Simple question regarding breaker amperage

Hi, I have a sub panel going to a well in my yard. The breaker at the main panel on the house supplying the sub panel is a 2 pole 240V that is labeled "100" on each side of the breaker switch. Do I add these numbers together for each hot leg for an amperage of 200 amps or is the breaker a 100 amp breaker?

You have 100 amps at 240 volts. Specifically you have 100 amps through each 120 volt leg of the 240 volts, but that means 100 amps at 240 volts.

You could run two hundred 1-amp 120-volt light bulbs, but you could not run one 200-amp 120-volt light bulb (if such a thing even existed).

It's like one woman can have a baby in nine months, but nine women cannot have a baby in one month.

LOL Now THAT is a great analogy!

BTW: One woman, my wife, just had a baby Friday. I was wondering how I would manage to let you guys know about our new addition without posting an off topic thread.

You could, of course, run two 100-amp 120-volt light bulbs. (Sorry, had to post something on topic.)

Congratulations!

Or one 100-amp 240-volt bulb (just to stay on topic).
