Re: New Shed Wiring

I'm sorry I've been away from this so long. I looked in the breaker box on
the service pole and what I saw really scared me. Needless to say, I will be
digging and laying new wire in PVC out to the new shed. The distance is only
ablut 30 feet (probably less). I've tried to downlod pictures of the breaker
box and wire, haven't had too much sucess. I do have picts of my deck,
bathroom remodel, the old well topper and such in the photo album. Not sure
how to post a link. Anyway guys, I really appreciate all the advice and as i
get closer to running new wire, I will be back to ask more questions.

Thanks all
Kaye

How can I best accomplish this without burying more wire.

He did know what he was doing. You just failed to specify that you
wanted additional capacity for expansion. Before you start messing
around with trying to get different voltages and a nuetral out of your
current set up, how much total power can you pull over the existing
wire? Even if you had four wires, the hot leads are probably sized
for the pump, which would leave you no excess capacity anyway.

You should break out the old shovel, and put in a new feeder line
to a sub-panel in the shed, and re-route the feed to the well
pump through that.

Failing that, mount some solar panels on the shed, and or
feed a UPS through a transformer.

Note that many wells can't deliver water fast enough
for fire-fighting purposes anyway.
Systems that deliver 7GMP at a mere 40 PSI with 50Gallon
pressure tanks aren't uncommon.

You really need a cistern
with at least 500 gallon capacity, and a pump that can
deliver 30 GPM at at least 75 PSI.

A better system would be 3-5,000 gallon reservoir,
and 50GPM at 100+ PSI.
