Outdoor Switch Requirements

[Davey]

Good afternoon, Please can I have some help choosing a suitable outdoor switch?

We had a new consumer unit fitted a few years ago and the electrician provided an outdoor supply from a 20A RCBO.

This goes to a SFCU with neon indicator (fused at 3A ) in the kitchen and then to an IP protected box on the wall outside.

In the IP box a choc block connects the supply to a string of LED lights (total load 50W) and we use the SFCU to turn the lights on and off.

We now want to take a second feed from the IP box to supply a water feature (also rated at 50W). I assume I need to replace the IP box with an external 2 gang switch so the lights and water feature can be switched independently?

* Please can you advise a suitable external 2 gang switch?

* Is this suitable: BG WP42 IP66 20A Switch 2 Gang 2 Way SP from Toolstation (24607)?

* However this is only Single Pole?

* Do I need a Two Pole Switch?

Thank you

Davey

Any that is said to be suitable for outside.

* Is this suitable: BG WP42 IP66 20A Switch 2 Gang 2 Way SP from Toolstation (24607)?

Yes, that is fine

* However this is only Single Pole?

* Do I need a Two Pole Switch?

You don't need double-pole; the FCU will be double-pole so that outside can be isolated.

Thank you very much for your reply.

Please could you also confirm I've got the wiring correct?

I assume:

* LIVE from SFCU to COMM with a jumper to the second COMM?

* LIVE from lights to L1 and LIVE from water feature to second L1?

* All 3 NEUTRALS in choc block?

* All 3 EARTHS in choc block?


Please can you confirm this is correct?

Thank you

Yes, that is correct.
