How often should you test portable GFCIs?

Testing portable GFCIs (Ground Fault Circuit Interrupters) before each use is crucial to ensure their proper functioning and safety. GFCIs are designed to protect individuals from electrical shock by monitoring the electrical current flowing through a circuit. If there is any imbalance, typically caused by current leakage through a person's body, the GFCI quickly shuts off the power.

By testing the GFCI each time it is used, you confirm that the device is operational and can effectively prevent shocks. This practice is especially important in environments where moisture or wet conditions are common, as these situations increase the risk of electrical hazards. Regular testing helps to establish a safety routine and reinforces awareness of electrical safety measures.

Other suggested frequencies, such as monthly or biannually, would not be sufficient to ensure safety for each specific use, as situations and conditions can vary significantly from one use to the next. Relying on infrequent testing could lead to using a faulty GFCI, increasing the risk of electrical accidents.
