wiring problem

I had an electrical outlet put outside my house by an electrician who wired my new house. Come spring I ran a wire to my work shop from half of the 220 box, but I only need 110 for my tools. How do I correctly run 110 from 220 without alot of rewiring. Oh buy the way the electrician since has quit the business.

Are you saying that the outside receptacle is a 240 volt receptacle, and that you want to run 120 from it?

And what do you mean by "half of the 220 box"?

electrical sense

hi, you hopefully know that one side of electrical panel or BUS has a voltage rating up to 125 volts potentially. therefore all you need is a 20 amp circuit leading to this location i assume. you will need #12 awg wire uf grade to feed it underground thus what uf stands for underground feeder, or you can use 1/2 inch pvc schedule 40 or 80 conduit, run this underground i think codes call for depths of 18 inches. you will want to run #12 awg thhn stranded wire to this outlet. theres more details, to this application than i mentioned. basically though if you have a white nuetral wire, any colored wire other than green or white for your hot or voltage carrying wire and a bare copper wire for your ground you will have a complete circuit. hope you find this helpful, goodluck and be safe! the library has very helpful basic wiring books that can really be helpful also.

The answer is you don't. Change the circuit over to 120 volts (at the panel) and then extend it to the shop. Or run a brand new circuit to the shop.
