Dan that "peak" hp figure will not trip a 20 amp breaker because the breaker is setup to handle sharp quick loads. It may very well draw over 20 amps very briefly, but if it continues past a few milliseconds the breaker will take it out. In industry in large motors we use what is called a slow blow fuse that rides through the inrush current a motor draws when starting.

FWIW, that "peak" HP figure is absolutely meaningless when trying to figure out a motors capacity.
