The interpretation of the term "heating panel" is currently under question in a situation I am involved with. According to NEC 427.22, "Ground-fault protection of equipment shall be provided for electric heat tracing and heating panels." The exception listed after that sentence does not apply in this situation.
The situation is that there is an electrical distribution panel at a biodiesel fuel storage site which provides power to tank heaters for the biodiesel tanks. There is no heat tracing on the pipelines anywhere in the facility, just heaters that go into a well into the tank to keep the biodiesel fuel at the proper temperature. The owner of the facility is questioning whether or not ground fault protection is needed at this tank heater panel.
So, would the "heating panels" referred to in this code section apply here? :-?The "electric heat tracing" does not apply to this situation, so if "heating panel" does not either, they would not need the ground fault protection. If you need more information on the heating panels in order to answer the question, please let me know what is needed.
Thank you for your prompt help!
