GFCI receptacle updated

The company that brought out the first ground-fault circuit interrupters (GFCI) 30 years ago, has improved the design so that it is even safer.

The new receptacles from Pass & Seymour/Legrand, Syracuse, N.Y. (www.passand seymour.com), feature SafeLock protection. It cuts off power to the receptacle if critical components are damaged or ground-fault protection is otherwise lost. It also protects better against power surges, resists corrosion, and is less likely to trip falsely due to noise on electrical power lines. They are configured so that if they are miswired, they cannot be reset, preventing line-load reversals. And they have a trip indicator light for convenience. The receptacles meet UL 943 (Standard for safety for GFCI) that took affect last year.
