The 240 line that was installed for my oven is just about 3 inches to short to allow the plug to rest in the recessed area of the range. Therefore, the range sits about 1 1/2 inches from the wall and it's driving me crazy. Can additional wire be spliced to the end of the existing in order to extend it just a few more inches?

Are you talking about the cord from your range that plugs into the wall? You could get a longer cord... even make up your own. Just make sure the size and length of the cord matches the power requirements of your range. Let us know the amp requirements of your range and the length of cord required. The guys here can make a proper recommendation of the size wire (cord) you will need. I most definitely wouldn't splice the existing cord.

If you're talking about the wiring in the house, the only way it can be spliced is in a junction box.

You can extend your 240v line--using your existing electrical box as a junction.

Is the wire install copper--with four conductors?
Also note that when you extend your wire from your junction box to a newly installed electrical range box, it would be best to make sure the new box is securely mounted--seeing that you are not dealing with a typical light-weight 14AWG.

While I agree with the above answers, I think more needs to be said. I do hope if it is a new run of wire, it is XX-3 with ground. If you extend the wire with NM-B, it should stay behind the drywall. You can cut a hole for the new box and work through it to fish the new wire through. Once out the hole, you can secure it to an old work box and pop the box into the hole. You may even luck in and be able to keep everything inside the same wall cavity. The old box with the splice must have a cover and remain accessible.

If you have an unfinished basement or craw space, you may have enough slack in the wire to move it. You could be lucky enough the wire is too long, and can easily relocate the receptacle.

I do hope if it is a new run of wire, it is XX-3 with ground.
