Changeing CCU and removing main head fuse

[justjust1]

Hi all,

I am just finishing my Level 3 City and Guilds level 3.

I am going to replace an old re-wire-able fuse type CCU with a dual RCD CCU. When replacing a CCU in the past i have just removed the main head fuse to disconnect the supply going to the CCU.

But someone at my collage has mentioned that you are supposed to contact the supplier and they will send someone out to do it? This seems a bit pointless as they will then have to re-connect after i have finished?

Can someone clarify?

Also if i can just remove the main head fuse, where would i get the wire which goes in to stop people removing the fuse? And what is it called?

Thanks

Can you imagine everytime a rewire was being done having to call the DNO out to pull a main fuse. We're qualified sparks ffs, probably more experienced than any jim, bob or Harry the DNO send and thatt would be another £150-£200 to get Jim , Bob or Harry out!

My point entirely! Just want to cover my own back!!! Any idea what the cable they use to seal the main fuse is called, might buy some of them and seal it myself!!!

Thanks for the doc, worked in Internet explorer i was using Firefox! seems interesting, but surely they have no way of checking if it is re-sealed after removal and re-connection?

So not something i should be overly worried about doing then!

Pheww did not fancy paying a cowboy from one of the electricity boards to pull a fuse out and stick it back in again!

Thanks all!
