Does the square D pressure switch work in 110 for a water pump for the house?

most switches work both 110 or 220 volts, this pressure switch should have a diagran on the inside of the cover, if you are still not sure go back to the place that you bought it at, and ask, home depot, lowes, should know and tell you how to wire it so it will work.

Its a water pump for our house and barn pumps probably close to 300 to 400 gallons a day over the course of the day was wondering if it is wired for 220 if using it with 110 will ruin it

Unless the pump motor has provision on it specifically for running on 110, then yes, running a 220 motor on 110 will ruin it. It will cause the motor to overheat, if you can get it to work at all. Some 220 motors are designed so that you can run them on 110. If yours is, it should have instructions and a wiring diagram for that. Even if it IS designed for 110 or 220, running it on 110 WILL cause it to run hotter, and will shorten its life.

My pump (pentair whisper flow 1 hp) has been making noise for about a year. Then it started making a clicking noise on top of that, and I knew it wouldnt last but a week. A day later it never came back...

Based on your description of the breakers you should have 230VAC to the pump motor. Even if it is only 115VAC you should still get a response from the unit when powered on. A 230-connected motor will run on 115 for some time but will overheat and eventually fail. If you are getting nothing you have issues with the power as well as the pump. Get the $40-$50 multimeter and check your line voltages to ground and line-to-line. You will find a problem somewhere.

And to answer your other question...yes, connecting 230VAC to a motor setup for 115 will burn up the winding.

The hot water heater should come with an amperage rating on it.
They vary from 30 to 40 amps, and then 10 or 8 gauge wire.
(All hot water heaters are 220 volt.)
I believe the 602 uses a 4500 watt element.
Divide 4500 by 220, and you get about 20 amps.

If you want to be on the safe side, you go with the heavier wire, 8 gauge, and then go with the smaller breaker that is more easily tripped, 30 amps. That way you can switch to a 40 amp breaker in the future, without having to change the wiring. The goal is to always make sure the wire is rated higher than the breaker. You want you breaker to trip before your wire melts.
But technically a 30 amp breaker and 10 gauge wire would be fine for this heater.

And since it is 220 volt, you will always use a double breaker.
That is because 220 volt appliances don't use a ground, but instead use the potential between to power wires that are 180 degrees out of phase. AC always does a sine wave, and the 2 power leads coming into the house are always out of phase. When one is 110 volts up, the other is down. So the total between them is 220 volts. And the way they intentionally zigzag the breaker box, 2 breakers next to each other always are on opposite power lines.

If you have any doubts at all about 220 and water heater wiring, please ask again. Wiring is not hard, but you have to understand what you are doing, or else you can cause serious consequences.
For example, if you use wire nuts or wrap wire around a screw, you need to always turn them clockwise, so they pull the wire when tightened.
You also always need to ground the chassis with a green safety wire.
Since a 220 hot water heater uses 2 power wires and a safety ground, the white wire should be striped with a permanent marker, so that it is not confused with the white neutral wire of a 110 volt appliance.

Need wiring diagram for 1081 motor,1.5hp.I want to change from 220 to 110.

What is the reason you want to change? 220 is not only stronger ... it is cheaper to run. If wiring is a problem, (this pump should be on its own circuit) simply replace the single pole breaker with a double pole and take the existing white wire and turn it into a "red" wire for your 220, (put the white (red) wire on the second pole of the new breaker.)

If you will remove the cover on the back of the motor, you will probably find a plug that you move from the 220 position to the 110 position. Change the plug from 220 / 20 amp to 110 / 20 (or what ever the motor will require) Normally, when you change the voltage in this direction (down) you send the amps up by 2 times. What I mean is if the motor uses 7.5 amps at 220, you will be using 15 amps at 110. Make sure you have at least #12 wire for a little extra safety.

Thanks for your interest in

If you are replacing a 2 hp pump with a Hayward 2 hp super pump on a 220 line is L1 white and L2 black

Shouldn't be a white line on a 220 circuit but some people use them. Red and Black is the standard. If you are sure they supply 220 VAC, which I would verify, it doesn't matter which one goes to which terminal. 120 or 3 phase matters. If you have a multi meter, put the red lead on the black wire and the black lead on the white wire. If you read 220, good. If you read 120, it will make a difference.

Jun 26, 2010 | Hayward SUPERPUMP 2.0 HP, 115/230V

1 Answer

I have a brand new 1hp water ace water pump 230/115 switched to 115. The motor hums for 30sec then stops, but the pump does not turn. Then it will hum again in about 4min. I shut it off after that.

If it was initally wired for 230, I question who rewired it for 115, the reason is 230 is a foreign relation in the metric world, 220 in our world, in which case two of the wires wires hooked up according to non American standards. The scamatic showed the change over inside the cap, but in china the white is the ground and the green is reversed with the red to make the motor in reverse, confused, you should be, cause I'm not looking at the motor so there is no way for me to know what you have there! What I'm saying is stop before you burn up the motor and take it to a motor shop that knows about the proper rewiring to change it from 220 to 110. 4 Min. is a long time, you may have already fried it. Good Luck!
