shaver socket outlets

[i=p/u]

we just nearly finished kitchen rewire for guy and he asking all sorts of other we jobs, done.

my question is this we only rewired kitchen and fitted new board with 30mA rcds. he is now asking about shaver sockets in two bathrooms... would these need to be rcd protected or could i just come off the lights..??
as these are selv

The best and most compliant method is to protect all the circuits in the bathroom with an RCD when you are making changes.
If you have just the one lighting circuit that is currently on a non RCD protected way in the CU and can move this cable from non RCD protected to an RCD protected MCB, then this is very easy (even if you need to extend the cable a bit). simple and straight forward compliance. There should be no need to run another cable from the CU to the switch, Just move the existing cable over in the CU.

im scared what lurks beneath that rats nest of cables. for lighting. but yea

should of said its an old 3036 board which has been added to alot over the years.

theres 8 velux windows and god knows where they are all tapped off..

 

[Richard Burns]

Yeah, I know what you mean, can be a right mess some units.
Just take out the lighting line conductor and give it a tug and see which neutrals and cpcs move!! Just hope more cables don't pop out!
Disconnect those and see if there is any give on the cable then just tuck it all back at the point you need.

punjanna anyone. morning

Ahh, just realised you have one 3036 board and your new board for the kitchen, so you will need to extend the cable. Just disconnect it and get it accessible, crimp on a new length of cable, and feed this back out of the old box and over to the new CU, not ideal but if the old cable entry is not accessible this can be done.

If it is easy to feed a new cable to a point where you can reach the old wiring coming down then you could crimp / heat shrink on there and pull out the old section.

ok cheers. just love to get into the fram of mind to tackle it, all good. lets say i was to replace the cu with dual rcd board for rest of house... what would be key things to look out for.. i dont think would be borrowed neutrals as is bungalow, but you never know.. this is an option..

Yes you need to RCD the lights as well, as soon as you modify the existing bathroom installation it must comply with the current BS7671:2008 ... in #8 I emphasised 701.411.3.3 says "ALL CIRCUITS OF THE LOCATION"

 

[i=p/u]

maybe pir to identify every circuit and where each accessory is comming from...??

 

[Richard Burns]

Changing a CU from no RCD to RCD first thing is neutral earth connections that would not show up in the old board, do an IR between N and E bars, then start the fun of narrowing it down.

sorry markie sparkie... im just storming with myself here..

 

[Richard Burns]

PIR is recommended and makes things much easier.
But will the customer pay for it!!
