GFCI for roof and gutter heaters


I was told that a roof and gutter heater receptacle doesn't have to be on a gfci. It is considered to high for a person to normally reach it. WTH!
I am in articles 422 and 426 and I am lost. My head hurts.

You were told correctly. Here is the Exception: Receptacles that are not readily accessible and supplied from a dedicated branch circuit for electric snow melting or de-icing equipment shall be permitted to be installed in accordance with the applicable provisions of Article 426.

I already have it on a GFCI breaker. Article 426.28 ? I have no idea what the tenant will do with the heater or receptacle.
I can just see a DIY tenant up there with an ax helping the heater cable because it wasn't turned on.

Personally I would want heat tapes in a metallic gutter protected by GFCI. If you were to have a fault, the whole gutter system could be come live. Walk by and touch a downspout and OUCH! (or worse).

I believe that those outlets are allowed to be protected with a GFEP breaker, which is a different animal than a GFCI breaker.

GFEP is for equipment protection and has a trip threshold of 30 mA. A GFCI breaker has a trip threshold of 5 mA, and is for personnel protection.
