7.5 KVA Temporary Power Distribution - 480V Transformer - (2) 120V GFCI Outlets & (1) 240V Outlets

Part # MGL7.5-480-2X120.20-1X240.20     Price: $5,310.50

Spec Sheet   

Made in the USA

The Larson Electronics MGL7.5-480-2X120.20-1X240.20 temporary power distribution system transforms 480V 3 phase power to single phase 120V AC and 240V AC 60hz. This power distribution system provides operators the ability to safely tap into and distribute 480VAC power from a variety of sources including generators and direct grid power. This portable substation is suitable for outdoor applications, with a fully potted transformer and NEMA 3R load center. This power distribution system is configured to transform 480V 3 phase to 120/240 Delta, so up to 5% of the capacity can be used for lighting loads as well.


The MGL7.5-480-2X120.20-1X240.20 temporary power distribution system provides a safe and reliable way for operators in industrial settings to tap into and utilize power sources independently of the work area. This unit provides an effective power distribution system for operators performing plant turnarounds, maintenance and cleaning in hazardous areas, equipment installations and repairs, and any activities requiring an alternative to native power sources. This portable transformer is designed to operate with 480v, three phase, 60hz which it then steps down to 120/240 VAC. The power distribution system on this portable substation makes 120VAC available via two 20amp, 120v GFCI protected 5-20 receptacles and 240VAC available via a single L6-20 outlet.

The MGL7.5-480-2X120.20-1X240.20 portable power distribution substation converts 480 VAC electrical current to single phase 120V AC via a 7.5kva transformer (480v to 120V/204V 1ph, 60hz). 25 foot of #4 Type W line-in power cord with a L16-30 30-amp, 480v, 3 phase 4 wire male plug is included to connect the substation to a primary 480v power supply. A 10-amp fused disconnect provides primary line protection and supplies primary power to the 7.5kva transformer.

Secondary current is wired to a 120v, single phase, 100-amp NEMA 3R load center with main breaker for circuit protection. 120 Volt line out protection is provided by two 20-amp, 125 Volt, 1 pole breakers. Receptacles include two 20-amp, 120v, GFCI waterproof 5-20 receptacles. A 20-ampm 240 VAC breaker protects a L6-20 receptacle with waterproof cover.

The transformer and load center/distribution assembly is mounted to a standard (powder coated) steel cart style frame resulting in an extremely stable, durable, and mobile power distribution platform. Two rubber tires and a cart style mounting platform provides easier substation mobility, and a center point lift eye allows easy lifting with cable or chain hooks. This temporary power distribution solution can be modified to meet the needs of job-site receptacle requirements. Units are available up to 150kva, and can be equipped with skids or trailer mounted.


This power distribution system is NEMA 3R rated and ideal for indoor/outdoor use and applications including but not limited to; construction sites, plant maintenance, plant turnarounds, hazardous location operations, shows, exhibits, and shipyard operations. These temporary power distribution systems are popularly used for HAZLOC applications where external power sources are often necessary and work well in combination with explosion proof lights and equipment.

Larson Electronics is a manufacturer and as such can build portable transformer systems to your specifications. Although we carry several models of power distribution transformers, 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.
