Critical Components Information Components having special characteristics are marked s and must be replaced with parts having specifications equal to those originally installed. 2. Leakage Current Measurement (For 120V Models Only) When service has been completed, it is imperative to verify that all exposed conductive surfaces are properly insulated from supply circuits. G Meter impedance should be equivalent to 1500 ohms shunted by 0.15µF. WALL OUTLET EQUIPMENT UNDER TEST AC LEAKAGE TESTER OR EQUIVALENT INSULATING TABLE G Leakage current must not exceed 0.5mA. G Be sure to test for leakage with the AC plug in both polarities. For U model “CAUTION” “F501: FOR CONTINUED PROTECTION AGAINST RISK OF FIRE, REPLACE ONLY WITH SAME TYPE 5A, 125V FUSE.” For C model CAUTION F501: REPLACE WITH SAME TYPE 5A, 125V FUSE.
