You've changed the supply fuse? The one the DNO owns? Cut the seals?

No, I think he means the one in the fuseboard next to his workshop

Doesn't this require notification / certification etc etc?

SS - are you going to pick up this loaf or not?

Coming to Devon next year, stick it in the freezer and I'll pick it up on the way down. COC.

Yes, it does

Certification maybe, but it sounds like it's not domestic so wouldn't come under part p.
Either way, designing and testing correctly would be an excellent idea.

No it is not the DNO fuse , how on earth would I do that ! , this 3 phase fuse box is in my workshop , feed to it is via a 3 phase 63A / 30mA , taken from "MY" main 3 phase breaker , in a separate building where the DNO ( The Grid ) comes into the property .

I can put whatever fuse I want to ( for whatever power I need ) , nothing to do with the Grid .

 

[spike47]

Yes, it does

No it Doesn't .

Very funny "NOT"

Have changed the Main supply fuse feeding the 63A RCD from 83A to a Lawson 63A ,...

Now you have fitted a 63A fuse, all your original parts will be ok.

and used a 10mm2 cable to supply the 63A RCD , yes I know I really should put in 16mm2 tails ! ,

No, it's all good now.

Hi
Sorry to hijack this , but I have a similar question , well nearly similar , I have a 240V 3 phase supply going into my outbuilding , I need to put a couple of double sockets and 3x 100W ceiling lights ( fixed to a open beam ) , the fused isolator MEM was there when I bought house / land , it has been there for quite awhile , it has 3 x 30A cartridge fuses in it , now without going to deep into this and people shouting you don't know what you are doing , I am not going to do anything , I am wanting to know what can be done before getting a sparky in , ok , I would like to have a Garage unit fitted ( MK 5704SSP1 6 Way Consumer Unit - Weathertight - Super Garage Kit , 1 x 63A RCD + 2x16Amcb , 1x6A mcb ) !!!! .

regards
