wiring for lv mirror light

[carctol]

Would the power supply for a lv mirror light need to to be run from a fused spur? or just a spur from the lighting circuit?

Lighting circuit.

If this is in a bathroom, are you interested in complying with the law?

This is in a bathroom. So what would be the correct way to connect?

With a self certifying electrician, and notifying building control.

To the lighting circuit. Or a fused spur from a socket circuit. Either is perfectly acceptable and perfectly legal. The lighting circuit is better, more normal, as people expect lights to be on a lighting circuit.

The legality issue I mentioned is that this is notifiable work, and so strictly speaking must either be done by a registered electrician who can self-certify compliance with the Building Regulations, and notify Building Control after the event, or it must be notified to them in advance, and a fee paid to them etc.

Most recent version of my guide to DIY Electrical work and the law.

Nobody can advise you to ignore the law, but if you search this forum you will find plenty of people pointing out that the chances of being caught fitting an illuminated mirror in your bathroom are pretty small.

Is the transformer separate, or built into the mirror?

Thanks for the replies. The transformer is already fixed to the back of the mirror.

OK - so that means running mains cables from the existing lighting circuit to the mirror.

Given the extra risks of electricity in bathrooms, then legal niceties aside, if you're not confident that you can do this safely please call an electrician.
