Each seperate section has 40 positions in 2 banks. Each section is controlled by 2 contactors, 1 for each bank of 20 devices. As far as I know at this time, we will only be replacing individual devices, and then only about 80 out of 120. (?) We will be checking all terminations to make sure they are secure. Panel schedules are all incorrect but they declined to have us do a new panel schedule.
