Legrand Pass & Seymour's Ground Continuity Monitor
Legrand Pass & Seymour’s watertight ground continuity monitoring products have a dual bright blue or red LED indicator in a transparent thermoplastic elastomer. This allows the lights to be seen while providing a NEMA 6P/IP67 rating. The blue light indicates the upstream circuit is grounded and wired properly from the receptacle back to the panel and from the cordset back to the plug. The red light indicates the open ground/reversed polarity of line conductor power is present in the device. If no light is indicated, then there is no power, open hot or neutral conductor, or hot/ground reversal.
