Which statement is true regarding mating connectors used for PV circuits?

Mating connectors used for photovoltaic (PV) circuits must be specifically rated for interrupting current to ensure safety and reliability in electrical systems. This is crucial as these connectors can experience fault conditions where current needs to be interrupted safely and effectively.

Connectors that are properly rated for interrupting current help to prevent electric arcs, which can pose serious safety hazards such as electrical fires or equipment damage. Ensuring that connectors meet these ratings supports compliance with the National Electrical Code and other relevant safety standards.

While other statements may touch on aspects like ease of access or marking, they do not address the critical safety aspect that comes from ensuring the connectors can handle interrupting current. Being rated for interrupting current is foundational for ensuring safe and efficient operation of PV circuits during normal functioning and abnormal conditions.
