On the back of a thread I started I thought I'd start this since there doesn't seem to be one and I'm sure we all have a right good few that would scare those in the know.
How many supplies does one need!
Cable Raggle Extra
Not so much Shame but old
Any idea of age?
Agree with madmac we do the same, metal capping over cables gets earth even with the circuit on a RCD. Must be a Scottish thing.
However I changed my mind about the whole thing a few weeks ago, now using pvc. At the end of the day its only for trowel protection.
The property consists of a block of flats with the shop below, in every flat there was something.
These were from the flats:-
Incoming Supply (up here they are called laterials, the supplies to the flats through the common close, not sure if this is the name given elsewhere)
No need to guess...
We recently start the strip out of a newsagent in the Glasgow area and the following photo is what one of the guys found when he open the dist board.
Spot the issue?
It annoys me that we get pulled up for silly things when we're having an inspection from the NICEIC / SELECT and yet...
I remember years ago all underfloor busbar trunking / tap-offs to floor boxes were always fed from MCB's. The main issue related to earth leakage from the old CRT monitors.
