Tommy cowett show how to connect a newer dryer with a four prong electric chord to his older 3 prong outlet.
Change from 3 prong to 4 prong dryer. The key difference in the wiring configuration between 3 prong and 4 prong cords is that with the older setup the 3 prong cord has only two hot wires and one neutral wire there is no separate ground wire. Before the mid 1990s most electric clothes dryers operated with three prong plugs that fit into three slot outlets but since 1996 the electric code has required four slot outlets.

When moving a newer electric dryer into an older house it s not uncommon to find that the cord and plug included with the new dryer doesn t fit the 240 volt dryer outlet. If you want to replace your three prong dryer outlet with a four prong one you have to run a ground wire back to the panel and connect it to the panel s ground bus. An alternative would be to ground the outlet separately to a metal stake driven into the ground or possibly to a suitable metal water pipe.
