Portable Power Distribution Purpose and Use: The MPD-480.3P.50AFT.TB-15KVA-1X208.2P.30A-6X120.1P.20A portable power distribution system gives operators the ability to power their 480 volt and 240 volt and 120 volt equipment from a single system. On the primary side, operators connect three phase 480V using 20` of #6 Type W cord with a 100-amp 4100P7W cord cap and to one Phoenix 1679427 terminal block 50-amp receptacle, protected by a Phoenix 1645480 housing, for 480V equipment. On the secondary side, operators may access one L6-30R receptacle for 240V equipment and six L5-20R GFCI duplex receptacles for 120V equipment. All receptacles are equipped with weatherproof covers.
Operation: A 20` #6 Type W cord with a 100-amp 4100P7W cord cap brings 480V three phase power to the NEMA 3R 60-amp 480V three phase primary disconnect, which contains three 50-amp time delay fuses protecting one Phoenix 1679427 terminal block 50-amp 830V-rated receptacle, protected by a Phoenix 1645480 housing, and passes 480V three phase to the second primary disconnect. The NEMA 3R 30-amp 480V three phase second primary disconnect, which contains three 20-amp time delay fuses, passes 480V three phase power to the transformer. The NEMA 3R 15 KVA transformer converts 480V three phase power to 208Y/120V three phase 60 Hz and passes the current to the secondary side. The secondary side features a 50-amp 208Y/120V three phase main lug only NEMA 3R panel, which contains one 30-amp 2-pole 250V breaker protecting one 30-amp 250V L6-30R receptacle and six 20-amp 1-pole 125V breakers protecting six 20-amp 125V L5-20R GFCI duplex 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.
Custom Built Systems Available: Larson Electronics is a manufacturer and we can build portable power distribution systems to your specifications. Although we carry several models of portable power distribution systems in stock, we can deliver custom ordered units almost as quickly as our prebuilt units.
