Typical Applications
CAT II
Single phase receptacles - Household appliances, power tools
and connected loads - Outlets more than 30ft (10m) from a CAT III source
- Outlets more than 60ft (20m) from a CAT IV source
CAT III

CAT IV
Connection point to

utility power and outdoor - Overhead or underground lines to detached buildings
conductors
- Incoming service entrance from utility
- Outdoor pumps
The measurement category (CAT) rating and voltage rating is determined by a combination of the meter, test probes
and any accessories connected to the meter and test probes. The combination rating is the LOWEST of any individual
