The difference in price of all the fittings, weather heads, SE connectors, bugs,meter pans

Well, like Doug said, it's only a few dollars difference on the equipment.

That was a very simplistic consideration of what might be involved.

error:

11888/240 = 49.5 amperes in place of 99 amperes. Also, I should have added 5000 VA for the hot water heater. 17720+5000 = 22720 VA 8000 + 0.4(2272-8000) = 13888 13888/240 = 57.9 amperes

This is a beautiful illustration. keep in mind that these figures include an electric range and dryer that may not exist.

You can ask for a service calc. This will take in square footage, and electric usage from major appliances.

Now the knee jerk reaction is to get the 'biggest' but the trend is toward more energy efficient applicances, and with a limited square footage, it might be most cost effective to get what you need.

Just thinking out loud....

Nate is that garage attached or detached. IOW is it part of the house or a separate free standing building. Tom Horne

Well we aren't no th> I'm digressing a bit, but sort of on the same topic, I have a question

regarding the wiring between my house and my garage. The house's breaker panel has a 100A 2-pole breaker in it, which feeds the subpanel in the garage. The other end of that wire connects to a 100A 2-pole breaker in the sub-panel. That just seems weird and redundant to me. Is this common practice, and what is the reason for it? Or did someone improvise "on the fly" and what would be the right way to do it?

Nate The breaker in the garage panel should be anchored into the panel by using a main breaker kit. That breaker is serving as the code required Building Disconnecting Means.

Depending on the state and the locality you may be required to have a larger service than the national minimum. Some of the counties I work in require a 150 ampere minimum service to detached dwellings. It is worth your time to check with the local electrical inspectors office.
