I'm setting up a temporary power pole, but I can't find an answer to this question: I only need 100 amp service, but finding a 100 amp meter base isn't very easy. Can I install a 200 amp meter base, then have my main breaker at 100 amp? From what I understand, the meter base can be higher amp than your main breaker, just not the other way around.
The 200 A capacity of the meter base and/or panel is the max capacity of that panel. If you put a 100 A breaker to protect it, that will be fine. You only create a safety concern if you put a breaker that has a GREATER capacity than the equipment it's going into.
For example you would NOT put a 200 A breaker in a 100 A panel.
