The "J" leads are usually internal thermostat leads used to shut down the motor on high winding temperature. I am not sure about the "manual momentary start" comment. I think they are looking for a motor starter with a three wire start stop circuit. The "J" leads would be connected to the control circuit to drop the starter out on high temperature. The word "manual" in that comment does not make a lot of sense to me.
The code only applies to T&M work....it does not apply to contract work.
