2 Prong Electric Outlets

Are there two-prong outlets in the home? You may need to take additional precautions to make sure they are safe to use. Two-prong outlets were once the norm in older homes but they are no longer safe and effective.


Let’s first take a look at the prongs on electrical tools, extension cords, and other devices before you remove them from your 2 prong outlets. Let’s find out why they exist and how we can upgrade them to code 3 prong outlets.

Are Two Prong Outlets Dangerous?

Two-prong outlets are dangerous and outdated because they lack grounding. Grounding is the way electricity is safely transferred when there is an unstable current. A short circuit is an electrical event that causes dangerous current to travel through ground wires. This allows the current to safely transfer and not shock you or your plugged-in appliance.


This is why two-prong outlets are the most dangerous type of outlet.

Two-Prong Outlets Upgraded to GFCI

Ground fault circuit interrupter or GFCI outlets are designed for protection against electric shock. This is the only three-prong outlet that can be used to replace two-prong outlets without violating NEC code guidelines. Even without the grounding component, GFCI outlets still provide protection against electric shock. If you replace a 2-prong outlet with the GFCI outlet, it must be marked with a “No Equipment Ground” sticker.

Are two prong outlets safe to use?

There is nothing wrong with using the two prong outlets. They aren’t dangerous. But, you should not plug a three-prong plug into a two-prong outlet. Refrain from using the adapter that converts two-prong outlets to three-prong outlets to plug in power cords or overload the circuit.


What is the cost of changing 2 prong outlets into 3-prong outlets?

If no walls are required to be opened, expect to pay $25-30 per linear foot for running new wire. All things considered, the cost of upgrading to a 3-prong outlet ranges from $100 to $300.


How can you make a 2-prong outlet more secure?

Install a ground fault circuit interrupter (GFCI) receptacle to increase the safety of your existing two-prong outlets. Even if the GFCI is not connected to a ground, it will protect you from a fatal shock.
