Electric dryer cord change (3-wire to 4-wire or reverse)
Match the cord to the receptacle. With a 3-wire cord the neutral-to-cabinet ground strap (or green screw link) stays in place. With a 4-wire cord the strap is removed, the green wire goes to the cabinet ground screw and the white to the center neutral terminal only.
Before you start
- 240 V: unplug or turn off the breaker before opening the terminal cover.
- Do not overtighten terminal nuts on plastic blocks.
- Charred receptacle or cord: do not reuse; refer the receptacle to an electrician.
