PIR Codes

Hi, im doing a PIR . I was just woundering what the code would be for meter tails longer than 3m without a kmf isolator switch? thanks

If it was marginally longer I would code it 4.....if it was way out 2......I cant see any guidance on this so it's your call,but thats what I would do.

Tricky one this as it's the DNO that stipulates maximum length of tails before additional overcurrent protection is required.

BS 7671 does comment on it, although vaguely and basically says that the distributor should be consulted.

I would code it 2 also, as IMO a little bit over is still over and if a situation did arise (although unlikely) all fingers would point at you regardless of how much over the max it is.

As with all PIR code questions, all IMO.
