Electrical
All of the electrical equipment installed inside the C1D1 area will be rated for C1D1 use and UL listed; including, but not limited to: the lights, receptacles, switches, and gas detector. This means that they are sealed and/or intrinsically safe. Even in the event that the room atmosphere reaches 100% LEL or above, there is no chance of an ignition from the electrical components.
There is a single enclosure with a disconnect switch on the exterior of the module where the main power is connected. All wiring inside the module will be completed up to this enclosure, but any remotely located devices will need to be wired separately.
