Motor overload protection for domestic appliances

THE REQUIREMENTS of Underwriters' Laboratories, Inc., for the protection of motors in domestic appliances are based primarily on the rules for protection of motors as given in the National Electrical Code. The requirements of the National Electrical Code, however, must be a type that can be administered by inspection authorities in the field, and therefore do not contemplate the evaluation of a specific motor application to the same degree that can be accomplished readily in a testing laboratory.
