WELCOME TO  AESA Electrical Contractors (Pty) Ltd...

Established in 2015, AESA Electrical Contractors (Pty) Ltd set out to become a dynamic and valued presence in the South Africa Electrical Industry. AESA Electrical Contractors (Pty) Ltd is located in South Africa, Gauteng. We are a full Service Electrical Contractor specializing in, BUT NOT limit to: Residential, Commercial and Industrial; assisted and Independent living. With over 9 years of trade experience and specialize team, our commitment to quality, safety and professionalism allows us to be a leader within our industry.

The adoption of new technology in the South African market seems no longer to be driven by the desire to have the "latest and greatest". Instead the mantra is if it saves money or leverages and existing investment in new and more efficient ways, then it is worth buying. It is with this focus and mindset that we at AESA Electrical Contractors (Pty) Ltd will attend to our Customers' requirements.We have a passion and determination to ensure Customer satisfaction at all levels.

We believe that the way to promote our business is through the development of good working relationships with our clients. To this end, we aim to provide high quality installations in a efficient, friendly manner, on time and to budget. We endeavor to earn the trust and confidence of those for whom we work. Our objective is to provide, within the cost plan, a service of such high quality that continuing business is encouraged.


In a perfect world things wouldn’t break down. Until then, it is our mission to respond with urgency, expertise and professionalism to minimize the length and frequency of downtime. We’re committed to a high quality of workmanship and provide a safe work environment on all projects. We know that people do business with companies that meet their needs and provide reliable service. We attribute our success to building strategic partnerships and treating customers the way we want to be treated. We believe the quality in our work will represent us for years to come.

AESA Electrical Contractors (Pty) Ltd are here to serve ALL your Electrical CURRENT needs the Fastest-Safest way. Providing the BEST customer service...putting YOU FIRST.


A visual inspection of your facility may reveal electrical problems, but by the time those problems are visible with the naked eye they could have already caused damage and cost you money and downtime. That is why thermal imaging is so critical. It allows us to see things that the naked eye cannot. So before an electrical problem turns critical, we can find it and fix it avoiding costly down time, equipment damage and potential safety issues.

Here are some of the kinds of issues our thermal imaging scan can reveal:

• Faulty Terminal Wires
• Damaged Jumper Wires
• Faulty Disconnects
• Loose or Over Tightened Wire      Connections
• Over Heating Pump Bearings
• Faulty Motor Bearings
• Breaker Problems
• Broken or Undersized Wires
• Faulty Insulation
• Fuses Over Their Current Capacity
• Overheating Fuse Clips

 Again these are just some of the things a thermal image scan may reveal. That is why we recommend regularly scheduled preventative maintenance inspections. Not only will we provide you with our thermal imaging scans but we also provide the following:

• Label all Power Distribution,
• Check wire size and fuses
• Check Motor Loads and Overload Protection
• Create a single line diagram
• Control Panel Inspection
• Breaker Panels
• Lighting panels
• Individual circuits
• HV/LV Breakers
• Arc Fault Breakers
• Power Distribution Inspection



We get the question, “What’s the difference between amps, volts and watts?” enough that we thought we would address it here. There are some fairly complicated answers to this question but we thought we’d try to simplify the answer by using an analogy.

If we think of electricity as water flowing through a pipe it can help us understand amps, volts and watts. Amps would be the volume of water flowing through the pipe. The water pressure would be the voltage. Watts would be the power (volts x amps) the water could provide (think back to the old days when water was used to power mills). So with this analogy in mind the definitions below for amp, volt and watt should be easier to understand:

Amp – an ampere is the unit for measuring electricity. The accepted standard unit used for measuring how fast an electric current flows is an example of an ampere.

Volt – the basic unit of electromotive force in the SI and MKS systems, equal to the electromotive force, or difference in potential, that causes a current of one ampere to flow through a conductor having a resistance of one ohm.

Watt – the basic unit of electric, mechanical, or thermal power in the SI and MKS systems, equal to one joule per second or 10 ergs per second (of a horsepower): for electric power it is equal to one volt-ampere.

Back to our analogy; electricity is the flow (like water) of electrons through a conductor like a wire. The rate at which electricity flows is measured as an electric current. The electric current is measured in amps. What makes the current flow? In our water analogy we could say a battery would be the pump that makes the water flow which creates pressure in the pipe. The pressure is the voltage. And as we said before the watts are the power the water could provide (like to a mill wheel). The watt is a measure of how much power is released each second.

We hope you now have a better understanding of the difference between amps, volts and watts.
