Product Description

The SPECO JB2 is a large junction box finished in Speco Blue, used to house and protect electrical wire connections in a variety of trade installations.

The JB2 is suited for use by electricians, HVAC technicians, and other trade professionals who require a reliable enclosure for wiring in residential or light commercial applications.

Installation Notes

Installation of junction boxes must be performed by a qualified electrician or licensed trade professional in accordance with the National Electrical Code (NEC) and applicable local codes. Always de-energize the circuit at the breaker panel and verify absence of voltage before making any wire connections inside the box. The box must remain accessible after installation per code requirements. Do not overfill the enclosure beyond its rated fill capacity.
