On a domestic lighting circuit it is not uncommon to find an extractor fan, shaver point sometimes a smoke alarm or even a doorbell transformer. Just wondered what peoples' views on this is. It's the norm for extractors and shavers I know, but they are not lights so should the CU be labelled accordingly? How about if a smoke alarm is connected to a lighting circuit or door bell transformer? Where do you draw the line and at what point is it not acceptable to connect an item of current using equipment to a lighting circuit that isn't actually a light? What has provoked this question is that a client has asked me to power a wireless heating controller via the live and neutral supply from a local light switch. It's a Honeywell evo home system, so the controller doesn't switch any loads as such, just sends and receives signals. I'm not keen on the idea, but how can I justify a possible refusal to do it - if other non-lighting products are connected. He is pretty savvy, so need decent justification without looking like a knob lol!!
 
you're getting paid to do the job.just do it.nothing wrong with it, whether or not you would personally do it that way is irrelevant.

Work is tight enough why make life difficult? If i was your client i would think twice about calling you again ! sorry.
 
Nothing wrong with equipment other than lights on a lighting circuit as long as all regs are met ie overloads and disconnection times. If you are bothered that much by it you can get an 'installation notes' sticker for the c/u and you can leave comments on it such as 'heating switch powered by downstairs light circuit'

sounds like you dont need money to keep a business going , do what he asks nothing wrong with it , even leave a note at db saying its attached to lighting circuit in what room at what height etc etc :O
 
I would say check the total loads on the circuit if there not exceeding maximum capacity fine. Also agree with above comment place sticker on c/u to identify whats on the circuit you are adding to.
 
Easy solution. Run every single light, socket, fixed appliance et al on its own radial.

Anyone know if they make a 60 way CU that will fit in that cupboard under the stairs?
