TT or PME ?

message from Wheelbarrowbob on 12 May 2004
My brother has an intermitttent faullt on his ring circuit, with the mcb
tripping, its an old board with mcbs and an ELCB. His supply is from a pole in
the garden , TT system i thought with earth leakage protection, but he has had
a spark round ( tripped twice today ) who reckons its a PME system. All i have
seeen at the cu is the incomers and a 10 or 16mm earth cable cable tied to
these ( which may be earth bonding ) but would the supply company use oh cables
for a pme system, and god knows who you phone up now for info.

Yup, PME can be available on o/h systems. A telephone call to the leccy
company should get you (or him) to the records section (eventually -
good luck!) where they should be able to confirm whether PME is
available on the system that supplies him. That doesn't in itself mean
his property is PME, but if the sparks reckons it is, then there's a
pretty good chance that's the case.

Power to the village where I live in County Durham is supplied by
overhead cables and is PME.
The local electricity company is called NPower (Northern Electricity)
but the people who do all the line work is NEDL (Northern Electricity
Distribution Limited).
Best ring your local electricity company and ask if you can have the
name and address of the people who do the line work.
