    Good morning all,

    I would like to install a Bathroom cabinet that has a shaver socket and light from scratch.

    I am quite comfortable with IEEE Bathroom Zones.

    I would like any relevant advice regarding this task but specifically the supply (ring main or lighting circuit?) and do I need an isolating fuze.

    Thank you

    Lighting circuit is more normal, and no need for an FCU. Is yours RCD protected?

    IEEE is an American organisation. I think that you mean what was called the IEE, now called the IET?

    The cost of Part P notification last time I looked started at £100 plus vat plus inspection and testing unless you can prove to the LABC you have the ability in real terms means you need to find a scheme member electrician.

    The use of a fused connection unit is down to what happens if it goes wrong. Would the loss of lighting cause a danger, and would even a 1A fuse stop the loss of lighting if taken from the lighting supply. Taken from a socket supply if the supply to the socket is 16A or under than does not need a FCU, if over 16A then it does.

    In real terms consider what happens if the unit gets damaged. Normal is to remove it then replace, but to remove you need to remove the supply, easy way to remove supply is to lock off the FCU. Be it a cooker connection unit, a FCU, or a clock supply unit, you really need some easy way to remove in the future.

    Thank you for your comments thus far.

    I have fat fingers and put too many E's in IEE which is now irrelevant because it is now IET. So yet again I have learned something new.

    I will be having a new consumer box fitted in the near future so all circuits will be RCD protected.

    Essentially I am laying the cables in preparation for receiving the Bathroom cabinet and want to make sure that I have everything in place before I tile the walls.

    If the lights fail in the bathroom I can't see a problem. It's a small bathroom and there would be plenty of residual light from the hallway.

    If the bathroom cabinet needed replacing it could be isolated by the RCD on the consumer unit.

    Have I addressed your concerns and are we saying the supply should come from the lighting circuit?

    Thanks again.

    Ideally you should have the CU replaced first, because otherwise you'll be non-compliant with the new buried cable not having RCD protection.

    As for failure/isolation - I wonder how many people who see that as a concern have all of their lights throughout their house on individual isolators in case they fail.

    Thanks again for the info.

    My old CU is RCD. I will be having a new CU because I have additional circuits for new bedrooms my roof.

    Once again can I draw you to the question of supply. Is there any difference wether the supply is either ring main or lighting circuit? I would like to choose the easier option whichever that is when I lift the floor to access the wiring.

    Thanks again.

    It's a light. It should be on a lighting circuit.

    I agree with Winston (Shock, horror). Powering it from the lighting circuit will mean that an intermediate fuse is not needed - subject to the makers instructions.
    If you take the feed from a ring final circuit then you would need to find somewhere to install a fused connection unit, and you can't bury that under the floor!

    Hi Winston thanks for your input.

    The cabinet has both a light and a shaver socket.

    I would happily add it to the lighting circuit if it was just a light. It is the shaver socket that is causing me the confusion.

    Can I have a shaver socket on a lighting circuit and are the any additional requirements if I do?

    Thanks

    99% of the shaver sockets in the UK are on the lighting circuit. They are usually only about 20watts - so less than your average lamp.

    So no problems, press on.

    You can supply it from either, if from a ring I would use a FCU. What I was noting was you live in Wales and your having building work done likely the LACB will be involved as it does not cost much to all electrics to the list. It would seem main problem with Part P is the minimum charge, if it is bundled with other items you are not worried about the minimum charge. But to comply you must notify first. Not after it is done.

    The LABC with me in Flintshire were not very keen on me doing my own inspection and testing but they did allow me to do it in the end. It they don't allow you to inspect and test in the main they want a electrician on their list to do it. Remember in Wales there is no third party inspecting and testing. It is easy to exceed the cost of installation with the cost of Part P compliance, so it may be better not to DIY specially as the LABC inspector will be visiting for the other work.

    There are no charges associated with Part P:

    Not complying with Part P is not an option, whatever it costs to make reasonable provision in the design and installation of electrical installations in order to protect persons operating, maintaining or altering the installations from fire or injury, that's what it costs.

    For clarification. BAS is correct. There are no charges associated with Part P.
    But there are costs associated with the process of notifying the work.

    BAS is being pedantic yes the Part P law covers all work as he states, but the bathroom in Wales is a special location, so there is a requirement to notify the LABC. When one breaks the law, one clearly hopes one does not get caught, since you are having other work done, which it would seem will also need notifying, then there is a high risk of getting caught. One may do 35 MPH in a 30 limit, but not when you know there is a speed camera.
