Hi

I am upgrading my old wylex rewireable to a dual RCD consumer unit soon and also upgrading the main earth to 16mm and bonding to 10mm, obviously in order to replace the consumer unit i need to isolate the meter tails, ie remove the main fuse, i had a look in the meter cupboard outside and noticed that there are no seals on the cutout and the eyelets that the seals go through are snapped off, i do not see a problem with removing the main fuse as it has obviously been done before, however i will need to access the PME earth terminal in order to connect my new 16mm earth, i have a henley series 7 cut out, i understand there is a few ways of doing this work, i can either do it the proper way and the the DNO out to fit an isolator, connect the new earth into their cut out and maybe replace parts of the cut out in order to reseal it, or i can pull the fuse, remove the screw that holds the cover over the earth terminal, change the consumer unit,connect my new earth and put the fuse back in,which i cannot see a reason why i cannot do this as i am a competent qualified electrician, what are peoples thoughts?? should i get them out once i have changed the consumer unit to repair the cutout and reseal it and deny all knowledge of the fuse being pulled and the earth being upgraded?? there is already a 4mm earth in the earth terminal so its not like im connecting an earth that wasnt already there.
Thanks

I clicked back on this thread because I thought you were going to tell him how to do it.

Call a qualified electrician... or whatever they call them in the UK.

As i said in my original post. I am a qualified electrician.

Stab&Shoot

I have wire all types of buildings, plants, schools, houses, etc. (in US) but the only thing I got outta that was you replaced the ground to your meter and you got something like broken bushings in your fuse box?!!!!!!????? Terminology barrier or are things that different across the ole pond???

mcclary's electrical

Just video tape whatever you do.

Hopefully someone from the UK will respond with some useful info.

Hi: Don't really see your problem to be honest. Although it's not supposed to be done, most of us have had to pull the Service head fuse at 1 time or another to Re-Tail a supply. If your worried about entering the Henley then call your local DNO to repair the cut-out & connect your tails to the supply, whichever way you go with it just make sure you've done all your testing first & everything is safe to Re-energise & leave the CU turned off when you put the Cut-out back in, a Cut out closing into a Short Circuit is'nt a pretty sight.

A Make of Electrical Distribution equipment used in the UK, the Consumer unit (Fuse panel) that he's replacing still has old fashioned re-wireable fuses.

In the UK we've got a Main Fuse called a Service Head Cut-Out, it's fitted where the supply enters the building & belongs to the DNO (Power supply company). The cut out Fuse carrier has Moulded lugs on each end for fitting Tamperproof seals, the lugs that are broken off are the 1's where the seal goes.

We're still called Qualified Electricians.

Yeah, no kidding. Now ask me "what's a dikfer"?

And on another note I think I am gonna start referring to resi panels as"consumer units". It has a nice ring to it.

Thanks for the replies. I have no problem with pulling the fuse and connecting my new earth. Just thought maybe when someone comes to read the meter (which is not very often at all) they will see someone has tampered with their earth connection and have something to say about it. I will of course make sure the installation is tested and the Ze is good. Has anyone had any experience with getting to the earth connection on a henley series 7 cut out? I understand you can drill holes marked on the cover to access the screws but i thought if im pulling the main fuse i might aswell slacken the screw and remove the cover completely. However if i remove that screw does the cover on the permanant live connection also come away and make it little bit more risky.
Thanks
