Fuse box

[hornetstinger]

Any recommendations what fusebox is needed for the outhouse? Will be used for garden equipment. I presume all modern boxes have RCD trip in case of shorts etc (my house fusebox is a modern one)

OK to "double stack" RCD fuseboxes?

If the supply to the outhouse is protected by an RCD or RCBO upstream you don’t need any RCDs or RCBOs in the out house and a standard MCB is fine. Double stacking RCDs is not ideal as you lose selectivity.

However this is notifiable work so unless you are an electrician who is a member of an accredited body, you are not considered competent and therefore you can’t touch it.

Brother is an electrician. Although he doesn't have the qualification as house sparky, but he's worked on high voltage switch boxes.

MCB just fits into existing slots, I don't need to replace that plastic housing?

No, you’ll need to replace it.

That exiting box has re-wire fuses and must be 40+ years old. Nothing modern will fit in it.

The current regs require a metal enclosure and that’s all you’ll be able to buy anyway. The MCBs and the enclosure have to match (e.g. from the same manufacturer).

Not true. You can go down the building control route and do it yourself.

Which costs more than getting an electrician to do it so it might as well not exist.

I think it's the incoming main fuse box requires a qualified sparky? And not and secondary boxes

You don’t need IP rated if it’s inside.

 

[hornetstinger]

There's fair amount of damp in the outhouse though.

That depends on the job tbh.

For a 2 circuit garage fuse box change, it will be more than a qualified spark would charge for the entire job.

I'd have to look up the costs.

But you said it shouldn't exist, not all jobs are small you know?

brother can do it he put in light switch/UK plug/ isolator thing in loft and worked on high voltage stuff.
