Hello,

regarding rdc protection on socket outlets & any circuit under 20 A, do they all have to be protected by this or an RCBO?

Cheers.

 
Residual current device or RCD as they are more commonly known is a generic name for a range of devices, such as, RCCB (residual current operated circuit-breaker without integral overcurrent protection) and the sockets that incorperate an rcd also called SRCD. These devices will detect any earth leakage fault (inbalance between line & neutral) on a circuit that they are connected to.

RCBO's or to give the full title Residual current operated circuit-breakers with integral overcurrent protection, will also detect the same fault as an rcd but they also act as a normal MCB & will trip in the event of any overcurrent above that of which they are rated.

As for your question yes in most cases they do, unless you can fulfill a host of other requirements as laid out in the regs;

"Where an electrical installation is under the supervision of a skilled or an instructed person, or where a suitably labelled socket-outlet provides a connection for a particular item of equipment, Regulation 411.3.3 does not require socket-outlets to have additional protection by means of an RCD".

 
To keep it straight forward, domestic premises, all flush wiring has RCD unless its buried more than 50mm (2") in the wall.

All equipment used outdoors to have RCD, regardless .

Thanks for your help and I had read 411.3.3 - But was still unsure. I know everything we install at work is all rcd protected but I was asked the question myself.

Cheers :)

Thank you for the information, and where is this stated?

Cheers
