Hi Dean,
You should be able to tell what amperage you need by just looking at
the circut breakers that are presently supporting your well pump ... I have
a 5000 watt Honda Generator that I use for camping and possible power
outage.What do you consider a LARGE generator? The one I have I can carry by
myself...it's heavy...but managable.
I also am on a well system and my pump is 220 volts, on a pair
of breakers that read 15 amps.
I bought an emergency transfer switch for any long power outages. It
will give me six 110 volt circuts or can be wired to give one 220 volt
circut with four 110 volt circuts...I bought the one seen he

It works great and am actually disapointed that I haven't been able to
use it yet...powers always on....!...Jim

I'm looking for a way to run the deep well pump, I don't know how much
HP is it, but I think its on a 40 amp circuit at 220V. I've looked for
a 220V inverter, but I can't find anything online.

Is there ANY other way to start a well pump, without buying a large
generator?
