1.Trip threshold meets or exceeds UL requirements for tripping time.
2.UL Standard 943 Class A & UL498 for Receptacle.
3.Advanced electronics design provides superior resistance to electrical surges and over-voltages.
4.Standard copper parts are integrated stamping one-piece design to ensure stable work.
5.TEST and RESET button colors match device face (Red & blue buttons optional).
6.Standard thickness silver contacts ensure good contact.
7.Three colors led indicator light provides simple, intuitive feedback on power and protection status.
8.If the GFCI installed in correct wiring, the automatic detection function detects once within 3 seconds once power-on, and the red indicator flashes once in each internal detection cycle. Green led indicator will on once GFCI been reset, and the receptacle get power.
9.Please replace the GFCI if the red led indicator on and can not reset.
10.Side or internal screw-pressure-plate back wire with #10-#14 AWG solid or stranded copper wire.
11.Auto-Ground clip assures a positive ground to metal box.

If line/load reversed, the Green led indicator will on before GFCI been Reset, no power will be delivered to receptacle face.

The receptacle blocks access to the contacts unless a two- or three-prong plug is inserted.
