I keep wondering how it can be that I'm powering all my basement gear through a 15A circuit and have not managed to trip it. Voltage is rock stiff too.

Depends on temp conditions and age of breaker. In commercial, we can sneak out a longer time curve for compressors or large motors with a breaker with a 22KA interrupting rating vs 10KA with same overcurrent setting.

Page 32 onwards explains inverse time curve. Higher the current, shorter the trip time.
