1436 Questions: Electrical


The previous owner of my house tried to install an electric shower. It has a copper pipe running through the ceiling and seems to be connected someway to the immersion heater.

It blew all of the fuses the one and only time I switched it on and it's quite obvious that the wiring is dangerous. I want it removed. A plumber who visited for another reason says he has never seen anything like it and it's amazing the house hasn't caught fire! I want to know who to contact (would it be an electrician?) and roughly how much it would cost.

Maximum load cooker requirements


I have recently started to renovate the kitchen and have a new range cooker. The cable that supplied the old cooker is a 2.5mm^2 which I assume to be 30A. I know that cookers should have a 6mm^2 cable. However after speaking to hotpoint they said maximum load would be 22.3A, from this it seems that the current cable would be capable of the full load.

Can someone give advice on if the current cable is OK? As replacing the cable would be a pain in the **** as the walls have just been replastered.

The cooker is a hotpoint EG902GX



Thanks for all of the responses. I am going to get the cable replaced with some 6mm or 10mm. My logic is 6mm will be ok for now but should the wife want to have an all electric range in the future then 10mm would seem sensible.

Also the circuit is protected by MCB and RCD from a Dual RCD CU. There are also two other on the RCD, the kitchen ring and downstairs lights.

A quick question about the Diversity Factor. I can understand how this would work if the cooker was full electric ie 2 ovens, warming drawer, 4 rings + socket. Then I can see how you would not assume full load.

How does this work when there is only a double oven, as I would assume that there will be times, such as when you turn both on to heat up they will be drawing maximum current? Is this correct or am I missing a trick.

How deep should wires be chased in to walls?

Is there a minimum depth for wires to be chased in to walls? We've just had a full re-wire and were about to start decorating but in places the cable is coming through the plaster, to the extent I can read the writing on it. Other bits I've noticed are staring to crack and come away where the plaster over the wire is spread so thinly, presumably because it's not deep enough. Is this acceptable? Should he have used some sort of capping for the cable? And how would it be best rectified? He's coming on Thursday to look at it so any information to hit him with would be appreciated.

When we moved to our flat, the washing machine was in the bathroom. We bought a new one and Curry's wouldn't install in the bathroom (understand why) so it was set up in the kitchen (fittings existed)

now we want to install a dishwasher in the kitchen and move the washing machine back to the bathroom. Before I post a job, I'd like to know whether an electrician will actually do this job, due to the 'electrics in a bathroom' issue. We're find with it - there is already a power supply and the pipes for the washing machine, just want to know whether someone will actually do this. Otherwise we need to re-think the new kitchen design! Thanks :)

Update 09/03/12 - thanks for the advice guys, will not be moving it back to the bathroom following your advice!

What is a reasonable price to fit exterior lights ( 2 flood lights)?

If only the flood lights were to be supplied by me.

One for the fornt of the house (3.5m away from mains under the staircase)

One for the back of the house behind the kitchen (5m away from the mains under the stair case)

Also what would be generally involved?

Would I have unsightly wires indoors?

Would this type of work require certificates?

Earthing a property

My electrician has earthed our property by means of sticking a long metal rod in one of the flower beds in the garden. Is this the right and safest thing to do?

Thanks to all those who have responded thus far...appreciate your reassurance and yes the electrician has advised that he is certified.....

Thanks electrical Safety Services!! this is exactly what he has done... I was thinking about it being accidently damaged which is why I posed the question.. The job is not finished yet and he has to come back at second fix so I do not have a certificate yet. I will point this out to him and see what happens. Thx again for your sound advice..
