High Power GFCI by TRC and Southwire

Technology Research High Power HD-Pro Ground Fault Interrupters from Sords Electric

TRC HD-Pro Southwire High Power GFCI/ELCI Ground Fault 

With the  TRC HD-PRO Series heavy duty, high power ground fault interrupters (GFCIs) you can feel safe around electrical equipment used in wet environments.  Single and three phase models are available for pumps, motors, welders, pressure washers, portable conveyers, hoists, mining tools and a host of high powered machinery.  All HD-PRO models automatically reset after interruption and restoration of power, but will trip on detection of hazardous ground fault conditions.

TRC Hd-Pro GFCI's are available in 120V, 30A to 600V, 100A.

TRC engineered HD-PRO models with an adjustable trip level selector, HD-PRO 6.10.30 and HD-PRO 10.30.50.  This unique design allows the flexibility to select and lock in a trip level of 6, 10 or 30mA, or 10, 30 or 50mA, customizing each model for the specific type of equipment to maximize protection while avoiding unwanted tripping.

TRC engineers designed the HD-PRO models specifically for high current, rugged environments and these models are field-proven in all kinds of tough applications. The entire HD-PRO family (120V/30A to 600V/80A) is designed to trip within 25 milliseconds after ground fault detection at an adjustable selected trip level of 6, 10 or 30 mA.

Before the development of the HD-PRO Series, facilities with high current – high voltage equipment or three phase systems employed expensive ground fault breakers at the source of the branch circuit, or went without ground fault protection, leaving personnel and equipment unprotected.

Circuit breakers can withstand high current levels but have short mechanical lives and were not designed for switching duty. Localized ground faults, with circuit breakers, either shut down the whole branch circuit or were overloaded because the available devices were not portable and were often too costly.

The HD-PRO Series utilizes contactors that are fully rated for motor switching demands. In addition to being far less expensive than three phase breakers, the HD-PRO models protect expensive high current – high voltage equipment at the point of use while offering substantial shock protection for personnel.

TRC is an internationally recognized leader in electrical safety products that protect equipment, prevent electrical fires and protect against electrocution and serious injury from electrical shock.

Why use Ground Fault:

A “Ground Fault” is a dangerous electrical condition where current flows unintentionally between a live conductor and ground. A severe or fatal electric shock can occur when a user touches the pressure washer if the machine is ungrounded. This could happen if the power cord to extension cord connections become wet or a fault exists within the pressure washer’s sophisticated electrical system. GFCI’s prevent possible electrocution and equipment damage due to electrical malfunction. Once the GFCI trips, the power is interrupted, stopping the pressure washer power and making it electrically safe for people and preventing costly equipment damage.

Avoiding electrical accidents and equipment damage are keys to reducing liability and increasing productivity. Minimum ground fault, GFCI, protection can be incorporated into the main power disconnect device and could be considered adequate for the entire system. However, in such a design, any downstream ground fault could trip the main protective device resulting in a complete substation power outage. The NEC's purpose, in its own words, is "the practical safeguarding of persons and property…but not necessarily efficient, convenient, or …for good service…" (Article 90.1A, B). In other words, system reliability is left to common sense and good engineering design practices. For this reason ground fault, GFCI, protection of the circuit may be highly desirable and recommended for reliable and continuous operation.

Technology Research Corporation (TRC) is a leading manufacturer of electrical safety products. Based in Clearwater, Florida, TRC designs, develops and manufactures products that prevent electrical fires and protect people and pets from electrocution and serious injury caused by electrical shock.
