upstairs and downstairs lighting circuits in one switch coding

[7029 dave]

it is yes

Sounds very much like a borrowed neutral to me?, what code would you give.?

 

[deanmac]

no borrowed neutral both lighting circuits on alternate rcd's no tripping

2 gang 2 way hall and landing lights

That's good, just old 2way set ups are wired that way live bridged across from common to common off downstairs circuit.

do youmean on the same switch, or 2 circuits in the same enclosure?

 

[deanmac]

the lght at the bottom of the stairs is on down lights the light at top of stairs is on up lights,both switched from 2 gang switch,i would have had the bottom light on with up lights or vica versa

Depends on who and what light was last switched, to ascertain the position of the switch dolly one of them would be a 2 way wouldn't it??????????

 

[deanmac]

???? when you turn off down lights the light at bottom of stairs goes off,while 2 way light at top of stairs stays on,hence 2 circuits from same two gang switch at bottom of stairs

Not a problem then. it's been that way for yonks.

 

[deanmac]

don't you agree it should have been wired the way i mentioned

Nothing wrong with having two Lives at a light switch, just make sure that it is marked up on the CU "upstairs lights, downstairs lights". If the next person is working on the upstairs ceiling rose, guess what MCB he needs to turn off??? If working on the light switch he needs to turn off both!

I install up and down stairs hallway lights separate as standard, have done for ages. Never had any problems.

As the regs covers domestic, commercial and Industrial and the same regs are applicable to all 3 then those isolated to domestic work only, often do query such set-ups when they first come across them, in commercial and industrial world it is common for different phases to be present in one bank on switches, this is common practice and as no voltage to earth exceeds 230v then no labling required.

As already mentioned, safe Isolation and confirmation using appropriate testers would mean that there isn't any inherent risk in this method and as we are not here to argue Darwins theory of natural selection, I don't see anything wrong with multiple circuits or phases in the same switch.

Could you just imagine the visual "looks" of 2 side by side 1G switches in all our houses if you can't have 2 circuits in 1 enclosure.

If muppets can't work out to isolate both circuits, they shouldn't be undoing the screws!

And some muppets need a warning/caution sign for everything theses days



(now does the above paint a mental picture for you????) :rofl: I bet some people have tried it?

 

[deanmac]

there would be need for 2 x 1 gang switches side by side as you mentioned it was wired correctly in the first place
