Neutral at light switch

[Spoon]

I had the floor boards up today looking at the lighting circuit and notice the feed from the CU went to a junction box and each room downstairs was fed via this junction box. Never seen it done like that before. Always either feeds in and out at switch or at ceiling rose. Is it ok this way?

If the junction box is 'maintenance free' then it's ok.

Could always use these if you wanted to change them.

Yeah, the junction box method was quite common when I was an apprentice but electricians soon realised that these junction boxes hidden under floorboards were hard to get to when it came to fault finding in the future, hence the reason why nowadays the loop-in ceiling rose is the preferred method.

I hate junction boxes and they shouldn't be used unless there's absolutely no way round it.

I'm sure there will be some one in their seventies along soon to tell me different.
Back in the good old days, during the WAR.

The junction box method was commonly known as two plate because ignoring cpcs the batten holder plate only had two terminals. Later this changed when loop-in terminals were introduced giving roses and battens three terminals to the plate hence, three plate.

See I said one would be along shortly.

Doesn’t have to be maintenance free, as long as it’s accessible.

I know lifting a carpet and floorboards is hardly “accessible” but that’s not the definition.

If you’re in the box anyway, you may as we’ll redo the joints with Wagos anyway. If the wiring hasn’t been touched before, there will be one big “pudding” joint as they say up here. One for live, one for neutral and switch wires running through the box, no joints.

IMO under floorboards is not 'accessible' hence my post #16.

Not accessible in todays wall to wall carpets and laminate flooring... but when they were first used it would be roll back the rug and just a screwdriver to lift a short board.
Nowadays we don't fit junction boxes if we can help it, but where we do they are MF just for ease of installation..... accessible or not
