Cooler Control panel

[transman2]

Is there a code requirement for the outdoor compresser and the indoor Fan coil being on seperate breakers.

I have a homemade control panel tht has a Main breaker that feeds a contactor with overloads for the inside fan unit and also parelels off the load side and feeds a breaker for the outdoor unit that has no contactor.

I'm used to seeing a main that feeds 2 breakers, 1 for the inside unit and 2 for the outdoor unit in the control panel. Each having its on contactors and overloads.

Does anyone know if this violates any codes.

Also I was checking the thermal overload and it would only open if you held the test butten in, if you let it go the contactor would close again. Acting like a momemtary switch. Most overloads I've tested in the past you can test it and will open and it wont close until you hit the reset button. This unit does have a reset button. Does anyone know if theres an overload that works like this.

Depends.... Most are seperate equipment and the OCP sized and limited to each - but due to size of the unit - the limits of the OCP size may not be able to handle the combined load. If that makes any sense? But some smaller units - the OCP may be able to handle both, and even control the other "through" the first by contactors at the compressor location.

Most IEC overloads and some NEMA electronic overloads have a hand/auto reset selector. The one you are questioning is probably set for automatic reset function.
