Hello,
Need some assistance please,
Had a new geyser installed at my dads place - very old house and electrical installation.
The geyser that was replaced was not used for a few years and the piping (old iron type) started to leak in the ceiling so we decided to put a new one in.
So...
New geyser installed and old geyser wiring extended to new geyser as its in a different location with new piping.
The new geyser has power on it with the earth leakage off / down...
So we put the geyser CB off and put the earth leakage on... Everything works fine...
The moment we switch the geyser on it trips the earth leakage...
Additional Info
3 phase power
Very old DB and possibly wiring standards with the double thickness CBs compared to new ones
Old geyser is still in ceiling just fully disconnected and drained now
The house does have an additional completely new geyser installation from a few years back that is working perfectly fine.
Any suggestions welcome, thanks in advance...
Installers only suggestion is that the earth leakage is bypassed and the geyser does not have a proper earth (they connected to the existing earth from the old geyser)
They also tried disconnecting the earth in the geyser terminal block on the side with same result.
