NEC 2011 705.12(D)(7) Inverter Output Connection
Mandates that inverter breakers in panelboards be placed at the opposite end from the main feeder to avoid overloading busbars.
Requires a permanent warning label: “INVERTER OUTPUT CONNECTION—DO NOT RELOCATE THIS OVERCURRENT DEVICE.” Ensures anyone servicing or inspecting the panel cannot accidentally move the protective device, minimizing risk of overheating, fire, or improper system configuration. This requirement protects electrical integrity and improves maintenance safety for utility-interactive PV systems.
