Tripping fuse

[Mick Leek]

Hi all,

ok here is the dilema. A friend of mine has just moved into a newish house that was built less than 10 years ago. The previous owners had a gas oven and an electric shower.

My friend has installed an electric oven and everytime he switches it on it trips the comsumer unit. He has been told that the shower and cooker have been wired to the same switch. Not sure if it is a spur or ring main????

Can any one help ? should it be on a seperate supply or is it ok as it is and just needs a higher amp res current breaker ?

Thanks in advance
Mick.

Try to think of the fuse as a deliberate weak-point in a circut, so that if you draw too much current then your cable doesn't burn up inside the walls. For that reason, just upping the fuse size without knowing a bit more about your cables isn't a good thing.

But, IMO, given that your cooker and your electric shower are the two most current heavy items in your house, they should both be on separate circuits. I think that the cooker can go into the downstairs ring, if it is less than 13A (or comes with a plug) but the shower definitely wants to be on its own
