3hp compressor ! Can it be run of a standard extention cable

I am thinking about starting my own business up sandblasting & spraying' but need a portable compressor that will be able to give me not just the power but the freedom to take it any-where .


Please is there any-one how could help me with my dilemma.

No dilemma, Barry. And no, do not run your air compressor with a standard extension cord.

Rather than using an extension cord that could, and probably would, under power the compressor, consider using longer and bigger I.D. air lines to bring the air to the tools where you want to use them.

If you must use an electrical extension, I wouldn't go over 25' in length, and I would not use smaller than a 12 gauge wire.

HOW TO REPLACE THE 120 VOLT MOTOR TO 220 VOLT 50 HZ

by AGNELO

WE HAVE COMPRESSOR SPEED AIR 4B222 CAN WE CHANGE THE MOTOR OF 120 VOLT TO 220 VOLT WHICH IS THAT MOTOR

Agnelo, as long as a new motor fits the mounts, has the same size motor shaft, and can interface with the compressor pump properly, then as far as I am concerned, the pump does not care what motor is running it.

If you wish to replace your 120 volt motor with a 240 volt, I cannot see any reason why not, as long as the new motor fits.

Will the pressure switch on your compressor toggle 240 volts rather than 120 volts? I would expect so, as it is just a relay. You need to watch that to make sure.

If you are trying to convert a 120 volt motor to a 240 volt, than can only be done if the motor is pre-wired to accept that conversion, and I do not know if that is the case for your compressor motor.

As to what motor you should use, I would remove the existing motor and take it with me to an electric motor shop, and ask them to provide you the same, in 240 volts, or, to check that motor to see if it can be converted.

Cheers,

Bill

Wiring in a 6- gal 240 volt compressor

I am having trouble figuring out how to connect the 320 volt cable to the compressor switch. Two connections are labeled line so I assume that I connect the two hot wires there and connect the ground wire to the green screw on the frame. The line connections are weird. Do the hot wires go into the front and do I need to get some connector to go on to the hot wires so they will go into the switch? Help

I'm happy to post this for you in the hope an electrician will post a response. I am not qualified to provide electrical advice.
