Meter leads

[KEVINDOE]

Hi all,

A question concerning fusing of meter leads when over 3 meters long, the nice man from the niceic says there must be 2 pole isolation , and fusing, I have come across many different attempts at this , including r.c.ds,, main 60947-3 incomers, single pole m.c.b, Does anyone have a method that complies ?

ive used switch fuse before, and NICEIC registered man who tested it after was happy. I think it depends on your DNO also. We got EDF down here

Yeh, switsh fuse i have used before now, is there a double pole m.c.b availible ? spose you could use a 3 phase breaker in an enclosure?

there are DP MCB's available, ive just typed it in google. That should provide islolation and overcurrent protection.

Ahh , good, i think that is what the area engineer was angling at, also as it has to be as close to origin as poss, small enough to fit into the wall cabinet if your lucky !

Dont forget to check with DNO they decide the length of the tails and some of them insist on 2 metres as maximum length of tails.

I guess the BS number would still be 60898 ?
