I have heat trace branch circuit 277V single phase. Breaker should be single pole off of three phase 480/277V panelboard. However plan designer says their is no manufacturer that provides single pole GFPE breaker 277V. So he decided to use two poles breaker that comes GFPE and going to use one pole for circuit of heat trace leaving the other pole no circuit.
Questions:
1. Can you use only one pole of breaker that has two poles has GFPE? Code allow?
2. Is their really no GFPE 277V, single pole breaker out their?
