shaver socket from lighting citcuit

[peterpedroreid]

i am wanting to install shaver socket in bathroom, i under stand you can take it from the lighting circuit but must be earthed,

does this mean you can take it directly from the Light switch from the L, N and Earth to the shaver socket, the shaver socket i have has built in transformer.

Any help would be greatly appreciated

No.And it is notifiable work

To expand:

No, because the Neutral at the light switch is not a Neutral at all, it's a switched live to feed the light. Connecting the shaver socket in the way you describe would place it in series with the light when the light was switched off (the socket would probably work if the lamp is a standard fillament lamp) and the switch would short out the power to the socket when the light was on (the light would work, the socket would not). The shaver socket would also not work if the lamp was removed or blew. A dangerous side-effect would be that the light socket would be live even when the light was off!

You should take the feed from the loop in/out terminals in the ceiling rose. But as previously stated, this is notifiable work so it would almost certainly be cheaper to get it done by a professional electrician who is an a Part-P scheme.
