Extending a 220 line

[MarkStanford]

Hi all. I am in the middle of a remodel and we moved the dryer into our garage. I want to hook the dryer back up but the old line is in the attic and won't reach the garage. I have an old 220v line that I used to do some welding with. Can I splice that onto the old dryer line to extend it? I've never spliced a 220 so I don't really know what I'm doing here and I don't want to burn the house down.

Thanks in advance!!

As long as you use an accessible junction box and the right size wire it's not a problem.

Make sure your extension and the line you used to weld with are the appropriate size of wire for the current. Sometimes using smaller wires is permissible for welders (based on duty cycle etc) but it wouldn't be for a dryer.

The new receptacle will have to be 4-wire, 3-wire is only allowed in existing installations and if the wiring that the OP wishes to extend does not support a code required 4-wire device it will need to be replaced all the way back to the panel. Dryers are 120/240 volts & it used to be allowed to ground the frame of the dryer to the neutral.

Nice. Thanks guys. How would you splice it? Would you splice and cap like a typical 110 in a junction or should I splice and electrical tape it? Or is electrical tape a bad idea?

Thanks again. What a great forum. Can't believe I am just discovering this....

110 & 220 are pre WWII voltages in North America, current standard is 120V & 240V.

A Ideal® Wingnut® or a 3M® wire connector are good choices, no tape required.

Junction box and wire nuts, do it all the time because when they build houses around here the electrical contractors seem to think Romex doubles as guitar strings and should be pulled tight to at least low E.

Haha. That's what I was originally thinking - "let's pull these as tight as humanly possible and double bag them with electrical tape". Sounds like overkill.

Thanks guys. Huge help.

As was said, the new feed should be 4 wire, run a new cable.
