Is there such thing as a three phase RCBO??!

Needing to install a three phase circuit for a 8kw three phase heater- connection by a 20a comando

I want to use the metal trunking I will be installing for various 13a sockets- so the circuit doesn't need the rcd protection- but i beleive the 20a comando will..

It will be a new hager TPN dis board

so hows best to get fault and additional protection in TP setup?
 
I did similar a while ago and used a 3 phase MCB at the DB then an enclosure with a 3 phase RCD and 32a socket 'all in one' at the other end but mine was in SWA .
 
I'm going to get some right stick if I ask what a warhouse is. So I'm not going to do it.

Well I'm hoping he means a warehouse and not another similar worded 'house'. :D

You guys need to go to spec savers.
 
Just Googled it...obvious really.

If it helps another divy the same current has to return through another phase if no N.
 
Could you not fit a 20 amp isolator instead and hard wire the heater in , then you would not need the rcd ? Failing that you could get your customer to do a risk assessment and omit the rcd :)
