MCB tripping


Postby cilcain24 » Tue Sep 29, 2009 11:41 pm

I live in a two storey house. It is about 20 years old. About 3 months ago, the upstairs lights and the central heating fuses in the Hager Consumer Unit (with fuse carriers) kept on blowing up every few weeks. I changed the Consumer Unit to new one with MCB, but the problem did not go away. Both MCBs trip up as soon as I turn them on. Also, the Immersion heater in the Consumer Unit goes to the same one as the sockets, is that correct? When I use a separate MCB for it, that one also trips after a while, but seems to be working fine when sharing the socket's MCB. Is it safe to leave it like that? Your help and advice is appreciated.

Best option get an electrician to look at it, sounds like something is shorting.

Are the fuses the correct ampage? Your heaters should not be connected to the same MCB as your sockets. You need to get a leccy out as soon as possible to have a proper look and test the individual fuses.
