    120 To 240
    I have a 100 AMP Pushmatic breaker box in my garage. It is full of breakers that are all 120 volt that ranger from 15 to 30 amp. I want to hook up a 240 amp for a pump motor and a one for a welder. Can I hook up two of the 30 amp 120 volt breaker to accomplish this with each one?

    As a temporary measure sure, but should not leave it as is indefinitely, as if there is a short or overload, only one pole will trip leaving the other pole on. Or worse if someone uses the breaker as a disconnect and mistakenly only shuts one pole off.

    ITE Bullgog PushMatic breakers are still available, hard to find but they are out there.

    These panels are a bit unique in that one leg is one entire side, and the other leg is the other side. If you have any 2 pole breakers you can see the each pole sits across the bars to connect to each leg to derive 240 volts.

Replacing a 240 volt outlet with a 120 volt oulet [ 1 Answers ]

We've switched to a central air conditioning system and no longer need the 240 volt outlet by the dining room window. The house was built in 1928, updated in 1957, and again a couple of ad hoc times thereafter. The wiring is at times very old, brand new or somewhat old. My guess is that the 240...
