I bought a used Energair 2, 80 gallnon 2-stage air compressor. I tried to wire it to the breaker box. I, also, installed a throw switch box, in line, to use to start it, rather than flipping the breaker all the time. It also came with a control box, which has a reset button on the front. The wires from the pressure switch on the tank are also wired into the control box. All it does now is blows the fuses in the throw switch. What is wrong???????

If the unloading valve trips , which i think is the safety valve that tells me the compressor is pumping up past its maximum allowed pressure. that black switch should be the overload switch. check the amps of the wires going to the motor while its running and then look at the name plate of the motor to see the maximum amount of amps that the motor is allowed to draw.

half the wires go on one side and the motor wires on the other, ther are letters next to the terminals look it up on google to what wire goes were, but most i had delt with is motor cord is on the side away form it and the wires go red top blue/brown/black on bottem then green on the other corner of the same side then on the other side of the switch goes the same for the main power cord

If you ran the wire 120 feet you should have ran #8 wire instead of #10. The long distance you ran this requires that you run heavier wire than needed for a short run. You are loosing power and more than likely do not have the proper voltage/amps at the compressor due to the resistance of the wore on a long run as this. On this long of a run you always go down one size in the wire you use. I am assuming you connected the wires correctly at the disconnect. It is easy to get the line and load mixed up. On some disconnects the inner 2 are line and on others the inner 2 are load. Look carefully to be sure you have it connected right. On a 240 volt circuit the Black and white are connected from the breaker box to the line lugs on the disconnect box and the compressor power wires are connected to the load lugs. The ground wires are connected to the ground lug. In addition have you looked in the owner's manual to see exactly what the amps are for this unit? I assume you have but I must ask. If you have everything connected correctly and it does require a 30 amp beaker then the long run of #10 wire has to be the problem assuming there is nothing wrong with the compressor itself. Might be a good idea to check it at another 240 volt power source to be sure.

all depends on voltage, horse power of the motor, and single phase or three phase,,, must know that to give you an answer.

SOURCE: compressor starts innitially,then when pressure

the start capacitor on the motor body is weak,the motor needs this component to over come the air pressure when cycling to re-build the low air pressure,change both the start and run capacitors when doing the start because the other run capacitor is just as old and it will soon fail
