Can you explain three prong and four prong cord conversion?

I need to understand 3 and 4 prong conversion.


Answer by  lwetzel2003 (37)

A four prong plug can be changed to to a three prong cord by connecting the ground and neutral wires together on the applince. You can also use a 4 prong cord on an older 3 prong appliance by connecting the ground and neutral of the cord onto the same terminal.

4 prong contains not only a ground and two load wires (power wires) but also a neutral wire. Some devices need a neutral wire to because one aspect of the device require 110 voltage. So you need to know where the neutral would hook up or if it's needed.

I moved new dryer (4-prong plug) to an old house with a 3-prong receptacle. There is "adapter" or must I re-wire either the dryer plug or house.
