Power track in offices

[cliffed]

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]

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

Yea rcbo

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.

 

[Toneyz]

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

 

[cliffed]

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

look at my post regarding earth leakage, they might want to change there minds!!

So the 4 way is restricted to 12.6A effectively, I can't see 1.5mm having an overloading issue.

Ok,I personally haven’t seen something like this,this can be directly plugged into the Busbar,obviously the 3m length determinates the overload protection required.
@the moment this lead is actually on the Rcd module side,which is a 40amp rcbo,still not getting it though.
The Chiefs say it’s ok,it’s a factory manufactured plug & play.

Where is that

Call center sockets

So I have had an enquiry about a large open plan call center with around 150 desks. Rented office space, each desk has at least 1 pc with 2 monitors. There is also all the other IT equipment you would expect in a big office. The office sockets are fed from 2 x bus bar trunking runs under the...
