25 KVA Temporary Power Distribution - 480V to 120/240V 1PH - (1) 480V (1) 240V (6) 120V Receptacles

Part # MGL-480.3P-1X480.20-25KVA-6X120.20-1X240.20    Price: $5,730.89

Spec Sheet   


Made in Texas

The Larson Electronics MGL-480.3P-1X480.20-25KVA-6X120.20-1X240.20 temporary power distribution system converts 480V AC three phase current to 120/240V single phase. This power distribution system provides operators the ability to safely tap into and distribute 480V power from a variety of sources including generators and direct grid power.


Portable Power Distribution Purpose and Use The MGL-480.3P-1X480.20-25KVA-6X120.20-1X240.20 portable power distribution system gives operators the ability to power their 480V, 240V and 120V equipment from a single system. On the primary side, operators connect 480 volt using a customer provided cord and to one, L16-20C twist lock receptacle for 480V equipment. On the secondary side, operators connect to one, L14-20R receptacle for 240V equipment and to six, GFCI duplex receptacles for 120V equipment.

Operation: A customer provided cord brings 480V three phase power to the NEMA 3R 40-amp primary disconnect, which contains one, L16-20C 480V receptacle, and passes 480V through to the second NEMA 3R 60-amp primary disconnect. The second disconnect on the primary side passes 480V through to the transformer. The NEMA 3R 25 KVA transformer converts 480V three phase power to 120/240V single phase and passes the current to the secondary panel. The secondary side of the transformer feeds a NEMA 3R 62.5-amp 120/240V single phase main lug only circuit breaker enclosure, which contains one, 20-amp 240V breaker protecting one, L14-20R 240V receptacle and six, 20-amp 120V breakers protecting six, GFCI duplex 120V receptacles. 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 center/distribution assembly is mounted to a powder coated steel, dolly cart style, frame resulting in an extremely stable, durable, and mobile power distribution platform. Two run-flat rubber tires and a dolly cart style mounting platform provides easier substation mobility, and a center point lift point 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.

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. If this model does not meet your needs, please contact us at 1-800-369-6671 or to discuss your specific requirements.
