Electricity dead in a single spur

[pmx_super]

Hi,

I have lost power to my undersink electric water heater. It is on the same 30A circuit as my oven and some under-unit lighting, both of which still work.

Where the power cable into the water heater emerges from the wall is another cable, intended at one time for a waste-disposal unit. The power in this line is also dead. The cable to both these appliances is not a large gauge like that which goes to the oven. I believe the element in the water heater is 1.5kW.

If you were faced with this problem where would you begin? I haven't got a clue where to start. There is also a large guage cable that disappears into the wall behind the water heater - possibly on its way to the oven. There is also a standard mains socket that works intermittantly ( ) seated in the chipboard on the back of the neighbouring kitchen unit (this may or may not be on the same circuit - can't tell since it doesn't work properly and it never has).

Could it be that putting all these 'normal' appliances on 'normal' cables on a 30A circuit has fried something? I gather appliances only draw the current that they need though - unless something goes wrong...

Please help. All input gratefully received!

James.

Have a look round for a FCU http://www.brymar.co.uk/acatalog/secma1.jpg and see if it contains a blown fuse, be prepaired to pull the plinths off the bottom of your cupboards and look underneath, etc

Unfortunaly if you don't really know what you are doing, as its hard to guide someone blind to faultfind over the internet, it may be easier to call an electrician

I think you need to call a reputable professional electrician (not a handyman). See if any of your friends and neighbours recommend someone local.
