The Larson Electronics
MGS-45KVA-40X120 power distribution substation converts 480 VAC three phase
electrical current into 3 phase 208Y/120V AC. This unit provides operators the
ability to safely tap into and distribute 480V AC power from a variety of
sources including generators and direct grid power.
Operation: The 25`
6/4 SOOW line-in cord brings 480V three phase power to the 60-amp 480V 3-phase
primary disconnect, which contains three 60-amp time-delay fuses protecting
protecting the 45 KVA transformer. The NEMA 3R 45 KVA transformer converts 480V
three phase power to 208Y/120V and passes the current to the secondary panel.
The secondary side of the transformer feeds a NEMA 3R 150-amp main breaker
panel. This secondary panel contains twenty 20-amp 120V breakers protecting
forty 120V 20-amp 5-20R duplex receptacles. All receptacles are equipped with

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 polyurethane casters, and a top located lifting eyelet 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.
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.~
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.
