Why this code exists

A cord connection makes servicing easy, but only if the cord is the right length and the receptacle is accessible instead of buried behind the unit.

The Code spells out cord length ranges and where the receptacle can be so the appliance can be unplugged and pulled for service without yanking the cord or fishing behind it.

For a dishwasher, the receptacle usually belongs in the sink cabinet next door, not directly behind the machine where you can never reach it.

When it applies

This covers cord-and-plug connection of fixed appliances like dishwashers and garbage disposals. It is handy because a plugged appliance can be unplugged for service, but the code sets conditions on cord length and where the receptacle sits so the arrangement stays safe and serviceable.

Common mistakes

In the field

When I set a dishwasher, I put the receptacle in the sink base cabinet next to it, not behind the unit. That way the homeowner or the next tech can unplug it to pull it for service without crawling under the counter.

Field note
I always put the dishwasher receptacle in the sink cabinet, not behind the unit. The homeowner who has to replace that dishwasher in ten years will thank me for the outlet they can actually reach.
