Us guys "back East" wire disposals, dishwashers compactors etc. as permitted per Article 422.16(A) or if the appliance comes with a cord we provide a receptacle and properly sized circuit for it. This would be probably the rule for most of the State of Michigan. Okay, maybe we ain't "back East" but were mighty close to it. Maybe commerical equipment disposals, dishwashers that come without a cord are hard wired but most residential installations are cord connected. Don't get me wrong, I like cord and cap connections for some appliances because if and that's a big IF the electrician installs the cord there's a better chance it's done correctly and the receptacle is wired correctly and it's a better comfort level on the part of the inspector. It's not uncommon to see the cord by a non-electrician and it's sans a connector. That's when I write a violation to the electrical contractor.
