220V electricity and 110V

[Looking4new]

I don't know if this is do-able or not, but I want to take 110V hydro off one of the 220V legs of the power that is going to my well pump. The pump is 220V and draws 5amps. There are 27.5 amps available in the 220 circuit. The way I understand it is that the 27.5-5 amps leaves 22.5amps I want to use 1 leg of the 220 circuit so that would be 11.25 amps -2% would be 11.025 rounded down to 11 amps of 110V juice. This juice would be for my water softener and a led light over top of the whole issue. Is this even do-able? I don't want to toast my house.

That is no problem if the water softener draws less than 22A. If it does draw that much that would not be ideal tho because the leg its on would be fully loaded -- 5 + 22 =27 -- and may pop the breaker during the brief demand surge when the pump starts. Are there 3 wires or 4 wires in the line youre tapping off of? ... I kinda wonder at a ?27.5A? breaker on a pump that only draws 5A. More than enuf. :confused3:

A water softener sure wouldn't draw enough amps to interfere with your plans I wouldn't hesitate.

I'm no electrician but you might be able to just add a subpanel that is fed by your 27.5 amp circuit which would allow you the flexibility to add a breaker sized for your pump as well as additional breakers for the light and water softener. Make sure you use the right sized wire and breakers and keep the grounds and neutrals separated.

The lamp draws 4 amps, the water softener draws 2.1 amps. From the 220V line there are wires as follows. 1 red, 1 black (these are both hot, 1 green (ground) 1 white (which in my meager understanding is common in 110V circuits. Do I need it in 220V?

Are you out of breaker panel space? Or is your water softener along the way to your well? Where is your pressure switch? Well circuit only hot while pumping - down stree from pres sure switch. A simple safe and code would be to use a 220/110 transformer. Your loads are ready low so it wouldn't be very big or expensive

Is your start capacitor inside your house or in the well?

you do not need white in 220 volt circuts

What kind of LED lamp draws 4 amps - 480 watts at 120 v? Really a lot of light!

The pressure switch is in the water line beside the pressure tank in the house. The pump is down hole in the drilled well.
The water softener is down stream from the tank and pressure switch.....The water softener has its' own transformer that plugs into 110V (24V 2.1A)
