Portable Power Distribution Purpose and Use The MPD-480.3P-30KVA-240V.3P-70A portable power distribution system gives operators the ability to power their 240V equipment from a single system. On the primary side, operators connect 480 volt using a customer provided cord. On the secondary side, operators connect to one 4100R9W receptacle for three phase 240V equipment.
Operation: A customer provided cord brings 480V three phase power to the NEMA 3R 60-amp 480V three phase primary disconnect, which contains three 50-amp time delay fuses and passes 480V three phase through to the transformer. The NEMA 3R 30 KVA transformer converts 480V three phase power to 240/208-120V three phase and passes the current to the secondary side. The secondary side of the transformer feeds a NEMA 3R 100-amp 240V three phase secondary disconnect. This secondary side contains three 70-amp time delay fuses protecting one 240V 4100R9W receptacle. 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 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 allows easy lifting with cable or chain hooks. This can be replaced with stainless 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.
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.
