My panel is 150A, but that's just the panel. Maybe that's all they had on the truck when they installed it twenty years ago.
Can I tell from looking at the service entry cable size if it could have been higher? I figured maybe if I looked I could tell whether it was 0 or 1/0, 2/0 etc
I think I've just answered my own question: I have Cu coming into the house (well from the meter to the house), so to upgrade to 200A, I'd need 2/0
Reference: Electrical Service Entry Wire Inspection & How to Determine Electrical Service Ampacity: How to Inspect (and I'm sorry about all the adverts)
also: Electrical wire sizes & Diameters, Wire Size Tables for Normal & Long Wire Runs (use a plastic caliper - lol)
Here's the SEC in the panel
