3. A short section of the main feeder wires will need to be replaced as they come into the new MCC and Panels.

The DC Contactors will be located on the wall in a panel beside the AC or inside the cutout in a separate box above an off-the-shelf 120V AC panel. The other 10 of 16 are 120/240 AC only panels. The ampacity of the lighting panels has been reduced due to lower loads. See specifications for the details and ampacity of each panel.
