* Ready to mount. Step Plate eliminates double-nutting. * Diagnostic circuit-LED. indicates the reason for service,allowing for quick,easy trouble-shooting. * Primary wiring requirements of a NON-SCGEP-with the added safety of secondary ground fault protection. * Service button-for easy troubleshooting of ground faults and primary wiring problems.Overrides the SCGFP for up to 30 minutes. * Open circuit protection-when the no-loading output and even if connected to the input power or any loading tube is damaged,with the role of protector,there will be no voltage output in the terminal power. * Secondly circuit ground fault protection(SCGFP)-disables unit upon detection of arcs to ground in compliance with UL2161 and NEC requirements. * The earth leakage protection-when have the leakage,protector will transient response. * Easy wiring methods-virtual ground and series wiring methods * User friendly-Adapts to most grounding situations. * Bypass voltage or super lower voltage protecting function. * Can be used in flashing/dimming applications.
