I have a 26 year old, rusted to hell, dog ugly, and likely dangerous Federal Pacific AC disconnect with a non-fused 60A breaker.
What I would like to do is replace this disconnect panel with 100 amp 6 space exterior panel with a 60A breaker for the AC, and use one of the other spaces for a 20A GFI protected 110 circuit.
That circuit is dedicated for the AC condensing unit only. If you look closely at the wire inside the disconnect you'll probably find a 10-2 with ground. As others have stated a neutral is not present for the
110. If you look in the main service panel you'll also probably find that it's on a 30 amp breaker. The 60 amp disconnect is a disconnect only. It's a common installation. In other words, you can't do what you propose. One solution would be to come out the back of an interior outlet in that area or, preferably, run a new circuit.
Reply to cover all the questions........ The main service panel was a 200A FPE with Stab-Lok's when we bought the home. It was instantly replaced with a 200A Square D Homeline series, BEFORE I would sleep in the house. Replaced the meter enclosure at the same time.
I have also gone thru the entire house and swapped out all of the switches, receptacles, lighting fixtures, cleaned all connections, and used fresh wire nuts. The available junctions boxes have also been opened, inspected, and fresh connections made. All receptacles now test correctly for proper ground and neutral.
Oddly enough.... This entire home is wired with 12 ga., not a strand of 14 to be found. Someone must have had a stack of 12 ga. in stock, or the original builder was a bit twisted. They went to a lot of extra work as a result. (no back stab connections)
The wire to the AC disconnect is in fact 10-2 with ground, no neutral..... I'll just replace the disconnect, and waterproof conduit to the unit. Going for a new circuit for the 110. Thank y'all
