earthing micc cable

[trev]

I'd bet a £ to a pinch of pig poop that this MI is nothing to do with the DNO. Someone on the IET forum has picked up the wrong end of the stick.
In 34 years since coming into the trade I have never seen a DNO feed in MI

Same as, but seen plenty of subs.

Yeah, any amount of MI subs. The building I'm working in just now is all subs in the stuff.

sorry, my mistake. they were referring to lead sheathed cable on the IET forum. you're also correct in saying it comes off a sub/isolator, so attaching something shouldn't be a problem. as for the pyro clips, are they easily available and do they come in different sizes?

 

[onions1066]

All different sizes and yes readily available

Really ?? They are very common round here. Usually in council flats, three phase CO in bottom flat and subs fed from this in pyro with single phase CO and meter in each flat. Also seen them looped from the incoming side of a single phase as well.

Oh well, I stand (sit) corrected

I've never seen this either. I take it the supply into the 3 phase CO isn't going to be MICC. I bet all those subs were actually provided and installed by the project electrical contractor, rather than the DNO.

if there's no earth lead on the gland, the easiest way, IMO, would be to fit a banjo and fly lead.

Or a Piranha lock nut.
