If you live in a home that was built prior to 1996, the outlet for your kitchen range may still require a 3-prong cord. It is, in fact, considered code-compliant to continue using the 3-prong configuration in pre-1996 homes. Why is this date important? The National Electric Code (NEC) updated their requirements for 240-volt appliances and changed them from 3-wire cords and receptacles to 4-wire cords and receptacles.
The code applies only to homes built after 1996; however, you may have run into an instance where you were faced with trying to hook a 4-prong range cord up to the home’s 3-prong receptacle or vice versa. The difference is that in older appliance installations, the legally-installed 3-wire cord consisted of wiring that was configured with two hot wires and one neutral wire. The new 4-prong construction provides the 4th grounding conductor that was missing in the 3-wire configuration.
The problem with this configuration was that the appliance may not always trip the circuit breaker. An example is if the 3-prong’s neutral wire wasn’t connected to the metal frame and housing of the appliance. If there is no return path for the current to flow back to the source, then the metal housing is energized, and it can deliver a shock to a person who touches it.
By the laws of physics, the moving current of the neutral wire will naturally follow the path of least resistance. Electrical current on the exposed metal could easily make contact with a human being in order to continue its path, which is why the NEC changed the requirements for ground connections on 240-volt appliances.
New ranges are sold without the cord so that you can install the cord that fits the outlet in your wall. If you live in an older home that has a 3-prong outlet, the NEC code allows you to change the cord to match the existing outlet. Conversely, if you move an older appliance that’s outfitted with a 3-prong cord into a newer home, you can also change that cord to one with a 4-prong configuration to match the new outlet.
