I had to replace a faulty earth leakage this morning and realised that neither the stove nor the geyser is on the earth leakage. I fixed it by feeding the geyser's circuit breaker from the EL, but it trips the EL as soon as the CB is turned on.
It is an old house (from 1962) and the DB was brought up to spec when I purchased it 6 years ago. At that time the house still had its low pressure geyser. This old geyser has been disconnected six months ago and the electrical cabling has been extended by 5m to where a new geyser was installed. The new geyser is also controlled by a geyserwise unit.
1. I've seen it discussed that it is ok for stoves to not be connected to EL. Is that the same for geysers, or do they have to be protected by EL?
2. could the geyserwise be the cause of the EL trip?
As soon as it cools down up there I want to start troubleshooting the problem. Apart from bypassing the geyserwise, what else should I check?
Any help would be much appreciated.
