Is it acceptable to have: upstairs lighting radial and downstairs radial.. (Forget this bit its just for info - as I know thats acceptable!)
Say downstairs hall light (bottom of stairs) 2/3 way lighting (downstairs), and the 2nd or 3rd switch at top of stairs to turn this off...
Stairs and upperlanding light switch in same patress as above's upstairs switch and a 2way switch downstairs in the aboves patress on the gnd floor.
This just means that 2 patresses will be effectively fed from both upstairs and downstairs breakers.
The reason for having 2 radials is due to spot lights and a future extension.
