Meter Questions

CL200 is the class designation of the meter - Class 200. This means that the meter is intended to meter loads up to 200 amps on a continuous basis. It can meter larger loads for short periods of time.

TA30 refers to the test amps - In this case, the meter is tested and calibrated at 30 amps. Class 200 meters are always calibrated at 30 amps.

I have no idea what FM2S means.

The only significance for a home inspectors is that if you see a meter designation that's smaller than the service size, it's possible that the service was upgraded without notifying the utility. For instance, a CL100 meter (TA 15) would only be intended for a 100 amp service. If a 200 amp service is present, it might have been bootlegged in.
