Thanks allot for your confirmations in the requirements that i need. One more thing, the electrician that has just visited said the extra RCD MUST be in the kitchen beside the current mcu not in the loft, is this correct?

I would never touch a job anything like this myself, blowing the house up is not something i require!

I already had an appointment for the electrician to come this afternoon, that is why i wanted to confirm and know everything i required from him to do the job and not be 'fobbed' off. As some electricians have said there is no way i can run a shower on the current circuit or enclose the wire in piping and 10mm must be used in any shape or form.

Regards

length of cable run?????anyone

 

[justinbowness15]

These are approximate lengths:

The MCU is in the kitchen on the 1st floor, if the wire goes directly vertical into the loft (normal 2 story detached house), maybe a few turns here and there, 10-11 metres? then across the loft to the bathroom about 8 metres.

the reason the RCD should be at the source is so it protects the cable. this is required if the cable is buried in a wall < 50mm depth. volt drop should not be a problem with 8.5kW on 20m of 6mm cable.

It's really hard for us to be dishing advice out to someone who says they are employing a professional electrician. You really need to find someone you are comfortable, then trust what they tell you.

yeah, i understand what you are saying. I just wanted to get a good idea from experienced electricians on what should be / could be done. I know other things cannot be seen from what is not known but thanks for all your help and advice, its much appreciated.:yes:

With locations containing baths or showers, the requirement is to protect the circuit(s).
So yes the RCD should be in or as close as possible to the Consumer Unit (or Fuse Box), not in the loft.

i though that over 13metres the cable needs to be 10mm for an 8.5kw load?7.5 maybye--
justin says its about a 19-20 metre run
if the shower is used for a longtime,the 6mm cable will warm up, especially in a loft in the summer?
