Made in the USA

The Larson Electronics MGS-15KVA-120-240-30AFT heavy duty power transformer substation converts 480VAC electrical current to 120/240VAC single phase. This unit provides operators the ability to safely tap into and distribute 480VAC power from a variety of sources including generators and direct grid power. Includes ADR3034 30A receptacle and ACP3034 30A plug with cord for 480V feed thru applications.


The MGS-15KVA-120-240-30AFT transformer provides a safe and effective way for operators in industrial settings to tap into and utilize power sources independently of the work area. This unit provides an effective power source 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 unit is designed to operate with 480VAC which it then steps down to 120/240VAC. This transformer makes 120VAC available via ten 125V 520R-GFCI protected receptacles and 240VAC available via two 250V L6-30R twist-locks. Also included with this unit is a 480V ADR3034 receptacle (mating plug with 25 foot whip included) for welding substations or similar applications.

The MGS-15KVA-120-240-30AFT converts 480VAC to 120/240VAC single phase and provides 15KVA capacity. Protection is provided through the use of ten 125V 520R-GFCI protected outlets. 20 feet of #6 Type W line in cord connects to a 60A disconnect switch fused @ 40A controlling a 15KVA transformer and to a 30A disconnect switch fused @30A controlling a ADR3034 30A receptacle and ACP3034 30A plug with 25 feet of SOOW cord allows operators to utlize a feed through power option as well for 480V welders and equipment.

The transformer and distribution assembly is mounted onto a rugged frame with integrated skid mounting, no flat all terrain tires for easy mobility and a top located eyelet to allow easy transport. This unit is ideal for use in applications including but not limited to, plant maintenance, hazardous location operations, as a welding station, shows and exhibits and marine applications. These units are popularly used in hazardous locations where external power sources are often necessary and work well in combination with explosion proof lights.

12/20/11Temporary Power Distribution Within Industrial Construction Projects

The electrical power utilized by contractors often starts out as a primary high voltage connection to the local grid. These voltages vary according to the utilities involved and can exceed 11,000 volts. The first step is to reduce this to manageable voltages through the use of temporary power substations which reduce this current to 480VAC. Once this is achieved, the 480VAC power can be fed into distribution panels for routing through the structure. To provide power to every location within the [...]
