The maximum length for a built-in dishwasher is specified in NEC clause 422.16(B)(2). Which statement reflects that limit?

Explanation:
The limit being tested is how far the built-in dishwasher’s power connection can extend into the cabinet space. NEC 422.16(B)(2) sets a maximum length for that connection to ensure the cord or conducting path can be routed safely inside typical kitchen cabinetry, with proper strain relief and no undue stress on terminations or interference with other components. The permitted maximum is 78 inches, which balances enough reach in common layouts with the need to keep wiring within safe, organized bounds. If more length is required, the installation should use a fixed wiring method or an approved in-cabinet receptacle setup rather than exceeding the listed maximum, to maintain electrical safety and reliability.
