Bath wall light

[Jupiter01]

Need to first fix for the above and would appreciate your advice.

This will be one of those mains powered, pull cord lights above the mirror. Not an integral part of the mirror/cabinet.

My instinct is to leave a permanent live from lighting circuit at the location of this light but wasn’t sure about the need to isolate it for maintenance, etc.

Also, I have a fan isolation switch nearby. Notwithstanding the earlier point, can I take a permanent live from here?

Thanks in advance.

It’s a light, like any other. To work on this, or any other light, turn off the power to that circuit at the consumer unit. Surely, you know this, after all the work you have done!

Feed for the light will need to be a permanent live, neutral and earth. If you have those at your fan isolator then that may be one of the options for you.

I had some doubts as all other lights will have a switch wire going to them. Is it safe to think of this switch wire as a means of isolation? I.e. with a conventional light, can I flick the switch to off (run safe isolation) and then replace light fitting or should the CU breaker be de-energised in this case too?

Of course, you must isolate at the consumer unit. If you have loop in at the light or at the switch you will still have live conductors in play.
Turning off at the switch is only going to be safe if you are changing a conventional light bulb.

…but “if” everything is wired correctly and you are looping at switch, there should be no power at light when the switch is in off position?

I suppose it doesn’t meet the safe isolation practice as you haven’t locked it off at source. Is that the main consideration here?

Until someone comes along and switches the light from the two-way switch. Ouch.
Can see the flaw in my thinking
