by Shane Henson — October 1, 2012—Larson Electronics’ Magnalight.com has released a temporary power distribution system developed to provide a safe and reliable way for operators in construction and industrial settings to tap into and utilize power sources independently of the work area.
The MGL7-480-2X120V Temporary Power Distribution System is ideal for industrial work operations such as plant turnarounds and new construction and allows operators to safely tap into three-phase 480 VAC power sources to provide power for equipment and lighting that requires 120 VAC, says Larson Electronics’ Magnalight.com, distributor of a wide variety of power distribution substations.
This unit connects to the primary 480-volt power source through an included 25-foot long power cord fitted with a 30amp, 480v, 3-phase, 4-wire male plug. The main primary supply is controlled and protected by an on/off switch with fused disconnect for secure and safe operation. The 7.5KVA transformer steps the primary 480-volt current down to single-phase 120 VAC , which is fed through a 120-volt, single-phase load center protected by a single 125amp main breaker.
Secondary output is made available through two 20amp, 120-volt, GFI-protected waterproof duplex receptacles. The load center and controls on this heavy-duty step down transformer are housed within a Nema 4/12-rated enclosure for secure and reliable protection from the elements, and an optional glass door can be included to provide for easy inspection of the load center during maintenance.
In addition, this temporary power substation is easy to set up and easy to move thanks to a heavy-duty mounting cart fabricated of steel and fitted with two rugged rubber tires. Once on-site, operators can simply roll this unit into the desired position and connect to the main power line, or move the unit as work progresses. The durable steel frame is grounded to the transformer and load center assembly, and features a heavy-duty finish to resist help rust and corrosion. Also included is a rear-mounted cord rack that provides easy storage of the 25-foot long power cord during transport.
