Emergency Lighting Relay

[Adi]

putting elites in a warehouse, 4 rows of discharge lighting, so as to save running silly amouts of cable, was going to feed e lites through 4 relays.

Problem is when i switch mcb off, there is still voltage there although lights are off, due to control gear no doubt.

Ive not had meter on, or gone any further into looking at it, as it was late enough.

Any ideas before i go back to site?

Is enough voltage to hold relay off?

Possibly a crossed wire somewhere. I have had it where you pull the main fuse and still get 240v

Found that the live and neutral were crossed coming into the building.
