Although if you are supplying the smoke alarms from an existing circuit it's not notifiable, for something as life saving as Smoke Alarms, I would advise you use 3 Core and Earth cable and have the circuit tested by a qualified electrician.
I wouldn't put the upstairs lights and sockets on the same RCD, as if the upstairs sockets trip the lights go out too! And which floor is the shower on? I'd put the Upstairs lights on an RCBO on the unprotected side.
I think the bloke who offered you the job is taking the **** a little. I would be asking if his company is Part P registered. If not he should at least pay the registration fee. It's worth speaking to a ELECSA regarding a Defined Scope assesment as appossed to a Full Scope one.
I agree that interlocked switched socket outlets would be best. You don't want customers just plugging anything in. RCBOs would reduce loss of business if a bed developes a fault.
If you can't physically see the bond to the Water, your best bet is to put an earth clamp within 600mm of the main stop cock and run 10mm back to the main earth terminal. It maybe that it is currently earthing through boiler pipework.
Maybe your message wasn't relayed properly to the council electrician and he thought you were going to put an RCD in as a main switch, which if it nuisance tripped could lead to 'black outs'.
As all three colours are technically a phase/Live colour as long as you sleeve at both ends which you've used for which I don't see it really matters. I've always been taught to use brown as live, Black with blue sleeve as Neutral and Grey with brown sleeve as interlink. This gives some...
I've done a new build recently and when I measured the socket height of an exisitng worktop to get an idea the top of the socket was 1200mm from the floor. This is a high as you can go on a brand new install.
A slightly cheaper alternative that would help keep inline with the regs is to put the lights on an RCBO and the rest on a seperate 30ma RCD. At least that way the lights will stay on if the sockets or immersion trip the RCD.
Some capping nails are bettet than others. I think the best ones I've used were made by Thorsman (available from discount electrical - although they make take some time to arrive) Screw and plug with a big washer on the screw should hold the capping on nicely.
Might be an idea (if you feel confident enough - and if you don't get a spark to do it) Install a Switched Fused Connection unit (could be an RCD one if you like) supplied directly from feed to the single socket and install 4 wall mounted double sockets fed from the Switched Fused connection...
This could be done with 2 contactors. Run Twin and earth from each of the light fittings connecting the switched live and neutral to the coil of each contactor separately. Then supply the fan on a seperate circuit from the consumer unit and daisy chain the live and switched live for the fan to...
Hi, Anyone remember the Rotaplug? I got one for a present back in the 80s but it's disappeared since.
It was a great plug that you just cut all the wires to the same length, stripped the insulation off stuffed the ends in and turned the centre of it round 90 degress and it locked the wires...
