Bathroom Isolator Switches

[AdamCH]

Can anyone tell me if it is necessary / good practice to fit islolator switches to bathroom electrics?

There are 2 circuits from the consumer unit, both on separate 30Ma RCBOs:
- 6A lighting + fan + shaver point
- 15A Underfloor heating + Jucuzzi

So both can be switched off at the CU but is there a requirement for more readily accessible isolators that allow all the power to be easily switched off, or is it just a case of providing for easiy maintenance and down rated fuses on certain appliances with FCUs?

The isolator for the fan is a grey area it does not say you need an isolator but it does say separate circuits so a fault will not cause loss of safety items like lights.

Since fans do fail in real terms they do need isolators so if they do fail you can turn it off and still use lights.

I've seen the debate around isolators for fans but was wondering about other items in the bathroom.

Is isolation all about ease of maintenance then and not safety?

You must have a local double pole isolator for your underfloor heating, and you'll almost certainly want to fuse the circuit down to a level more apropriate for UFH, and I suspect the manufacturers of your jacizzi will require one for that too.

The fan manufacturers may require an isolator. Whilst it isn't an electrical regulation, it's certainly a good idea to have one, and I would fit one as standard with every fan.

The lights / shaver point do not require any isolators.

Thanks very much RF. Very helpful.
