Adding a loft light and switch
Posted: Mon Jul 12, 2021 3:41 pm
Good evening, I have a few questions regarding how to add a loft light from an existing circuit and I will do my best explain what I know so far and I have attempted to show it by using a paint and attaching it, so apologises for my bad drawing in advance, also not sure how to get the paint image to show full size sorry)
The upstairs house lights appear to be wired live to the switch and then a switched live to the ceiling rose, with a neutral run from ceiling rose to ceiling rose and the neutral appears to just end at the landing light.
( the live for the next switch is taken from the previous one and so on. It's a house built mid 1960's and guess it was wired thus to save on cable costs.)
I have easy access to all wiring more or less, only bar two ceiling roses, as access to the eaves is boarded from the main loft area and I have to get through a small cut out.
I have three questions really:
1: In order to add a loft light with it's own switch, is possible to simply cut the live to bathroom switch (last live is wired to this), add a junction box for live to the new loft light switch, switched live from the switch to new light fitting and run a neutral from the landing ceiling rose to the new light fitting?
2: Is it normal for the neutral to simple just end at the last light fitting?
3: And lastly is it ok for the landing light to have the neutral as it is, as it's live is run from a 2 way switch in the hall downstairs, so should it not take it's neutral from the downstairs also?
( I would like to just mention that apart from one cable which is twin & earth (landing light switch live), the wires in use are double insulated single core for neutral and double insulated single core and earth for the live and switched live. Old black & red colours)
Any help/advice would be greatly appreciated, and apologises if I have explained things poorly. Many thanks for your time.
