Class 1, Division 2 receptacles???
Class 1, Division 2 receptacles???
(OP)
I am currently on a project which is an Electric Golf Cart Charging Building. The area has been designated as a Class 1, Division 2, Group B location. The receptacles for the chargers are ceiling mount (12' AFF) Nema 5-15R (regular receptacles). Would these receptacles be acceptable for this location?

I'm not positive, but I "think" the NEMA 5-15 receptacle is fine (although I would suggest twist lock type receptacles 12' AFF), but you need to insure the conduits are sealed properly between hazardoud/non-hazardous areas and any j-boxes/faceplates are rated for hazardous areas.

I have seen many forklift charging installations and none of the area is wired as if it is classified however these areas tend to have permanently open areas from which the gas will vent. I once did a golf cart charging system where the golf carts were charged underground, underneath the pro (golf) shop. There was no direct way to vent upwards so I installed mechanical ventilation with an airflow switch. Lack of airflow would shunt trip the charging equipment. It had typical time delays both for startup and shut down. You could also install a hydrogen combustible gas detector.
If any part of the installation would be considered a classified location it would seem like the ceiling would be since that is where the hydrogen would collect.

I assume in CTSparks case, as in mine, the chargers are in another area.

A little confusion here. First, this is shipboard, so NEC doesn't apply.
After re-reading, you are right, OPs receptacles are for the charger. At first read I was thinking it is the battery connection receptacle. I am too accustomed to hard wired chagers and battery banks.
My space with the permanent battery bank doesn't have any receptacles. The spaces with the receptacles are very large cargo holds, where non-commercial vehicles are loaded and stored, with fuel in their tanks. When the hold is environmentally sealed up,it is treated as class 1 div 2 group D, due to possible fuel leaks and vented tank caps. When all our vent systems are turned on (a couple thousand kW), it isn't classified. So if the crew needs to work on the vehicles,and needs a receptacle, they can fire up all the fans to energize the receptacles. We did need to work with Regulatory Bodies to get approval. It was difficult to get that approval, but I understand may not even be possible in NEC etc world.
