3 Prong to 4 Prong....

[dave carver]

I just got an old dryer from the Mother-in-law. It has a 4 wire plug. Outlet is 3 wire. We got the new 3 wire plug....now...how do we wire it in?

4 weird is 3 phase, which is weird for residential... but not compatible with single phase.

4 wires is normal. 2 hot, neutral, ground. 3 wire outlets share neutral and ground. You can remove a cover where the cord goes in and swap the cord out. There's probably a diagram under the cover.

The 4 prong, in this case, is not 3 phase. It's a NEMA 14-50P.

There are you tube videos that show how to do this...
