Wiring Connections For A 3 Prong Dryer Cord
Electrical Question: I have an electric dryer with a 3 prong cord but my wall outlet is a 4 prong.
- I bought a 4 prong cord to switch out but before I installed it on dryer I wanted to make sure plug would fit. (I who knows nothing about electrical wiring or dangers).
- The cord was on the ground with all 4 wires exposed when I plugged it into the outlet. Of course it arced and fried the ring terminals.
- I turned off the circuit breaker to unplug the cord. I realize I could have fried myself now but my question is now that the new 4 prong cord has been installed on dryer and we plug it in, it does not work. Did I fry the plug?
Background: Toni, a Other from Santa Cruz, CA.
Additional Comments: Your website was helpful in showing me how to switch out a 3 prong to a 4 prong dryer cord.
Thanks for your electric wiring question Toni.

How to Connect Your 3Wire and 4Wire Dryer Cord
- Always make sure the dryer cord is not plugged into the receptacle when making the wiring connections.
- NOTE: As with this question, shorted wires typically do not damaged the 220 volt receptacle outlet.
- If the dryer circuit breaker trips off, make sure to fully reset the circuit breaker, all the way off, then back on after the wiring and connections are completed.
- If a 240 volt dryer circuit should trip off It is very possible that just one side of the breaker has tripped, or half of the circuit breaker. In this case the circuit breaker should be turned all the way off before making any wiring connections.
- For best results, the ring terminal connectors should not be damaged, however if they are damaged they may be cut off and replaced with new ring terminal connectors which may be obtained from your local hardware store.
