A CAT IV rating means the meter is built to survive the voltage spikes found at the origin of an installation: the service entrance, the meter base and overhead or underground feeders. CAT IV 600 V is the usual choice for electricians working on services; CAT IV 300 V covers services up to 300 V to ground.
