Supplanting a 3-Prong Electric Dryer Cord With a 4-Prong Cord
Making Your Dryer Work With a 4-Prong Cord
Because of changes in the National Electrical Code (NEC), wiring for electric garments dryers changed in 1996. Prior to the change, dryers utilized 3-prong strings that connected to 3-space electrical outlets (repositories). This design did exclude a devoted ground association; the dryer’s gear ground (case ground) was associated with the nonpartisan conductor in the dryer line and the family unit circuit. 3 prong dryer cord diagram
Since the Code change, dryers must be set up with isolated nonpartisan and ground wires, which requires the utilization of 4-prong electrical strings connected to 4-opening outlets. Additionally, all recently introduced dryer containers should now be 4-space. Mortgage holders moving into a more up to date home regularly find that the 4-space dryer outlet doesn’t fit a more seasoned dryer that has a 3-prong rope.
Note: It’s as yet legitimate to utilize a dryer with a 3-prong rope and a more seasoned style container. For instance, on the off chance that you purchase another dryer set up for a 4-prong string, you can supplant the string with a 3-prong adaptation to fit a 3-opening container in your home. To do this implies following a technique like this task, however in switch—evacuating the 4-prong rope and introducing a 3-prong line.
What Is the Difference in Wiring?
The key contrast in the wiring arrangement between 3-prong and 4-prong ropes is that with the more seasoned arrangement, the 3-prong string has just two hot wires and one impartial wire—there is no different ground wire. In this manner, the dryer’s unbiased was attached to the ground association on the metal instance of the dryer.
A 4-prong string, conversely, has a different ground wire, which implies that the dryer’s unbiased and ground ought not be associated together. When you convert from the 3-prong to the 4-prong arrangement, you should ensure that the dryer’s unbiased terminal isn’t associated with the case ground. 3 prong dryer cord diagram
Since you are not taking a shot at real circuit wires while introducing the string, this is a sheltered undertaking. In any case, it is significant that the wire associations you make when appending the string to the apparatus be right and secure. Free associations can prompt shortcircuits and starting once the apparatus is connected for use.
- Give a decent pull on each wire as you complete the association with ensure it is secure.
- Always connect the strain-help fitting. This will assuage weight on the wire associations that can happen when the machine is moved around.
- Warning: Never plug in a dryer line except if it’s completely associated with the dryer. Connecting a line sends 240 volts of power to the uncovered wire parts of the bargains. In the event that the finishes contact together or contact you, they’ll make a possibly deadly cut off.
Instruments and Materials You Will Need
- Phillips screwdriver
- Nut driver or attachment wrench (as required)
- UL-recorded, 30-amp, 4-prong dryer string
- Strain-alleviation fitting for 4-prong string
- Adjustable forceps (discretionary).3 prong dryer cord diagram
