The MGL-30KVA-4X120.20A-1X208.50A-E18 portable power distribution substation converts three phase, 480 VAC electrical current to 120V AC and 208V AC via a 30K VA transformer (480V to 208Y/120, 60Hz). 10 feet of 4/4 SOOW line-in cable is included to connect the substation to a primary 480V primary power supply. A fused disconnect provides primary line-in protection and supplies primary power to the 30 KVA transformer.
Secondary current is wired to a 120/208V, single phase, 100-amp load center with main breaker for circuit protection. 120/208V line-out protection is provided by three 20-amp, 125V, single pole breakers and one 50-amp, 250V, 2 pole breaker.
Connection for 208/120V AC is through receptacles mounted on the side of the load center. Receptacles include four 20-amp, 125V, GFCI waterproof duplex receptacles and one 50-amp, 250V receptacle. The load center is rated NEMA 3R, the transformer is potted and the entire system is built and certified to UL 1640 standards.
The transformer and load center/distribution assembly is mounted to a powder coated steel, dolly cart style frame resulting in an extremely stable, durable, and mobile power distribution platform. Two run-flat rubber tires and a dolly cart style mounting platform provides easier substation mobility, and a center point lift point allows easy lifting with cable or chain hooks.
This temporary power distribution solution can be modified to meet the needs of job-site receptacle requirements. Units are available up to 150 KVA, and can be equipped with skids or trailer mounted.
This power distribution system is NEMA 3R rated and ideal for indoor/outdoor use and applications including but not limited to; construction sites, plant maintenance, plant turnarounds, shows, exhibits and shipyard operations.
