A standard temperature control enclosure contains a switching contactor rated to hold a maximum of only two or three electric heaters. If there is a larger quantity of heaters or the total current draw of the heaters exceeds 48-amps, the NEC code requires customers to install branch wiring with circuit protection. Process Technology (Willoughby, OH) now provides a cULus listed Branch Fusing Enclosure customized for your exact heater/control combinations. This will ensure that your heater/control circuitry is protected according to normal code requirements.
