Is this acceptable ?

[QSGAZ]

Whats your views on this? Would you be happy doing this?

 

[RISElectrical]

ooooooo you could get a nasty cut from the sharp edges where its been cut.... other than that whats wrong with it?

Only joking and no I wouldn't be happy with it, happens quite a lot tho

 

[QSGAZ]

is the anything in the regulations or anything that would back this up as a "not to do"? a sub carried this out on one of my sites and i just dont if it is acceptable or not?

On an I&T I'd give it a C2.
There'll be something under safe isolation for that.

 

[ColinR132]

Oh dear, oh dear...!

 

[RISElectrical]

There is something in the regs (not got a copy to hand now) stating something about devices have to be used for the purpose designed for or something along those lines. As above I would C2 i think. If it was the other way round and there were single pole devices used for a 3 phase item that would be a C1 in my book.

 

[RISElectrical]

Also I would be concerned as to what it is feeding? I am only assuming that he has used a TP device for a SP circuit, and that the other 2 ways are clear.

Oh aye, if you're on site, insist it needs changing immediately, virtually free beer money for tonight.

As Archie said, isolation is it’s downfall. Get it changed if you can.

Reg 537.2.2.3 A device for isolation shall be designed..........

The device is not intended to 1 + 2 pole iso.

537.2.2.4 Provision shall be made for securing off-load isolating devices........

Can it be locked off in that condition?

537.2.2.5.......... isolation shall be preferably be provided by a multipole switching device which disconnects all applicable poles.......

Which in this case it doesn't.


Take it out and get a new one in before some numpty turns on a phase whilst someone is working on it.
