How to determine when to use the CC2200X versus the CC2200?

The CC2200X breaker is used in metering. There is bus on the line side to bolt into the metering and lugs on the load side to wire to tenant breakers. The CC2200 breaker is for use in loadcenters with lugs on both the line and the load side.

CAUTION: Always consult a licensed electrician. Always adhere to local code requirements.
