Power track in offices

cliffed · Jun 20, 2019

Giving a hand to some sparks on a real nice job..but..
Anyone fitted the power track system,bus bar & the plug off’s to sockets.
It states they are 3 metre lengths,if over then these leads need to be fused.
It’s a 63 amp system,with a 40 amp Rcd,also plug in 1.5mm flex,can’t get my head around this.
It’s all factory made,& all the bits have been sent,but why a 40 amp Rcd protecting the cable.
So it’s 63 amps,leads are 4.0mm straight from plug off,then 1.5mm of the Rcd.

4mm2 supplying power track is a bit small.
I’d expect 6 or 10mm2.
Is the RCD protection in the board at the plugs or at the sockets?

I think the power track we installed had a 32A protective device feeding the track and the floor boxes had 4mm from the box to the plugin installed inmetallic flexible conduit.

Thanks all,yes the Rcd is for the sockets,I think the Rcd will need to be changed from 40 to maybe 32 or 16 amp.
Especially with the 1.5mm supplying sockets.

Why???? or do you mean RCBO?

As above, what's the reason for down rating the current of the RCD?

cliffed · Jun 20, 2019

There are other sockets plugged into the Busbar,with 2.5 flex on load side of rcbo,that’s rated @ 40 amp.

If its prefabricated by the manufacturer then take it up with them, don't just alter it without their consent.

Exactly,the sparks are retrofitting the leads theirselves,I told them it’s compromising the install ,thanks

Yes, but someone will test it.

Is it one double socket or two singles on this 2.5 as I could understand that?

This is the sort of equipment,this plugs straight into the 63 amp bus bar system.
