Total service amps?

How many amps of service do they have? No other mains, cl200 meter and this main is rated at 125.

100 amp. And your did report the double tap??

I made a note of the double tap and told the HO while there. Thanks Bill

That one backfed breaker with the red colored hold down device appears to be used as the main in your photograph. That seems to have a 100 amp rating, so that’s a 100 amp service (unless there’s anything else more restrictive that’s not pictured).
