load calc for motors

[hawkeyehawley]

I know i'm going to feel like a dummy, but i need some help.
We up graded an existing 60amp 3phase service that was supplying a fountain in the retension pond in a residential community. the fountain was driven by a 3hp 3 phase motor.
We up graded the service to a 200 amp 3phase service. The inspector said all was fine but that he needed to see a load calc. I've done load calcs for homes, apts, etc. but never for motors in a situation such as this...and my boss has no clue. there are 3 motors...a 3hp, a 10hp and a 20hp...all 3phase. Please...just point me in the right direction to do the calcs.
thanks

For the purposes of performing a load calculation, just list the nameplate rating of each of the motors, increase the largest motor by 25%, and add them all up.
