four prong dryer cord
Almost all manufacturers sell dryers without a cord attached, allowing you to select 3-prong vs. 4-prong dryer cord to match your outlet. Be sure to check which type you will need before purchasing your appliance and power cord.
Can I use a 4-prong dryer cord?
Since the code change, new dryer outlets must be wired with separate neutral and ground wires. These outlets have four slots and will accept only 4-prong electrical cords. Homeowners owning older dryers with 3-prong cords are sometimes perplexed when they move into a home that has a newer 4-slot outlet.
Why does my dryer cord have 4 wires?
However, in new construction the installation of kitchen ranges and clothes dryers requires a 4-wire cord and plug. The 4th wire in that cord and plug configuration is an equipment grounding conductor. This equipment grounding conductor is the missing wire in the older 3-wire configurations.
What is the difference between a 3 wire and 4-wire dryer cord?
3-Prong vs 4-Prong Dryer Hookups: What’s the Difference? The key difference between a 3-prong and 4-prong dryer hookup is the wiring. The 3-prong dryer hookup has only two hot wires and a neutral wire. On the other hand, the more modern 4-prong dryer hookup has two hot wires, a ground wire, and neutral wire.
Can I change my dryer cord from 3 to 4-prong?
Answer: You don’t. It is not possible to install a four prong outlet using only three wires either legally or safely. Put the three prong outlet back and install a new three-prong cord on the dryer.
Why do new dryers have 4 prongs?
Today all newly installed outlets for dryers must be compatible with a 4-prong outlet. These updated outlets contain a separate ground that eliminates the possibility of a current traveling back to the machine. This also helps to avoid electrical shock or even fire.
Can I use a 50 amp cord for a 30 amp dryer?
You should not use a device that requires 50 amperes on a circuit protected by a 30 ampere breaker. If you or the installers installed the wrong cord on the dryer, simply replace it with the proper cord.

Why do some 220 plugs have 4 wires?
The reason this change was mandated by the National Electrical Code is that the 4-wire setup is inherently safer and better able to prevent electrical shock, which in the case of a 220/240-volt circuit can be fatal.
When did dryers go to 4 prong?
It wasn’t until 1996 when the National Electrical Code (NEC) was updated to require 4-prong dryer outlets in all new homes.
How do I know if I need 3 prong or 4-prong?
It’s really a very simple fix. In residences built before 1996, the National Electric Code (NEC) required only a 3-prong outlet for electric dryers and ranges. As safety requirements became more stringent, the NEC began requiring a 4-prong outlet for new installations of circuits that provide power to these appliances.
