Final Answer:
The manufacturer recommended maximum length of a GFCI protected branch circuit is typically 150 feet.
Step-by-step explanation:
Ground Fault Circuit Interrupter (GFCI) protection is essential for electrical safety, especially in areas where water is present. The manufacturer's recommended maximum length for a GFCI protected branch circuit is generally around 150 feet. Beyond this distance, the risk of voltage drop and potential issues with the GFCI's proper operation may increase.
GFCIs are designed to quickly disconnect the circuit if a ground fault is detected, preventing electric shock hazards. However, factors such as wire resistance and impedance could impact the effectiveness of GFCI protection over longer distances. Therefore, adhering to the manufacturer's guidelines regarding circuit length is crucial to ensure the reliable operation of GFCI protection.
