Upgrading your electric range, dryer, or stove requires the right wiring. Most new appliances come with a 4-prong plug, but older homes may only have a 3-prong outlet. Fortunately, it is possible to convert older outlets to accommodate newer appliances. In this article, we will discuss the 3-prong to 4-prong wiring diagram in easy-to-understand terms.
Understanding the Difference Between 3-Prong and 4-Prong Outlets
Before we delve into the wiring diagram, let’s first understand the difference between a 3-prong and 4-prong outlet. The main difference is the number of prongs on the plug. A 3-prong plug has two hot wires and a neutral wire, while a 4-prong plug has two hot wires, a neutral wire, and a ground wire. The ground wire provides extra safety by preventing electrical shocks and fires.
Most new appliances come with 4-prong plugs because they are safer and more efficient. However, older homes may only have 3-prong outlets. If you want to upgrade your appliances, you will need to convert the outlet to a 4-prong outlet. This can be done by following the 3-prong to 4-prong wiring diagram.
