With a motor and the driven equipment in the space being cooled, ASHRAE estimates 87,500 Btu/hr per 30 hp motor running non-stop. You have two motors in there and they will be cycling on and off. The elevator shop drawings give a typical heat dissipation. A gut feeling or a guess, with 2@30 hp motors, 6 tons.
you don't say what type of elevator this is, but I will assume that it is a skeleton elevator with two 8' sections and a 4'section. I have a 24' skeleton made by NH in the dark ages. was too heavy to move myself so I took 8 feet off and it is still hanging in the shed 6 years later. I run it with an emerson farm duty 1.5 hp motor 110v. Plenty ...
With that being said can the elevator controller and motor be treated as the same device for sizing the feeder to the motor? Since the elevator motor is an intermittnet duty motor table 430.22(E) indicates that the feeder between the panel and the elevator controller needs to be rated for at least 140% of the elevator nameplate current.

The recommended number of people that can be in an elevator is called normal loading. Even though it is referred to as normal, most people see this as a crowded elevator and will wait for the next elevator if the traffic is heavy. The recommended goal is for the elevator to be able to move 10-12% of building's population in five minutes.

This is two separate issues for motor loads, conductor size and Short circuit protection. You must remember that "Overload protection" for the motor and the conductors is from the motor overloads and not the breaker, much different from "normal" feeders. For the conductor rating go to 2002 NEC 620.13(A) sends you to 430.22(A) and (E)
Elevator motor is 40 HP, 208 Volt/3-phase. Motor FLA from NEC Table is 114 Amps. Breaker sizing: 114 FLA x 2.5 = 285 Amps, round up to 300 Amp. Circuit Breaker #1 is in the Main Dist Panel "MDP". CB #1 is a 300 Amp thermal magnetic breaker, as follows: Siemens JD Frame, model number JXD63B300. CB #2 is inside the elevator machine room.
See attached pictures of data from elevator shop drawings, motor table shows 60R (drive HP) - 20A running amp., AC Motor Parameter Set Up table shows 60R equals 60HP. If going with 60HP, per NEC table, motor FLA = 77A. Should I size breaker to protect this elevator based on 60R or 60HP - full...
