A friend has a barn, the supply is fed from his house into a DB in the barn, (not sure if fed straight from the incoming supply in his house, or fed from a way in his DB board in his house)
He has LED floodlights (450w) x 10 in his field, fed from a way in his DB in the barn.
When he has over 6 of the floodlights on, the induction hob in his home, fed from his house DB is flickering on and off.
Has anyone got any clues as to why this is happening?
The barn has a TT earth setup.
