Melted main switch cable

Got a callout on Thursday smoke head activating alarm in distribution room. Smell of melting PVC bit of investiagtion found this. Not the way I would have connected it am going tomorrow for a shut down new switch and cable with crimped lugs and proper connections.

Not sure how you would connect to that switch using crimped lugs?

What size supply was it?

Is it just me or does L2 look a bit smaller than the others?

You may find you need to replace the terminal too, if it has suffered any heat damage which it probably has.

It's the posxy new colours.

They just don't perform the same :-/

Looks more like Black tri-rated panel wire .

It's clearly got Bn/Bk/Gy tape on

With NEW COLOUR tape

Just a jesty joke!

Lec, was not having a dig.

Just saying to the op it may be Tri rated.
Possibly straight off the main bus bars.
Should not really replace with normal cable and crimp lugs

IT is Tri rated now replaced with new piece and lugged terminals the proper way. This was shoddy work just stuffing it in and tightening the screws.

I think I prefered it the original way.

There is one hell of a lot of exposed live parts on show there, and certainly no barriers between the phases.


I pity anyone who has to work in that board now.

What were you thinking of?

"just stuffing it in and tightening the screws" ?? = looks for all the world like that's how the cables are supposed to be connected, and then everything safely tucked away under that cover - you know, the one that once upon a time needed to be removed to gain access to live parts...


You should get back in there asap and do the job properly.

Furrels on the end of the tri rated would have been better.

I agree, tri-rated into terminals is not great.......but bootlace furrels are the answer.

You all do panic.!!

How could I take the picture with the barriers in place??

Sometimes I do worry.

There are barriere in place.

RF Lighting WHY would anyone be working LIVE in the board. Live working is not allowed unless I missed something recently??

 

[RF Lighting]

Testing and inspection.

How do you do a Zdb if the board is not live?

Show me a picture of the MCCB or isolator with the guard in place.

I have worked in loads of squareD panel boards, and never seen anything like that.
