CU change in cupboard under the stairs

[Miketwinny]

Hi
I want to change the old fuseboard in the cupboard under the stairs to a new CU.Would I need to reposition it to comply with part M build regs for easy access or would a straight swap be ok.

Just swap it where it is. If it were a new build then Part M would come into play. Consider providing an emergency light in the cupboard, easy enough to do and provides piece of mind.

Stairs must be removed.

Stairs must be removed.

And lift shaft built

I'm just wondering why you would even need to ask this question??

Has that installation previously been on fire?!

Looks like somethings definitely gone Bang in the past, don't know about a fire though!! lol!!

Is it just me or should the grey L & N cables connected to the j/boxs after the isolator be the same size as the cables coming out of the isolator then only reduce down in size when they are fused to the relevent sizes? or is my eye sight going...

As long as the cut-out fuse covers the smaller of the cables then I think everythings ok...

one would assume that OP would rectify that on a CU replacement.

Or the use of a 6kW motor to a bedroom heist !:mickey:

 

[shocking_eg]

most economy 7 supply cutouts often have 4mm double insulated tails coming straight from the henley blocks , no other protection for these conductors other than the 100A main fuse

DNO dont have to comply with out regs ! lol

although in this pic it does not seem those tails are associated with the supply company as they are after the main switch

this depends whether you are domestic industrial or commercially trained
domestic changes the board
commercial moves the board
industrial moves the stairs

the grey L & N cables connected to the j/boxs after the isolator go to an electric shower CU which will be made redundent.
