Just a question out of pure curiosity.

New dishwasher installation, manual calls for a 20 amp breaker. No problem,
run 12Ga/2 (with ground ) Romex from breaker to J-Box, Run 12Ga/2 (with
ground ) BMX up to dishwasher. Open dishwasher electrical cover and it has
16Ga wire?????

So if code requires 12Ga for a 20 amp circuit how can the UL/CSA labeled
Kenmore dishwasher have 16GA wire for the final connection. Same thing with
the garbage disposal system.

Any thoughts on this one?
