Portable Power Distribution Purpose and Use: The MPD-480V-2X60-25KVA-10X120.20-2X240.30 portable power distribution system gives operators the ability to power their 480V and 120/240V equipment from a single system. On the primary side, operators connect 480 volt using a 30` 2/4 Type W cord and to two 460R7W receptacles for 480V equipment. On the secondary side, operators connect to two L6-30R receptacles for 240V equipment and to ten duplex receptacles for 120V equipment. All receptacles are protected by weatherproof covers.
Operation: A 30` 2/4 Type W cable brings three phase 480V power to the NEMA 3R 150-amp 480V three phase primary panel, which contains three 3-pole 60-amp circuit breakers and two 60-amp 480V 460R7W receptacles, and passes 480V three phase through to the transformer. The NEMA 3R 25KVA transformer converts 480V single phase power to 120/240V single phase and passes the current to the secondary side. The secondary side of the transformer feeds a NEMA 3R 100-amp 120/240V single phase secondary panel. This secondary side contains two 2-pole 30-amp 250V breakers protecting two 30-amp 250V L6-30R receptacles and ten 1-pole 20-amp 125V breakers protecting ten 20-amp duplex 125V GFCI receptacles.
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 carbon steel mounting platform and the load center/distribution assembly is mounted to the standard 2" x 2" x 1/8" square carbon steel tubing frame, resulting in an extremely stable, durable and well protected power distribution platform. This model is equipped with forklift skid pockets, locking casters, and a top located lifting eyelet which 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.
