January 17, 20251 yr Good day everyone. I seem to be struggling with an electrical problem. My geyser is connected to the breaker that says 32A, 2nd breaker on the right side of my earth leakage, and my geyser is a 3kW geyser. The circuit breaker has been changed multiple times, I am not allowed to leave it on as I am renting and the owner wants to save electricity. I went to my geyser, tightened all the connections, then I went to my DB board and made sure every bold or screw is tightened. I will switch it on for an hour then turn it off. Is my circuit breaker to small for the geyser's 3kW, or will my breaker be faulty? Before it trips, the wires that go into my 32A breaker will get extremely hot, but not so hot as to burn your fingers. After it gets hot, it trips the breaker and then suddenly the breaker on the right side of the 32A, trips as well. I do not know if this is because of the heat that has gathered in the 32A breaker or what. The wires on top of my 32A breaker gets hot, but the one coming out of my 32A breaker does not get hot.

Not sure who wired up this lot, or how thick the wires are, but if you look at the wire feeding the 20A breaker, this wire should be rated for 63A (the value of your earth leakage) and the same size wire should then be used onward, all the way to the last breaker in line, the CHNT 10A?. The wire in place seems way too weedy to carry that kind of current and that is possibly the only problem that exists... maybe...

Die draad se koper binne is seker so halwe na een millimeter toe. Die lyk net dik a.g.v die insulation rondom. Die breaker se bo kant word warm, daar waar die twee rooi drade ingaan en daarna trip dit.
January 17, 20251 yr Maybe a poor connection on top of the 32A (wire/s not stripped the correct lenght and screw tightens on the pvc ) As said, incorrect supply wire thickness to all breakers. Can be wrong, but mains look like 4mm then 2.5mm to the rest. Live wire (Red) from E/L Neutral to Neutral bar? I think the owner better get a Registered Electrician if he wants to save money.

The wire going into my main, has 5 or 6 little wires inside and does feel a bit thicker than the other ones. The ones going into and out of the other breakers have got one copper wire inside while the ones going into my mais has like 6 little copper wires. Connection on top of 32A breaker has been sorted out, the pvc has been stripped so that it doesn't go inside the breaker point because it can become uneven. The red wire I have no idea it was like that when I came here. I have no idea where it is suppose to go. Edited January 17, 20251 yr by Juan-Jacques Joubert Wiring Update
January 17, 20251 yr No what I pointed out is that the red wire on the Neutral bar is against the code, it must be a black wire. In your Db Red = Live, Black = Neutral.
