I have dug an irrigation well (40 feet), and installed this pump: http://www.amazon.com/gp/product/B005X53JC8

It has the following description: Red Lion RJS-75-PREM Shallow Well Jet Pump, Cast Iron, 1-HP 24-GPM

The pump did not come with a power cord, and therefore I'll need to wire up a cord and plug to the pressure switch.

What gauge wire does this pump take?

I current have wired up a computer cable, I'm guessing the individual strands in there are maybe 16 or 18 gauge (no idea, really). I noticed that the chord gets pretty warm when the pump is running.

Should I go with a lower/thicker gauge?

Thank you in advance!

  • It would help to know where you are. The pump appears to prefer 220v, and another commenter mentioned that it requires at least a 15 amp circuit, which implies at least 14 gauge and possibly lower, depending on distance, . – gbronner Aug 15 '15 at 19:10

    You have a 1hp pump wired to a computer power cord??? Are you aware that that is nearly 18 amps @ 120V?? – Speedy Petey Aug 15 '15 at 19:39

    The I would recommend 30a circuit using #10cu and hard wired. IMO your best and most efficient bet would be to run it at 240v and then plug it in. This way you can use easier #12 wire and the plug/receptacle will serve as your required means of disconnect. – Speedy Petey Aug 15 '15 at 21:52

    To run it at 120v yes. Don't forget everything on the circuit would need to be rated 30a, the breaker can be 25 or 30a. – Speedy Petey Aug 15 '15 at 22:01

    @SpeedyPetey -- make that an answer and I'll upvote it :) – ThreePhaseEel Aug 15 '15 at 23:55

To run it at 120v you'll need to have a 25 or 30A breaker and #10cu wire. Typical would be 10/2 cable.
