Is my Well pressure switch wired right?

[JOE.G]

Hi, Today I decided to clean out the tube that the Well pressure switch is connected to ( Completely clogged not sure how it was working ) and I cleaned up the switch.
I have a Sta - Rite SK 2 switch which I adjusted to be a 40/60. I also have a 1/2 HP 230 Volt well pump.

Now I have had no problems but my wiring does not seem to be like anything I have seen on the net.

The first pic is of my cover
2nd is my switch
3 and 4 are samples off the Net.
Mine is wired 2 out side posts to a 2 pole 20 amp breaker and the middle wires go to my Pump.
I did attach wires better when I put it back together.

That would be correct.

Your white wires are hots, so you should color the white near the end of the insulation. You can use a Sharpie marker.

Okay so mine is right? I could switch the two power wires ( White and black from breaker box ) with each other and also switch the two motor wires ( White and Black center wires ) with each other and it would be fine?

Why do the pictures I took from the net have black with black and white with white? It appears they dont have the motor hooked to both center screws which the label says they are for the motor.

I am trying to learn and I thank you guys for the help

Correct = right.

Yes, but you could also just do one or the other. Maybe put both blacks on the left, or the right. Then you would have black with black and white with white. It would work the same, but look better. One advantage to that is there is no way to mess things up that way, where we really could not tell, without your words, that you did not do it wrong.

It appears they dont have the motor hooked to both center screws which the label says they are for the motor.

Electrically, you could change 1 with 2 or 3 with 4 and it would work. But it seems that it is a convention to put the wires from the breaker on the outside.
So how about you switch 2 with 3, and everybody is happy.

Thank you guys for the replies, Reach you are saying I could put the motor leads on the outside terminals and the power leads on the inside and it would still work? Not that I am going to just trying to learn. Thanks

Yep. Makes no difference.

What are the difference between these Square D Switches, One is a 40/60 the other 2 are 30/50 I think one of them has adjustable pressure spreads and the others are fixed? Does it matter which I get as they are adjustable between 30/50 and 40/60?

Am I better off getting one with out low pressure cut off?

Am I better off getting one with out low pressure cut off?

Often. Will your well potential run dry?

The deal is that this is not a sure-fire cutoff when the well runs dry, because your pump might be pumping a mix of air and water for a long time. There are electronic devices that are much more sure. But the low pressure cutoff switch is cheap.

I did not look at your links.

I find the low cutoff to be just a nuisance and so I lobotomized it.
You can search for those part numbers on https://www.se.com to get the data on each model for comparison.

The well could run dry while the tank is refilling and the water is no longer used. If it is a jet pump, then most likely there is a loss of prime already so it is not likely to recover without human intervention. The pressure will not drop to the cutoff if there is no water used until after the pump heats up and melts the plastic pipe or the seal in it blows.

If ever you can draw the water faster than the pump can supply it, it will nuisance trip. Same thing if there is a power failure and water is used. Every time it happened to me, I was not at home and I would have to explain to the wife how to hold that lever "just so" to get the pump to run and keep holding it "just so" until the pressure returned above the cutoff.

 

[JOE.G]

I am not sure if I would draw the pressure down lower then the pump can supply, What pressure does it trip it at?

 

[LLigetfa]

There is no set pressure. It follows below the cut-in setting.
