Sensor provides automatic on/off based on ambient lighting. Energy-efficient guide light uses approx. 1W of electricity - no bulbs to replace.
Saves space by eliminating the need to use an outlet for a plug-in night light.
For an added layer of protection, the GFCI regularly conducts an automatic internal test to confirm that it can respond to a ground fault.
Patented lockout action prevents reset if GFCI is damaged and cannot respond to a ground fault.
Slim, shallow design - reduced depth makes it easier to install.

BRING ELECTRICAL SAFETY WHEReVER YOU GO: this GFCI portable plug-in adapter is of a nifty size which you can easily put into your toolbox, or move it from room to room with your power tools or portable appliances.
PROTECTS YOU FROM DANGEROUS POWER SURGES: this portable GFCI plug has built-in electronic circuitry that will shut off power in 25/1000 of a second if a ground fault is detected, thereby preventing current from flowing through you which can be deadly.
VERSATILE PORTABLE GFCI PLUG: this portable GFCI plug is suitable for indoor use in your bathroom, kitchen, basement and garage.
UL LISTED AND CSA CERTIFIED: having been UL listed and CSA certified, rest assured that this portable GFCI plug is very safe to use.
comes with patented ground fault sensing technology.

Offers protection from electrical fires and shocks in one device. Interrupts power if a potentially dangerous arc-fault or ground fault is detected.
Periodically conducts an automatic internal test to confirm that GFCI protected power is available.
Patented lockout action prevents reset if damaged and cannot respond to an arc-fault or ground fault.
Replaces a standard receptacle and has test and reset buttons on face for localized testing and resetting.
Can be used to meet code requirements for AFCI and GFCI protection in residential kitchens and laundry areas.
Tamper-Resistant – shutter mechanism inside the receptacle helps prevent access to the contacts unless ....

A4988 driver board widely used in 3D printers and small CNC machines.
Simple step and direction control interface.
Thermal protection, over-current protection, ground fault protection.
Five different step resolutions: full-step, half-step, quarter-step, eighth-step, and sixteenth-step.
Adjustable current control lets you set the maximum current output with a potentiometer, which lets you use voltages above your stepper motor’s....

Provides continuous ground fault protection – detects and trips on actual ground fault even when self-test is being conducted.
For an added layer of protection, the GFCI regularly conducts an automatic internal test to confirm that it can respond to a ground fault.
Status indicator light shows power and protection status as well as indication of line/load reversal.
Patented lockout action prevents reset if GFCI is damaged and cannot respond to a ground fault.
Terminals allow for easy wiring options – back and side wire capable.
Slim, shallow design – reduced depth makes it easier to install.
Compatible with all Decora devices and wallplates.
