In our experience it's really impossible to actually use a constant 20 amps. We'll load in servers till we're up to around 16-17 amps - any higher and a spike of high activity could force the amps over the limit and trip the circuit breakers. The actual amps used by our servers will tend to vary - power usage seems to go up in the middle of the night when we do our backups.
