That's because until recently, homes were wired with two different receptacle styles: 3-prong and 4-prong. Knowing that homes had a variety of outlet types, it didn't make sense for appliance manufactures to pre-wire the stove with one or the other. The 4-prong plug adds a safety ground wire in addition to the two hots and neutral found on the 3-prong plug. Below are pictures of both a 3-prong and 4-prong style outlets with respective labeling. With a voltmeter you can check for proper voltage on the wall outlet before plugging in your appliance. You should measure VAC between lines hots , and half of that voltage if you measure between either of the hots to neutral. If you are wondering how to wire a dryer with a 4 prong plug but you have a 3 prong wall receptacle you have a couple of options.

Before , it was standard practice for volt clothes dryers to have three-prong cords that plugged into volt outlets. In this configuration, the ground connection on the dryer was bonded to the neutral connection, so that the single wire served both functions—as the neutral current pathway and as the grounding pathway. This didn't mean that the appliance wasn't grounded, but that the neutral wire also served as the grounding pathway. This is normally not a problem, since neutral wires are always grounded in the main service panel. Under some unique circumstances, though, there is a very small chance of shock with this configuration. Since , the NEC and standard local code practice have mandated that new installations must include four-slot dryer outlets for volt dryers and that dryers must be fitted with four-prong cords to match them.
