Just returned from a job, for certain reasons the job will be passed on to another contracter tommorrow.
Theres 4 rooms tripping an mcb
each room has 1 centre light, they appeared to be 2d though unsure if they were the originals.
However the rooms had 2 way switches, each switch appeared to have many 3 core cables.
there was no second switch in the rooms.
L1 had a Black and a Grey cable
L2 had a Brown, another Brown and another I think was Black
Com had a Black and a Grey cable
So possibly 7 wires in each switch
Just wondering why so many cables, they had used RED rocker switches, only thing I can think is possibly a Second perhaps emergency supply that puts the lights on, even though the switch is off.
It was a care home/ hospital envirement.
Any ideas
