While most homeowners know that there are both two- and three-prong outlets available, you may not realize the differences to these features unless you’re a licensed electrician. However there are some crucial differences between them. Find out which option is best for your home with the following guide.

Two-Prong

Two-prong outlets are commonly seen in older homes and any construction built before 1960. These outlets feature a hot wire and a neutral wire, but lack a connection to the ground wire. The hot wire provides electricity while the neutral wire transports electricity back to the main panel. 

Although these outlets may support your two-prong electronics, most electronics with a metal case feature three-prong plugs, and thus require three-prong outlets. This is because these devices are more likely to cause electric shock without the proper grounding. 

Three-Prong

Like two-prong plugs, three-prong plugs also feature a hot wire and a neutral wire. However, the third hole adds a ground(ing) wire. This ground wire sends any excess electricity into the ground, minimizing the risk of electrical shock should a surge occur. They can also help you avoid electrical fires and damaged electronics. For these reasons, licensed electricians always recommend three-prong outlets over two-prong.

Why Install Three-Prong Outlets

If you have an older home, upgrading to three-prong outlets is an important safety measure. A licensed electrician can install ground wires and then provide you with three-pronged outlets to help keep your home safe. 

You’ll likely need to perform the upgrade at some point, as many devices require three-prong outlets, and two-prong outlets may not pass home inspections.
