Bathroom lights

[nedthehorse]

I want to fit 12V downlights in my bathroom, on the same circuit I want to add plinth lights in the bath panel. The plinth lights come with a mains plug though . I also want them both to be controlled by a ceiling mounted occupancy switch
Please help

Are the plinth lights rated for the zone?

   Be aware that that is notifiable.

   Do you mean a plug, or a wall-wart power supply?

   That will drive you mad.

The plinth lights are rated IP67. They have a plug (not a wall wart).

Well you could in theory connect them in outside the zones, which if you have a bath panel that a tool will be needed to access the underneath of it, will then be outside zone.
Some logical thought should be processed though, when making this connection. As the plug can not be used, I would use suitable IP rated outlet to hard wire with, and RCD protection on circuit.

I was thinking of putting the transformer for the plinth lights in the loft and running the cable down to under the bath?

If you do that and the connection under the bath is sensibly IP rated for under the bath bearing in mind, sometimes the pipes/waste and seals leak.

That might be a problem since most transformers have a max limit on the length of the cable between the transformer and the light - sometimes max is 500mm sometimes even less. The transformer manufacturer's instructions should advise on the max length.

is it still possible to hard wire the plinth lights into the lighting circuit so both them and the downlights are operated by the occupancy switch?

Yes but you would have to bring the switch live, neutral and earth to say an IP rated junction box under the bath and then connect the transformers to that and the lights.

As above you will need to connect the sensor to both.
