New fuse box

[Donna74]

Hi all. I had my flat rewired in 2008 & had a new fuse box fitted which is a wylex nh 1104 the wires were also changed from the old type black&red to blue&brown the council are fitting a new kitchen are the contractors are saying they need to rewire which I find hard to believe the fuse box has RCBO in the box can anyone advise ?

Post a picture of your consumer unit (aka fusebox) so we can see what you have got.

How to post a pic is described HERE

Latest regs generally require more than 1 rcd nowadays

Did you see the photo of the fuse box?

Main switch with 5 RCBOs, and space for another 6.
Certainly no need to replace that.

If the wiring is from 2008, then no need to replace that either - however the label on the CU indicates mixed wiring colours so evidently not all of it was replaced.

They are also saying that it's harder to rewire Ie through my plastic skirting they want to surface mount all new wiring but when it was done in 2008 it was done within the skirting

It may be they were old 1 cable radial circuits and they are now upgrading to Ring circuits requiring 2 cables, which obviosly are bigger and may not pull through the existing channels.

OK down stairs lights not RCD protected so I would assume surface cables for down stairs lights.

Rest RCD protected so 2 x 6A for lights 2 x 32A for sockets and 1 x 32A for cooker.

Skirting needs to either have the sockets also in skirting or be the special skirting trunking to comply.

For any non portable appliances over 2kW there should be a dedicated supply so that would include hob, oven, dish washer, washing machine and tumble drier. But it is rare to do this normally hob and oven will share the same supply and the other three are often plugged into the ring final. However one could not say some was wrong insisting on dedicated supplies even if no normally done.

The consumer unit has 6 spare ways so that could be done without fitting a new consumer unit.

To me some one is on a job creation scheme but maybe some thing your not saying. Would be better if you posted your own pictures not relying on some one to do it for you.

this is what they did to a neighbours socket cant understand why they would put a new socket in a leave the old one with a face plat on and at the height looks terrible if they replace a socket...

 

[Donna74]

should it be at that height I thought as the building is not a new build it goes to the existing place IE above skirting

Does your flat really have two floors? If not what do the different up/down socket and lighting circuit breakers control?

The council tend to have a standard for all houses regardless of the owner, the height is to facilitate older tenants regardless of who lives there now.

Rather than JOINTING cables its safer and easier to rewire to the new points.

Removing the old would cause damage to decor and tenants would moan about that, so that was proberly the neatest option.

I'm not sure that even the guidance in Appendix 15 of the regs actually says that. The comment is in relation to avoidance of overloading of ring finals and, in that context, suggests that cookers, ovens and hobs >2kW should not be connected to a ring final but, rather, should be on a 'dedicated radial circuit'.

I would not personally take that to mean that an oven and a hob have to have separate 'dedicated circuits' (rather than being supplied by a single 'dedicated cooking appliances radial circuit'). It would certainly make little sense if a large cooker (involving oven and hob) was deemed fine on a single circuit, whereas if the oven and hob were bought separately, one would then require two separate circuits!
