50V at lighting point when switch off
Hey guys, apprentice here that can't get my head around a fault we came across today.
When testing for voltage at plug bases with the switch in the off position. Reading 50V Active to Earth, 50V active to neutal, 0V earth neutral.
Jumps up to 230V when switched on.
The fault is only in some of the room, not all.
Originally thought it could be a broken neutral but that doesn't explain 50V active to earth.
Thanks you the help.
