Portable Power Distribution Purpose and Use: The MPD-480.3P-30KVA-208Y.120-8X1P.20A-2X3P.50A-MOD1 portable power distribution system gives operators the ability to power their 208 volt and 120 volt equipment from a single system. On the primary side, operators connect 480 volt using a Meltric DR150 pin/sleeve male inlet. On the secondary side, two Meltric DR100 pin/sleeve receptacles for 208V equipment and eight 5-20R duplex GFCI receptacles for 120V equipment are available. All receptacles are equipped with weatherproof covers. This unit`s transformer is resin encapsulated.

Operation: A 150-amp, 600V rated Meltric DR150 pin/sleeve male inlet brings three-phase 480 V power to the NEMA 3R 60-amp, three-phase 480 V primary disconnect, which contains three 50-amp time delay fuses, and passes power through to the resin encapsulated transformer. The NEMA 3R 30 kVA transformer converts 480 V to three-phase 208Y/120 V, 60 Hz and passes the current to the secondary side. The secondary side of the transformer is equipped with a 100-amp, three-phase 208Y/120 V main circuit breaker panel. This panel contains two, 50-amp 3-pole 250 V breakers protecting two, 100-amp 600 V rated Meltric DR100 pin/sleeve receptacles and eight, 20-amp 1-pole 125 V breakers protecting eight, 20-amp 125 V 5-20R duplex 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.

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.
