AboutJeremy Adams Expertise I can answer basically any question pertaining to the field of electricity, its applications and daily uses, theory, calculations, how to for residential, commercial, and light industrial. I am an inside wireman, therefore I can't help much with questions to do with linework, such as powerlines and distribution switchyards. I can however, answer some questions that have to do with power generation.
Experience I have 15 years in the trade and currently I am employed at TVA Cumberland City Fossil Plant where we generate about 10% of the power used in the Southeast. Of those 15 years, I have wired houses, wired many office complexes, banks, hospitals, schools, industrial applications, and can also install fire alarm systems.

Question i am trying to add 2 110v outlets from my 220v outlet that already is available. i want to keep the 220v outlet and add the 2 110v outlets. i have 10-3 with ground wire. wires are black - red - whit- and bare copper. can u tell me how to do this? thanks
Answer Phil,
This is pretty simple. What you have for 220v is two hot wires, a neutral wire and a ground wire. Now for 110v you will only need one hot wire, one neutral wire and your ground wire. Black and red are primary colors used for hots. White should always be neutral. Green or bare signifies your ground. Now on your receptacles you will notice one side is a brassy colored screw and the other side is silver, just below the silver screws you should have a green screw. The brass screw is hot, silver is neutral and green is ground. Use the colors I listed above to connect the new receptacles. If you're using 10-3 w/g to connect the 110v receptacle then you will have an extra wire. Just be sure to cap it off on both ends.
Now in order to balance the load of your circuit I would do the following: For 110v receptacle #1 use the black wire for your hot off the 220v receptacle. For 110v receptacle #2 use the red wire for your hot off the 220v receptacle. I hope I haven't made this too confusing for you. I just want you to fully understand what you are doing. Let me know if you need more help. Be sure to turn off the circuit breaker before you get started.
