After running the compressor serval mins. the braker would trip I would reset the braker and the braker would do it again within a few mins. The distance from the panel to the receptacle is 50 feet. It is a 12-2 wireingin a metal receptacle box.

Try using a receptacle that is closer to the panel, or even a short (a lot shorter than 50'), heavy duty extension cord and if need be, a longer air hose from the compressor.

Here's a couple of thoughts.
1- Roughly the 5 Hp motor is close to 3700 watts.
2- Your circuit is for 2400 watts.
3- 12/2 solid copper wire is the right size for a 20 Amp circuit.
4- If the motor is a constant load of say 3000 Watts (30 amps)
and the circuit is running close to those limits (especially 50 ft from the panel, the line is running warm enough to trip the breaker.
5- You could find a 20 Amp circuit closer to the panel and use a heavy duty (10/3 extension cord) It should work.
6- If this is a permanent hook-up, I would put in a 30 Amp circuit (10/2 copper) with a 30 Amp breaker. New line and receptacle.

Wiring 101. What is the amp draw of the compressor. A typical 5 HORSE motor uses 760 watts per horse.Did you wire it as a 2 phase (240 volt) or a single phase (120) If you do the math,you would see that it takes a 30 amp breaker to power 4k watts.If you wired it as a 2 phase,which most heavy motors allow you wire either way,you would need a double pole 20 amp to power this.It needs to be rewired..You also have to allow for 1.5 x's the start up power to energize the capacitor to energize.Finalize,use a 10/3 NMB,so you can wire as a 2 phase.Use a 20 amp double pole breaker.I would also use a shut off box too.Make sure you use a ground wire and not rely on just the nuetral,for your ground.Make sure the ground is going to the ground bus bar too.

What length cord is coming from the 50amp breaker, and is the motor sharing a circuit with some thing else?? in accordance to NEC a pool pump must have a devoted GFCI means source presented to it. verify the plate on the pump for amperage. 12awg is solid for 20amps. If more advantageous that 100' from means source you've voltage drop and cord desire volume 10awg cord(even if that's 15-18 amps). Is there a subpanel out on the pool section which could have breakers for pump lighting fixtures fixtures,etc. If no longer and volume 12 cord is feeding that fifty amp certainly replace with 20 amp. also, the pool body and pump must be bonded with #8 bare copper cord, no longer 12/2...

the air compressor id pulling more that a 20 will hold , technical it is never getting out of lock rotor or start , so the amps are higher put a 30 in there , Don;t try it on an extension cord , it will not like that either
