HI All,
Looking into power supply to client's 400V 20A 3P+E welding plug. I would appreciate some thoughts on the following:
It seems clear that according to SANS10142 we do require "earth leakage protection if the circuit is intended to supply portable or stationary class I appliances". What is not clear is the size of the earth leakage. The 30mA requirement seems to cover only the normal 230V 16A sockets ... but what about the Welding Plugs? I know in the past 30mA can cause nuisance trips for Welding Machines etc..
What do you guys use for Welding Plugs earth leakage units ?
Thanks In Advance ...
