Testing GFCIs on a monthly basis is a good idea that is sometimes forgotten. Underwriters laboratories (UL) suggests that GFCI Devices be tested every 30 days after installation to ensure they are properly working. Now the new self-test & lockout feature enables the GFCI to automatically and continuously test itself to ensure that it is working properly. If it is detected that the device has been compromised, the device trips itself and locks out the device, reducing the possibility of the homeowner incorrectly assuming that the device was tripped to prevent a ground fault. This effortless system guarantees that only the best protection is given to your home at all times. The self test and lockout feature meets NEC 2014 requirements.
