I just want to add this.
" He will at the very least have to be a master electrician since he's going to be touching your DB..."
I'm old school. Master Electrician is not a normal electrician. Meaning he has done is trade test as electrician.
He needs to be registered with the department. He has to buy a book he needs to fill in to write you a COC.
A normal electrician that works in a factory will not be able to a COC.
He needs to do a wireman licence and pass his exam, then once he has done this, he will become registered.
He gets a number from the department which he needs to include with a COC.
Coming back to master electrician, he also needs to pass exam. Once passed he becomes a master electrician.
My understanding difference between electrician or master electrician.
Master electrician can sign of factories which utilize 3-Phase power. Normal electrician can't do this.
The same can be said for a technician. A technician needs to have some tertiary education. Technical college or Technikon. Currently every call themself as technicians. No qualification what so ever.
This is wrong with our current system.
