3 cables off one terminal?

[industryspark]

hi guys,

came across something today that i dont like but i dont think it actually breaks any regs so opinions please,

industrial 3 phase setup, 300A switch fuse (200A bs88's fitted). the load side terminals & nuetral all have 3 cables coming off them (pvs singles in trunking) feeding 3 seperate db's.....all cables fused protection is there. its sloppy in my opinion because they are using the switch fuse as a kind of busbar but does it actually break any regs cos as far as i can see its a branch circuit which is fine.

probably not good in terms of not been able to isolate individual boards but apart from that......

it is sloppy though i agree.

As long as the cables are individually correctly protected against overload/short circuit (including short circuit for smaller tails between switchfuse and smaller protection) then it is not unsafe.
Just a little querky............

I suppose it is technically a radial circuit wired in a star pattern rather than a daisy chain, so by the regs I don't think there is a breach, but it is a very sloppy way of doing things.

IMO every submains should have its own dedicated supply

my thoughts exactly guys.... why they didnt just fit a chamber for the sake of a few extra hundred squid is beyond me, appreciatte the input though cheers.

for the sake of a few extra hundred squid /quote]

ok, make that a few thousand squid if you include seperate SF's for the db's.
