An eight-pole, twenty-ampere electrically held contactor includes a hand-off-auto switch and on/off pilot lights, with the coil voltage coordinated with the building automation system contractor. The contactor is located in the main electrical room and labeled with an engraved nameplate reading "HEAT TRACE". Control input feeds from the building automation system in accordance with sequence of operations specifications, utilizing necessary relays, conductors, and connections for a fully functional system. Branch circuits feed out to the roof heat trace from the panel per plans.
