Hi guys. I need your help as I'm more confused than ever having spoken with another Electrician. He told me I cannot move the incoming supply over 3m unless it was armoured 25mm2 cable. Having the fused isolator switch and then running in 25mm2 non armoured cables apparently isn't allowed?? I've had a look at the 25mm2 armoured cable and it is not going to be a easy cable to manipulate. Help!
 
Can you not employ either of these electricians to just install and certify?

And to the other electrician that advised you that proberly is his generic design he does of the top of his head for a simple domestic installation.
 
You would need to look at RCD protection if not using the armoured cable. That housed in an enclosure, along with the 100A switched fuse unit, and you're probably at a similar sized setup to having just placed your consumer unit there.
 
The problem is the builder who has undertaken all the wiring work is expecting to turn up tomorrow and install the cable (which I should have purchased by now). He is not a qualified electrician and instead gets his work certified at the end. I thought I had the solution for him i.e. the isolator switch and the double insulated cables and these were the things I went to purchase. Unfortunately the electrician in the shop explained to me that I could not do this. He quoted some regs. 434.1.2 ??? Can you really not move the incoming supply using a fused IsolatIs switch and running in double insulated cables??
 
The double insulated tails would need installing in such a way that doesn't require RCD protection.

What happens if he gets things badly wrong and injures/kills himself or someone else, or a fire results in the meantime? Whose insurance policy covers the liability? Is your home insurance still valid if you employ a non-electrician to carry out a CU replacement/move, which is notifiable to building control? What/when is "the end" in this context?
 
Thanks for all your help. I will have to or everything on hold until I can get an electrician to do the move. All the new wiring has already been moved to the new CU spot. If it hadn't I would have sicks to the original location of the CU. More hassle than its worth!
