RELIANCE

Reliance is a brand specializing in power management and transfer equipment for backup generator systems. The product line includes manual transfer switches, power inlet boxes, power cords, appliance load testers, and receptacle testers with GFCI functionality. These components are designed for residential and light commercial applications where temporary or standby generator power must be safely connected to a building's electrical system. Reliance manual transfer switches are prewired units rated for single-phase, 125/250V AC service, available in current ratings such as 30 A (model 30310A). They include integrated meters for load monitoring and are intended for use with specific inlet boxes and cords. Power inlet boxes from Reliance are offered in both steel and ABS enclosures, with NEMA L14-30 receptacles or universal CS6375 configurations, rated at 30 A or 50 A. Enclosure types include Type 3R for outdoor use. The brand also supplies generator power cords, such as the PC3020, a 20-foot, 10 AWG cord rated for 125/250V AC and 30 A, designed to connect between a transfer switch and inlet box. For diagnostic purposes, Reliance offers the THP103 appliance load tester, a digital single-phase meter measuring up to 125 V AC, and the THP102P receptacle tester with GFCI detection, using a 5-15P plug and light indicators. These products are built to standard electrical ratings and are intended for straightforward installation by qualified electricians. 3G Electric stocks multiple Reliance SKUs, covering transfer switches, inlet boxes, cords, and testers, supporting procurement for maintenance and engineering teams who need reliable backup power components. The brand's focus is on functional, code-compliant equipment without proprietary features, making it suitable for standardized installations.
