3m max meter tails - DNO rule or BS7671?

[ban-all-sheds]

Yep - something else for which we have to thank the LFB !

It's not their fault.

but no additional fuse likely to be installed (for tails >3m) would be likely to discriminate against theirs, anyway (particularly if, as would probably often be the case, it was of the same rating as their fuse!

Or higher.

I really do hope that when (not if) someone is harmed or killed because of a metal domestic CU, that happening gets widespread publicity.

Or higher.

Yes, or that.

Does anyone fancy ordering a new supply, having the argument, and then somehow

After reading what was originally stated as be the reason (apart from the ludicrous 'or isolator') I think it highly probable that a misreading lead to the rule in the first place and no one can question the instructions of the DNOs.

The switchr isn't so bad requirement on its own when you remember they need to remove all the load from the fuse before pulling it.
Somehow that need for a switch was merged in with an unrelated requirement that maybe happened to be seen in similar situation

That would make sense, but if the view that the late-lamented westie repeatedly expressed in any way represented the view of his employer (a DNO), they seem to be pretty 'anti' the idea of isolators, on the grounbds that they represent an additional 'point of failure' that results in an appreciable number of DNO callouts.
