Question:
Hello CQD,
I would like your opinion on this question. New car dealership with service garage, offices and showroom. The service garage is separated from offices and showroom and showroom has six cars in it with sales desks and chairs close by. There are about ten 120v floor outlets throughout. Would you consider the showroom as classified or unclassified, Class 1 Div. 1 or 2 and outlets 18” minimum? I’m told NEC 511.2 and Table 511.3 and Table 511.3 is only to areas where fluids are handled or transferred.
Thank you very much for your time.

Hello Patrick,
Your thinking is correct. Based on the information in the question and the text in Section 511.2 (minor repair garage) and Section 511.3 and Table 511.3(C), the showroom would generally not be a Hazardous (Classified) location. On situations such as this, and since we cannot see all conditions that need to be assessed, we strongly advise that you consult with the local authority having jurisdiction for the interpretation and associated approvals.
