We have replaced our electric stove with a gas stove, and now we have a 220v outlet that I have taken apart to make space for the range.

The 220 is wired to the main box on a 50 amp breaker. I am working on finishing our basement and wanted to use this circuit for the basement power requirements. 50 amps should be more than enough power, as I'm only setting up 2 computers, an LCD TV with DVD, two pieces of exercise equipment, and two track lighting fixtures. I did the math but don't have the numbers in front of me... I'm good though.

The question is... The existing 220v cable run goes right to the back of the range which is on my main floor. I need to get the wire into the basement so I can connect it to another box and split it off... 2, 15's and a single 20 amp breaker...

Whoever built this house made sure that any cable runs would be a huge pain in the you know what, as the main box is located in the attached garage, on the outside wall. Is there a way to simply extend the existing 220 run, just long enough to get me into the basement so I can wire from there, or should I just run a whole new wire?

Any suggestions would be appreciated! Thanks!

First off, what kind of cable is this, specifically?

Can I assume you want to use it to feed a sub-panel?

The cable has 3 wires... 2 of them wrapped in black, one of them is just a bare wire which I'm assuming is the ground.

And yes, exactly. Want to use the cable to feed a sub-panel box, and from there install 2, 15 amp, and 1, 20 amp breaker. Thanks!

Well this cable is not really good to use for a sub-panel. You CANNOT get 120/240v from that cable. Just 240v or 120v.
