The Oxbox 5JAYHTR1P20BKA is an electric heat kit designed for use with compatible Oxbox package units. Rated at approximately 20 kilowatts of electric heat output, this kit provides supplemental or primary resistance heating capacity within a packaged HVAC system. Oxbox is a Trane brand, and this accessory is engineered to integrate with Oxbox package unit platforms, including models specified for the R-454B refrigerant system. Licensed HVAC technicians install this kit as part of a complete packaged system configuration, either at initial installation or as an add-on upgrade to an existing compatible unit.
This electric heat kit is intended for residential and light commercial packaged unit applications where electric resistance heat is the preferred or required heating source. It is suited for installations where gas heat is not available or practical. The 5JAYHTR1P20BKA is noted for compatibility with Oxbox R-454B package units, making it relevant to newer refrigerant-compliant system installations. Consult the specific package unit model documentation to confirm fitment before ordering.
Noted for use with Oxbox R-454B package units. Verify compatibility with the specific package unit model number prior to installation. Consult the package unit submittal documentation or the Oxbox installer guide for confirmed fitment.
Installation must be performed by a licensed HVAC technician in accordance with applicable local codes and the National Electrical Code (NEC). Disconnect and lock out all power to the package unit before beginning any electrical heat kit installation. Follow the package unit manufacturer's installation guide for proper kit mounting, high-voltage wiring connections, and breaker sizing — minimum branch circuit ampacity and maximum overcurrent protection ratings vary by unit configuration and must be confirmed from unit documentation before installing the circuit breaker or fusing.
