- When installing a product that can use a three or four wire connection, where does the white wire go?
- Is three or four wires preferred for installation on a 240V or 208V electrical supply?
For any Wolf products that can use a three- or four-wire connection, either a three- or four-wire installation is acceptable. One is not preferred over the other.
- If using a three-wire connection, the white neutral wire is typically capped off and unused. Which ever wiring configuration is in the home (three or four wires) is suitable for connecting the unit.
- Terminal blocks that can accommodate either three- or four-wire connections will have a "jumper" between the neutral and ground connectors.
- Leave the jumper intact if making a three-wire connection.
- Cut the jumper if making a four-wire connection.
- Failure to do so can result in electronic issues.
Refer to the product Installation Guide for further information.
