Supreme 4 Wire Plug To 3 Wire Dryer
If you are faced with the problem of a dryer plug and dryer outlet that don t match there are two possible remedies.
4 wire plug to 3 wire dryer. One is to replace the old circuit by installing new four wire cable and a four slot outlet each with a dedicated ground. This is a job for an electrician and it brings the circuit up to code. This is an allowable remedy under the electrical code which grandfathers in older installations.
Three prong cords and 3 slot outlets were once the norm but since 2008 article 550 16 a 2 of the national electrical code nec has stipulated that connections for electric clothes dryers must be made with a 4 conductor cord and 3 pole 4 wire grounding type plugs or by type ac cable. It s much easier and much less expensive to replace the 4 wire whip with a 3 wire whip. The older 3p 3 wire dryer circuits are still legal and safe to use so there s no need to rewire your dryer branch circuit to install a new dryer that came equipped with a 4 wire appliance whip wire.
