    Breaker Tripping
    I have a eight door commercial cooler that uses a outdoor a/c unit as a compressor. The compressor was just changed. But now the breaker trips after about 8-10 hours of use. The unit runs on 220 current.

    Please... what do I do.

    I separated your question to be alone from the thread you originally replied to.

    Need to know more detail on the cooler, such as amperage, voltage, etc. This can be found on the nameplate on the unit.

    Also need to know the size circuit breaker that is tripping.

    I have a eight door commercial cooler that uses a outdoor a/c unit as a compressor. The compressor was just changed. But now the breaker trips after about 8-10 hours of use. The unit runs on 220 current. The a/c model # is NA360AKB200. The compressor is 208-230 volts 60 hz max fuse is 30amps.

    The breaker that is tripping is a 30amp double pole.

    Please... what do I do.
