Here is an interesting one.

How would you interpret a plug sockets on a machine ... like a CNC lathe for example ? It doesnt form part of an electrical installtion but it would be covered by the occupation safety act.

I have a few factory full of machines with single phase an 3 phase socket outlet ... the industrial gewiss type ... not one of the machines have an earth leakage unit ... the sockets are used for parts of the machines and item like chillers or dryers which are positioned next to the machine.

The question do you tell the customer that they have to outlay tens of thousands of rands fitting earth leakage units to each machine or you just leave them because they are old machines and have been like that forever.

When you fit a new plug ... do you try fit an earht leakage in an already full control panel?

I need to find an RCD/ circuit breaker to use for these sockets at an affordable price.
