• Adhere to the CAT II 500V and CAT III 300V safety ratings. CAT III is for measurements in building installation (e.g., distribution boards, circuit breakers, wiring, including cables, bus-bars, junction boxes, switches, socket-outlets in the fixed installation, and equipment for industrial use and some other equipment, e.g., stationary motors with permanent connection to the fixed installation). CAT II is for measurements performed on circuits directly connected to the low-voltage installation (e.g., household appliances, portable tools).
