lawn pump

20 amp Breakers at the Box pump is reading 115 at the lawn pump took the switch off because I'm not sure if the switch was wired correctly and wire directly to the pressure switch but pump won't come up to speed its running real low wondering if I have burned the pump up running it on 110 or if that's supposed to be 2:20

Welcome to the forums.

You need to look at the pump and see what voltage is listed on it.

Just to add further information.... if there are two breakers or a large breaker with two combined handles then the pump should be wired for 240v.

You need to check across the two breakers for 240vac.
From each breaker to ground you'd measure 120vac.

What do you mean by "quit working again"? Was the former pump operating OK and then failed? If it was replaced with a pump with the same specifications and wired the same, the breaker is not the issue. If the motor is designed for 120/240, you must connect it for the voltage available at the panel breaker. Good luck.

I believe this post is a response to original post from yesterday and should be moved there.

To goodwoodbenice:
Having trouble understanding your response due to lack of punctuation. Also as I asked in my first response, what happened with the pump to be in the present situation?
