Measurement categories indicate the ability of the meter to safely withstand the prospective fault energy available in the circuit being tested. The higher the circuit energy, the higher the category of tester required, so the higher the tester's category rating, the safer the meter. However, you need to have a rough idea of the prospective fault current available at the point of testing, usually expressed in kA. As a guide, typical kA levels are: CAT I for very low-energy circuits, typically battery-powered, not connected to 240 VAC; CAT II for low-energy circuits like domestic use up to 5 kA fault currents; CAT III for medium-energy circuits like industrial and commercial use up to 25 kA fault currents; and CAT IV for high-energy circuits like industrial and commercial use over 25 kA fault currents.
