Air Cond Unit disconnect switch?
Installing a 4-ton condensing unit outside (240V, 1 ph, MCA= 26A, MOP= 45A). There will be a HVACR rated 45A breaker at the panel. Plan to install the 60A non-fused disconnect with GFCI recepticle (GE U065NA1010) next to condensing unit. Plan to use #8 wire since distance from panel is 80 feet, but unsure of the number of wires. How many conductors will be required since the disconnect will have a 120V GFCI recepticle. Will I need 2 wires (2 hots and 1 ground) or 3 wires (2 hots, 1 neutral, 1 ground)? I'm thinking #8 wire with 3 conductors (2 hots, 1 neutral, 1 ground).
