A used chest freezer is a plug-in cabinet whose refrigerant circuit was completed and sealed at the plant, and its data plate gives the charge as eighty-eight ounces. Where does that number place the unit for certification and recovery purposes?
Correct Answer
B) Outside the small appliance category, because eighty-eight ounces is over five pounds
Five pounds is eighty ounces, so a charge of eighty-eight ounces is five and a half pounds and sits above the boundary. That single fact takes the unit out of the small appliance category no matter how it was built, so a Type I certification does not cover opening its circuit and the small appliance recovery levels do not govern it. Manufacturers state charges in whichever unit suits the size of the system, and reading a charge in ounces as automatically small is the mistake this data plate is set up to catch.
Why This Is the Correct Answer
The small appliance limit is five pounds, which is eighty ounces. Eighty-eight ounces is five and a half pounds, above the line, so the unit fails the charge test even though it passes the factory assembled, factory charged and hermetically sealed tests. Failing any one of the tests puts the appliance outside the category, and this one fails on charge alone.
Why the Other Options Are Wrong
Option A: Inside the small appliance category, because eighty-eight ounces is under five pounds
Eighty ounces is exactly five pounds, so eighty-eight ounces is half a pound over the limit rather than under it.
Option C: Inside the small appliance category, since a charge given in ounces is a small charge
The unit a charge is written in tells you nothing about its size. Plenty of manufacturers list charges of several pounds in ounces because that is how the factory measures them.
Option D: Outside the small appliance category, because a chest freezer is commercial equipment
Where an appliance is used has never affected its classification. A commercial setting does not remove a unit from the small appliance category, and a household setting does not put it there.
Memory Technique
Eighty ounces is the fence. Eighty-eight is on the far side of it.
Reference Hint
Small appliance limit is five pounds, which is eighty ounces or about 2.27 kilograms.
