Question – Why There are Different Types of Dryer Plugs
The new electrical code calls for a 4-wire plug for dryers.
When talking about electrical wires and outlets for dryers, are there 2-prongs and a ground prong, and are there 3-and 4-prongs with a ground? Why did we get a choice of plug type at Sears?
Fact is that the new electrical code calls for a 4-wire plug which has 2-Hots, 1-Neutral and 1-Ground wire – this code is for new homes and remodeled projects.
The 3-wire plug has 2-Hots and 1-Ground wires – this configuration bonds the Neutral and Ground wires together inside the dryer at the cord connection area.
Both configurations work fine, it’s just that they need to accommodate your particular plug style at your home.
