pulling main fuse

[dean7828]

hi just wondering if you can become qualified to pulling a main fuse so to isolate a distribution board, i know its supposed to be done by the suppliers, is there anyway around this?

thanks in advance

I couldn't have put it better, what's in it for the suppliers? Nothing.

This has been an interesting read for me as when my CU is upgraded, I've also decided to have a 100A rated rotary isolator to be installed before the CU (but after the main fuse). Meaning I can lock off at isolator and not touce the DNO's fuse.

However, my course tutor always said that cutting the seal on the main fuse and pulling the main fuse is OK. It was if you cut the meter seal, this is a big no no as it may then look like you've tampered with the meter readings to turn it back.

That's course tutors for you, opinion mixes with fact plus a bit of rumour stirred in and then it's passed around.

I have never seen a sealed cut out fuse, honest.

However I have a pair of Knipex Nylon Fuse pulling pliers for old Lucy's - they are prone to disintegration

wow i must have been lucky to have always worked on installations where someone must have already of removed the seals!!

Hi guys, I want to change the consumer unit in my business. I can't turn off the supply to change the existing CU without pulling the supplier's fuses. I phoned supplier who quoted £80 to put in an isolating switch. Does this seem like a fair price? I was wondering if I should leave this job for a while as I've seen that suppliers are now changing all domestic meters to digital ones due to a change in Scottish law. Anyone know if this will apply to commercial premises as well? I'd think that they might put in an isolating switch for free if they had to change the meter.
