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.
The good conscientious technician or serviceperson will carry extra oils and lubricants in case the new pump did not come with oil or the oil was accidentally spilled, so the service call can be completed without an extra visit.

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.
