Portable Power Distribution Purpose and Use: The MPD-480V-75KVA-300MB-120.240-6X50A.50FT portable power distribution system gives operators the ability to power their 120/240V single phase equipment from a single system. On the primary side, operators connect 480 volt three phase using a customer provided cord. On the secondary side, operators connect to six CS6364C twist-lock connectors with 50` SOOW whips for 120/240V single phase equipment.
Operation: A customer provided cord brings 480V three phase power to the NEMA 3R 200-amp primary disconnect and passes 480V single phase through to the transformer. The NEMA 3R 75 KVA transformer converts 480V single phase power to 120/240V single phase and passes the current to the secondary panel. The secondary side of the transformer feeds a NEMA 3R 300-amp, 120/240V main breaker panel, which contains six 50-amp breakers protecting six CS6364C 120/240V twist-lock connectors with 50` SOOW whips.
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 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 can be replaced for an additional cost with stainless steel, hot dip galvanized steel, or aluminum depending on the customer’s needs. Larger units are available upon request and can be equipped with skids or trailer mounted.
Certification: Larson Electronics is a UL 1640 panel shop and certified to build portable power distribution systems. All units are built in accordance to NFPA 70 (National Electric Code) and certified to UL 1640. All equipment is NEMA 3R rated for indoor and outdoor use and provide a degree of protection against dirt, water, and ice. NEMA 4 and NEMA 4X equipment can be equipped upon request.
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.
