New week, but still having the same problem at a house near the sea.
The E/L always trips when Eskom comes back on after loadshedding. Just to test, i replaced the E/L with a new cbi, split a circuit that was carrying too much load, i have checked all the connections in the DB.
I try causing a trip by switching off their double pole mains and flick it back up, but it doesnt trip. I dont want to waste the time there so i gave the owner instructions to narrow down where the problem lies by switching off all circuits on earth leakage when power is off, and checking if the E/L has tripped. if not, then we know that the problem is in one of those circuits. (Ive marked the specific cb's to switch off)
What i wanted to know is are there any other extraneous tests that i have overlooked to help me with this.
