Yellow Jacket 1 Outlet GFCI
A convenient way to provide Ground Fault Circuit Interrupter (GFCI) protection when only Non-GFCI receptacle outlets are available, this plug-in device will provide Class A (4-6 ma) personnel protection against ground fault current. Although the instructions make reference to operating at several amperes of Ground Fault current, later in the instructions reference is made, correctly, to the 6-ma trip level. Easily used by plugging into an available receptacle outlet, it is configured to permit use in a duplex receptacle without blocking the unused half of the receptacle. Intended for temporary use, upon plugging it into a receptacle outlet, it is necessary to press the “reset” button to energize the output of the device. A red indicator line is provided on the reset button, to permit visual indication that the device has been properly reset. A “test” button is provided to exercise the detection circuitry to verify that the device is still functioning. The “test” and “reset” functions are marked on the body of the device, but the molded lettering is somewhat difficult to read. Initially, the fit of blades into the output side of the device is rather tight, but should loosen up somewhat with use. It is not intended for use in wet areas, which will limit its use to those locations where an inside receptacle outlet or one sheltered from rain is available. While it can be used plugged INTO an extension cord, Ground Fault protection will be provided only downstream of the device. Rated, electrically, for 15 amps (1800 watts) at 120 volts, 60 Hz, it can withstand and overload of six (6) times the current rating. Environmentally, it is rated for use between -35 degrees C to 66 degrees C (-31 degrees F to 150.8 degrees F), which should be adequate for most applications. This device will be useful when the only source of power is non-GFCI receptacle outlet. As the device has a three-pin (Line-Neutral-Ground) configuration, use in an ungrounded receptacle outlet would require an adapter. Such use would not provide grounding but would still allow the GFCI protection to operate (the grounding conductor is not required for a GFCI device to function).
Pros: Compact, Easy Installation, Easy to Use, does not block unused receptacle
Cons: very tight fit for attachment plug blades, instructions could be written better.
