as title, just been called out to a fault, 1st floor and attic conversion no lights.
arrived at the house to find as title. 1970's CU in cellar. MCB labelled cellar and upstairs lights.
cellar light working.
all cabling in cellar surface.
top of cellar stairs is a switch. T/E and 3core/E entering it.
seems like standard 2 way switch, but there's no sign of a 2nd switch for cellar.
tracing cable in cellar, T/E to cellar light, 3 core from there to switch with red as L, blue as N, yellow as S/L back to cellar light. so T/E that you'd expect to be L and S/L then feeds upstairs lights from the switch.( L& N). the 2 reds in common had been twisted ( bad practice with solid core) back in the dark ages and the L to the upstairs lights had snapped. quick strip and terminate.... lights back on. 30 minutes on site and £40 in arse pocket.... winner.
