So I am at a job right now to fit downlights in a bathroom (I tried to talk her out of it), and have easy access via loft above. Isolated upstairs lighting circuit. Wiring in loft is very neat, there is a Line enclosure present, all cables neatly clipped. However, on inspection I have found that inside the Line enclosure there are three different circuits, lighting, ring final and smokes. I wouldn't dream of doing this.....would you??

Nothing wrong with it.... What happens when you move a DB and mount an enclosure full of DIN rail connectors. I think the most circuits I have had in an enclosure is 30 odd.

This was going to be my post,but I read yours before hitting the button :sailor:

How often on here do we read that a consumer unit is to be changed which will require extended circuits,the solution presented is an adaptable box to extend the various circuits enclosed in that junction box

but in kingeri's case, where this is in an attic, he isolates the lighting to work on that circuit and then to be safe, he needs to isolate other circuits as well. i think they need separating, even if not against regs.

Nothing "wrong" with this as such. But you should label it as requiring more than one point of isolation before opening. Put a label on the CU too.

I've seen something similar in a bungalow where the Cu had been moved out the kitchen to the hall and all the circuits needed extending. The standard of workmanship was very poor in that case.

A consumer unit is an enclosure and that has multiple circuits? I don't see a problem, if it was on different phases though I would use a 400v sticker on enclosure cover.

there' s a bit of difference here. when you open a CU, you expect multiple circuits. when you open a line enclosure in an attic, you don't.

I was thinking line connector as in Line connectors ...our forum sponsor, never used them but are they capable of taking RFC. Light circuits and FA in one fittings?

Not really, you shouldn't assume because it's enclosure that it has one circuit either. What about switches? Quite often they have multiple circuits..
