 |  "Correct Wiring?"
, posted Mon 30 Jun 16:14  
I will be wiring for a new Carrier 21 SEER AC system as I do not have the space to put the condensing unit where my current one is located.
System needs a 50 amp max load (will be using a 50amp double pole breaker).
Would 6/2# NMB wire (with bare copper ground) be okay? The wire will be run in the attic (approx 70 ft) and run in conduit (rubber liquid tight) on each side of the house (10 ft each) - one to the disconnect box and the other to the breaker panel. So, 90 ft run in total.
I could not run the wire down the inside wall to the breaker panel from the attic, so I had to run it outside under the soffet in the conduit - drilled a hole in the brick wall just on the other side of where the breaker panel is located and routed the wire through the hole (put a junction box just outside the hole).
By the way...I live in Texas where my attic temp gets around 120 degrees during two months in the summer.
