lighting circuits - just for lights????

[jedisparks]

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!!

don't think you get it mate, nevermind

i get it , your a bit ott in domestic electrical wiring

True... but if the lights trip you have no smokes ( well... running of battery)

exactly then urging a repair asap

But if the smokes are on its own circuit. You will still have your lights on.... all yourl have is an annoying beep from the smokes

what if the non spark occupier takes battery out

what if the non spark occupier takes battery out

when the house burns down, then gets rebuilt, you get the job for wiring it

lol supose

They shouldnt take the batt out. Lol well you just got to hope they dont anyway

another solution smokes on own circuit with 1 light on it aswell mybe the light nearest db i.e outside electrical cupboard

From the OP:-

"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?"

A. Anything you want or need to feed from the circuit in question. Long as the MCB and cable can handle the load of which your introducing.

There is no such thing as a "lighting circuit" or "socket circuit", they are all circuits that was designed to function as a lighting or socket circuit at first and then through later design, calculations and installment became a circuit that feeds more than one type of load.

Q. Can the cable, MCB/RCD handle the new load? Is the cable the same size? no need for a fcu then. What is the total load at the moment and what will you introduce onto it?

Exactly, and well put. A final circuit that serves lighting or power outlet accessed by 13A sockets does do not automatically become 'exclusive' lighting or socket circuits.

Thanks again Paul.

Volts mate, you really need to sort out your "quote from post". LOL

But thanks

Smart..... we finally agree haha

Volts, you can always do stuff like this:-

Very nice lol. Bit in ya face though haha

Voltz is one of my many forum friends + we speak to each other now and again. No insult intended and he will not see it that way, trust me.

Ive been away from the forum for a short while and its nice to come back to welcoming friends

Wasnt saying you was insulting him in ya face with the colours lol
