Industrial Lighting

Is it permissable to use a plug and receptacle hook-up on 400W or 1000W High Intensity discharge 480V single phase lighting fixtures, fed through a remote contactor? The contactor will be fed with a 3 phase 480 volt delta power source from a busway with a high impedence ground. There will be about 54 lights fed off of the remote contactor. We are an Ohio manufacturing plant.

Re: Industrial Lighting

Thanks David, we are also wondering if each luminaire has to have its own seperate fuse protection, and what is the minimum cord size and rating?
