What's the difference between a residential and a commercial electrician?

As the name implies, residential electricians work in residential spaces like homes, flats etc. Residential homes mostly use single-phase power supplies – 120 or 240 volts – run Romex cable, and wrap their wiring in sheathed insulation that is generally hidden from view. This helps minimize exposure and damage to the wires, as well as protect homeowners from accidentality touching the wires and being exposed to electrical shock.

Commercial electricians work in offices, shops and stores; usually installing power outlets and lighting. Their wiring typically follows a three-phase approach, with two smaller “legs” running one voltage and a larger “leg” running a higher voltage. Depending upon a business’ power needs that could be 120 volts/208–240 volts or 277/480 volts.

Commercial wiring also tends to remain exposed, although it usually is run inside conduit for protection. In other words, unlike residential wiring that runs in rafters and behind walls, commercial cables may run along the exposed sides of ceilings and walls so it’s easier to access should walls need to be moved or shopfitting is done.
