Disconnecting central for outdoor outlets


Hello all
I need to know if this is possible we have a central air conditioner I believe it is a 2-1/2 ton which is pretty much useless (when they say it's hard to stop a trane they are right this thing all day long and still I am sweating when I get home from work).

Ok now to the question, I have a pushmatic box in the house, circuit for the unit is most likely 30 or 40 amp 220 I think.

I want to disconnect the wire outside and put a box outside with 2 15 amp breakers and 2 gfci outlets in it ( I run a lot of animated christmas lights and could use the outdoor plugs more than a useless A.C. unit.

Just looking for info if this sounds possible. I am located in Michigan.
Thanks Jerry

If the box has a 4 wire connection, you probably could, but since you are asking the question, I would not recommend you do the conversion. Basically, you need to add a subpanel to that box for proper fusing and distribution.

If you change the breakers back at the panel to a breaker set for no more than 20 amps on each side then you would not need a subpanel.

Here it is suggested that you wire nut on a short length (pigtail) of 12 gauge wire to each of the hot conductors (if larger than 12 gauge) for connecting to the breakers. This way a future owner won't arbitrarily put in a larger breaker, which is not compatible with ordinary receptacles without a subpanel in between.

You do not have a neutral run the the feeder for the A/C so you cannot run any 120 loads from it as it is currently configured.
