The connection style matters
QB cable-in/cable-out construction is used in specified panel and retrofit arrangements. The bus attachment, enclosure listing, neutral handling, and approved accessory set must match the equipment instructions; a similar handle or case is not proof of fit.
Confirm before energizing
Review the exact panel or enclosure label, system voltage, 10kA fault-current limit, branch conductor, neutral routing, and required AFCI coverage. Have a qualified electrician install the device and complete its test procedure.
