Often, on a construction site, the inspector is asked by the electrician if the inspection department will require hazardous location wiring methods for a project and if so, how will the area be classified?

These types of questions are more suited for the design engineer responsible for the overall project. The engineer designs the project for the owner based on the owner’s needs and how the owner plans to use the building.

Once the hazardous locations on a project have been determined, the inspection authority is then responsible for inspecting the project according to any required wiring methods specified in the appropriate code section for the type of hazardous location.

Refer to the Laws, Rules and Wiring Standards of North Dakota for additional rules pertaining to the determination of hazardous locations.
