Wiring for outdoor sockets and lights

irish bloke

Hi

Looking to put 2 sockets and 1 light switch in my back garden.

Plan:

• 16A or 20A circuit breaker at consumer unit

o 17 meters of SWA 2.5mm²

• 13A outdoor 2 gang RCD socket

o 0.25 meters of SWA 2.5mm²

• 5A fused outdoor light switch

o 4 meters of SWA 1.5mm²

• 2 x 100W lights

Have attached a drawing also.
Reckon this is correct but wish to verify?

Thanks.

Your Registered Electrical Contractor is the one responsible for doing the job correctly. Is this what he has suggested?

Anyone care to answer this query for a job outside Ireland

Shouldn't the whole thing be RCD protected? Not just the socket locally?

I don't believe so, but am open to correction.

SWA is mechanically protected via armour all the way to the sockets and overload protected via the mcb. Generally its just sockets and not light circuits that are RCD protected.

I suppose if you did manage to cut all the way through the armoured cable there could be warrant for an CU RCD.

Not sure of the earthing system used at the moment.

@irish bloke:
As this requires working on a distribution board you should employ the services of a qualified electrician regardless of what country you are in. The electrician will advise you in terms of local regulations. It is not possible to determine if the cable sizes are correct as the information provided is incomplete. It would also be inadvisable to use the switch on an outdoor spur outlet to turn lights on and off.

Good luck with it.
