Toggle switch lights in Zone 1

[benstoneham]

For asthetic reasons (are't those always the worst!), switching regular IP65 GU10s mounted in Zone 1

Thought is to have SELV 12V DC (supply outside zones) switching relays (also outside of zones) for the lighting circuit ..

Other than the obvious potential flaws (switches not suitable fgor environment etc etc), can anyone see any other issue with this approach (practically or from BS7671 perspective).

Sorry, I dont understand your question?

Are you saying you want to put a light switch in a bathroom to operate GU10 lights?

In what zone would the switch be? What sort of switch do you want to use?

 

[benstoneham]

Yes, conventional toggle switches (not specifically designed for the environment), GU10s in Zone 1, Toggles Zone 2.. 12V SELV for switching relays (and the relays themselves) outside of Zone 2 (would have been outside of Zone 3 under 16th too).

I realise that we will run into 'appropriate for environmental conditions' here.. although I think this will be mitigated by choosing toggles made from suitable materials (actually thet are to be old 1930s style bakerlite / ceramic base.. mechanically they should be OK I think).

I know it sounds nasty... but other than the environment point, is there anything else that is an obvious problem?

The environment thing is a big issue!! The switches must be suitable for their environment.
Should be OK is not good enough, they must be the correct IP rating for and suitable for use in the zone.

 

[benstoneham]

Yes fair enough, I take your point.... I'll see if they can be located outside of zone 2.

From a safety point of view you'll be fine with 12v SELV on the switches to operate your relays. Whether or not the switches themselves will stand up to the potential water ingress is another matter.

ZOne 2 finished 60cm from the bath/shower. Go 17th, there's no zone 3 (switches must be suitable for use in the environment though).

IMHO there's no problem with regular light switches in a bathroom outside zone 2 (17th ed install).

I reckon they get a lot less damp and steam than (say) a 13A socket in a kitchen next to a kettle!
