- This is how we do things properly in South Africa
When you contract an Electrician ask him for a copy of his Wireman's Licence, and a copy of his DOL Registration Certificate, don’t let him just show some paperwork that in any event will mean nothing to you. When you have these copies phone your national office of the DOL and CHECK that you are dealing with a Registered Electrician. Most important is to check the electrician’s credentials before any work is undertaken on your property.
How does someone become a Registered Electrician
When the Electrician has passed his (NTC 3), he would then be allowed to do his trade test.
If successful the Electrician would then be known as “Qualified”, but he would not be a Licensed Electrician. To become Licensed Electrician, a Qualified Electrician would have had to write and pass an exam on “Electrical Installation Regulations”.
When all this is done and the Electrician has served the appropriate time and passed all the examinations and Trade test the Qualified Electrician will be issued with a Licence from the Department of Labour.
If the now Qualified and Licensed Electrician wants to work as an Electrical Contractor he must further register with the DOL as a Registered Person. Please note that this registration must be redone every year.
As a Registered Person this Electrician can now issue ElectricalCertificates of Compliance (CoC). No other person other than a Registered Person is allowed to issue Certificates of Compliance.
There are three categories of a Registered Person.
A. Electrical Tester, who can work on a Single Phase installation Basically a normal house supplied with 220 Volt electrical supply
B. Installation Electrician who can work on a Three Phase installation. Normally buildings and factories supplied with 380 Volt three phase supply
C. Master Electrician for Hazardous Locations, basically petrol stations, mines, flammable areas.
An Electrical Tester cannot issue a (CoC) for a Three Phase installation. An Installation Electrician can issue a (CoC) for a single phase installation but not a Hazardous Location, and a Master Electrician can issue a (CoC) for any of the above installations.
You now know what a Registered Person is. He is not simply someone that has a good idea of what to do, and he is certainly not a “Handyman” that professes to be a “Jack of all Trades”
What are “Electrical Installation Regulations?”
As stated before, part of the qualification process is that an Electrician must pass the exam on “Electrical Installation Regulations” these regulations are actually the “Bible” relative to how an electrical installation shall be installed.
These regulations are the “Code of Practice” for ElectricalInstallations namely, The South African National Standard SANS 10142 - for The Wiring of Premises.
SANS 10142 is concerned with the basic safety of ElectricalInstallations. To ensure the protection of people, animals and property and the proper functioning of a fixed electricalinstallation, the aim is to ensure that protection from hazards that can arise from the operation of an electrical installation under both normal and fault conditions.
An electrical installation has to provide protection against
- Shock Current
- Over Current
- Fault Current
- Over voltage
- Under Voltage
- Excessive Temperatures
- Electric Arcs
If any of the above arises, the protection should automatically disconnect the supply or limit currents and voltages to safe values. In the case of under voltage, the protection should ensure that dangerous situations due to the loss and restoration of supply (for example to a motor) or due to a drop in voltage cannot occur.
The code only covers the electrical installation and the circuits feeding fixed appliances, but does not cover any appliances, for example stoves, geysers, air conditioning and refrigeration plant.
What makes the Electrical Installation Regulations Law
The Occupational Health and safety Act, 1993 (Act No. 85 of 1993) (OHS Act), which is administered by the Chief Inspector of Occupational Health and safety of the Department of Labour, requires that electrical installations comply with the requirements of SANS 10142. It also requires that a registered person, as defined (Master installation electrician, installation electrician or electrical tester for single phase), will issue a Certificate of Compliance together with a test report.
The certificate shall be in the form of the Certificate of Compliance published in the Electrical Installation regulations, and the test report shall be in the form of the test report published in the Electrical Installation regulations.`
