The Larson Electronics MGS-SS-2X480.100A-45KVA-208.120-2X50A-2X30A-20X20A power distribution substation converts 480 VAC three phase electrical current into 3 phase 208Y/120V AC. This unit provides operators the ability to safely tap into and distribute 480V AC power from a variety of sources including generators and direct grid power.
Operation: The customer provided line-in cord brings 480V three phase power to the NEMA 3R 250-amp 480V 3-phase primary panel, which contains two 100-amp breakers protecting two 4100R7W receptacles and one 80-amp breaker protecting the 45 KVA transformer. The NEMA 3R 45 KVA transformer converts 480V three phase power to 208Y/120V three phase and passes the current to the secondary panel. The secondary side of the transformer feeds a NEMA 3R 150-amp 208Y/120V 3-phase main breaker panel. This secondary panel contains two 50-amp breakers protecting two 50-amp CS6369 receptacles, two 30-amp breakers protecting two L5-30R receptacles, and ten 20-amp 120V breakers protecting twenty 120V 20-amp 5-20R duplex receptacles. All receptacles are equipped with weatherproof covers.

Protective Construction: Unlike many portable power distribution boxes made of plastic and utilizing thin gauge, low grade metals in their construction, this unit is designed for serious use and is ruggedly constructed to withstand demanding conditions and heavy duty industrial applications. The transformer and load assembly is mounted on a 3/16" thick stainless steel mounting platform and the load center/distribution assembly is mounted to the standard 2" x 2" x 1/8" square stainless steel tubing frame, resulting in an extremely stable, durable and well protected power distribution platform. This model is equipped with forklift skid pockets, locking polyurethane casters, and a top located lifting eyelet allows easy lifting with cable or chain hooks. This can be replaced with carbon steel, hot dip galvanized steel, or aluminum depending on the customer’s needs for an additional cost. Larger units are available upon request, and can be equipped with skids or trailer mounted.
Grounding: Transformer is grounded to the frame and we provide a grounding lug on the frame for the earth ground.
~Please check all motor loads for dual rated motors that will work 208 or 240.~
Applications: This power distribution system is ideal for indoor or outdoor use and applications including but not limited to, construction sites, plant maintenance, plant turnarounds, shows, exhibits, and shipyard operations. These power distribution systems are popularly used in applications where external power sources are often necessary. We also offer class rated transformers for use within explosion proof and hazardous location environments.
