Only fuses of the proper amperage for the control of the circuit are to be used. To prevent the use of improper size fuses by tenants, authorities should install fustats and adapters of the proper amperage, usually 15 amperes, in the fuse box located in apartments. Tenants should also be cautioned on use of electrical appliances so as not to overload circuit.

All electrical equipment should be kept in a state of good repair. All motors, including oil burner and heat distribution motors, should be cleaned, oiled and checked at frequent intervals as recommended by the manufacturer. Electrical equipment having heating elements should be used with care and safely placed so as not to set fire to adjoining surfaces. All electrical equipment should bear the Underwriters' Label of Approval. Frayed or worn cords on portable devices should be replaced. Extension cords should be used only to meet temporary requirements and should not be used as a substitute for permanent wiring.

Electrical equipment, such as washing machines, dryers, commercial refrigerators, ranges, etc., present a shock hazard unless grounded in an acceptable manner. Certain portable electric tools, such as drills, saws, etc., also present a shock hazard unless properly grounded, usually by means of a multi-prong plug properly connected to the electrical source.
