We have a piece of equipment that was originally purchased and designed for use in an X-proof environment.

It presently has been re-purposed for use in a general purpose environment for general purpose processes (non-hazardous).

Can we use general purpose electrical components ( disconnect and motor starter) as a power feed to the unit or do we have to maintain the X-proof rating for the new electrical components in the new area.
