Portable Power Distribution Purpose and Use
The MGS-4803P.100A-PS-45KVA-208.1203P.150A-6XMG portable power distribution system gives operators the ability to power their 240 volt and 120 volt equipment from a single system. On the primary side, operators connect 480V line-in power via 20` of #4 Type W cord with a 100-amp 4100P7W cord cap. On the secondary side, operators connect to one HBL63CM69 receptacle for 240V equipment and to five HBL53CM62 receptacles for 120V equipment. All receptacles are equipped with in-use waterproof covers and all breakers on the secondary side feature GFCI protection.
Operation: The 20` #4 Type W line-in cord with a 100-amp 4100P7W cord cap brings 480V three phase power to the NEMA 3R 100-amp 480V three phase primary main circuit breaker panel, which contains one 70-amp 3-pole 480V breaker and passes power to the transformer. The NEMA 3R 45 KVA transformer converts three phase 480V AC to three phase 208Y/120V AC 60Hz and passes the current to the secondary panel. The secondary side of the transformer feeds a NEMA 3R 150-amp three phase 208Y/120V AC main circuit breaker panel. This secondary panel contains one 50-amp 2-pole 250V GFCI breaker protecting one 50-amp 125/250V HBL63CM69 receptacle and five 20-amp 1-pole 125V GFCI breakers protecting five 20-amp 125V HBL53CM62 receptacles.
Protective Construction: Unlike many portable power distribution boxes made of plastic and utilizing thin gauge, low grade metals in their construction, this galvanized 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.
