How often should GFCIs be tested for proper working condition?

GFCIs, or Ground Fault Circuit Interrupters, are vital safety devices designed to protect against electrical shock and reduce the risk of electrical fires. It's essential to ensure that these devices are functioning properly. Testing GFCIs once a month is a standard recommendation because it allows for the regular verification that the device is operational, helping to identify any potential issues before they lead to inadequate protection.

Monthly testing ensures that users maintain a consistent routine, allowing them to catch malfunctions or failures that might not be evident during occasional or less frequent checks. Since GFCIs are often installed in areas vulnerable to moisture, like bathrooms and kitchens, where the risk of ground faults is increased, the frequency of testing becomes even more critical to ensure safety. Regular testing helps to ensure that the protection against ground faults remains intact, providing peace of mind for users.
