Hi. I want to put a light with fan in a bedroom but on removing the existing fitting it turns out that there is no permanent live. Having looked at the switch it has been looped through that.
My question is can i tap in to a permanent live from the same circuit in the loft?
My head is having a problem with terminating the Neutral at the fitting,as in the Neutral extension being terminated at both ends. Hope this makes sense. Many thanks. Steve
You wrote "I want to put a light with fan in a bedroom"
"on removing the existing fitting it turns out that there is no permanent live" - Probably, the existing light fitting in the ceiling has only a "switched line connection" and a Neutral return conductor.
"Having looked at the switch it has been looped through that.
" by which you probably mean that the "Line" connection goes to the switch and is then switched to energise the light fitting, with that fitting having an available Neutral (return circuit) connection.
You then wrote, "My question is can i tap in to a permanent live from the same circuit in the loft."
One must wonder why you would wish to do that.
If you have a ceiling light which works as you have 'explained", you have a "Line" connection available at the switch for the existing ceiling light.
If you wish to operate a ceiling light/fan combination from the existing wall switch box, all that you need is another "switched" conductor from the wall switch location to the ceiling light/fan location, with the new conductor providing current for the fan.
The "return" current will be via the existing "Neutral" conductor for the existing light fitting.
Good Luck.
