Has anyone seen a service head like this before?

Do let us know what UKPN say when they come out.

Usually check all that before starting an installation, the service head, bonding & tails condition & any N to E surprises.

Looks like you have pulled a 60 amp rewireable naughty naughty, give the DNO a call they are into replacing such a cut out.

Last one of those I had to deal with, was buzzing, had steel legs instead of copper.
Had to re-tighten all terminations, file corrosion from the legs and adjust the legs so they made better contact.

Hello spark dog, Yes in future I will be doing the above because I don't want this again.
If the head looks old I will say get ukpnw out to check it as it's suspect.
When you say N-E surprises do you mean you check for current flowing down the main earthing conductor or IR check?

I know mate I won't be doing it again I was lucky this time by what some people have been saying.

Yes i will do they are coming out this morning, I hope they don't pull her power supply?

the problem with pulling those old service fuses is that the ceramic could break in you hand and give you a lethal shock. even the DNOs are wary.

With respect I would expect an electrian to understand that N-E surprise = N-E fault without any further explination. In other words tie LN and test with respect to E.

Well LN-E I would have understood I was just not sure why you specifically just spoke of a neutral to Earth fault.

Good shout I am emailing clinet not to make this priority, side point is that we have a 2.5mm copper cable supplying the entire house which must have been like this for some time bloody hell!!!

2.5mm bare copper wire is roughly round about, in the same ballpark, approximately, equivalent to a 100A fuse wire, so what's the problem? [/QUOTE]

remember years ago being disturbed while I was doing some testing to find circuits in a very rubbish install & I used bit of 1mm as a link & forgot & put the main fuse back in with link still in place the 1mm copper held up the main 60amp fuse did not.
had replacement head fuse on board. new what I had done immediately removed link re-instated power & finished testing.
that 2.5mm will probably hold as long as it has been in place.

Have a think of an RCD and which faults it can detect compared to an MCB and get back to us...

 

[UKMeterman]

There is also the small mater of the current capacity of the meter and other suppliers works that you are tampering with....

 

[sparkdog]

An IR check.

After a staff discussion I am closing the thread on the grounds that what is being shown is illegal and also because we have a lot of trainee electricians on the forum and I don't want them to think that this is an acceptable way to do things.
