110 from 220


Hi, I'm trying to add a 110V receptacle to an outside wall in order to power a soft water unit. The only electrical that's close to my softener is a 220V pump that is switched. There are 2 110V hot wires connected to the switch which is then connected to the pump through the switch but there is no neutral. Is there a way that I can make a 110V receptacle by pulling power from the one of the hot wires of the switch if there is no neutral? If so, how would I configure the wiring? I assume, if there was a neutral, I would simply take one of the hots and the neutral to create a 110V receptacle. Thanks in advance.

I am not an electrician, you will have to wait for one to answer most of your questions but, running a 110 line from one leg of the 220 breaker is not a good idea, if that 110 shorts out, it will not kick the 220 breaker. I may be wrong so a real electrician will have to answer this also.

Even if you had a neutral there is no safe legal way to do what you want to do.

No. You will need to pull power elsewhere.

Re: 110 from 220


Thanks to all of you. I will take your advice and pull a new line from the main panel.

Also, shouldn't there be a neutral for the 220 pump and switch? It was done many years ago by who knows who..

Unless the 240 volt application has a need, such as a timer, clock, or other lower voltage application built in, the 240 volt set up needs no neutral.

Another option is to get a transformer fed from the 240 volts.
