CIRCUITS REQUIRED. PROVIDE THE NUMBER OF CONDUCTORS

NEEDED TO COMPLETE INSTALLATION OF SPECIFIC EQUIPMENT

FURNISHED. A GREEN GROUND CONDUCTOR, SIZED PER NEC,

SHALL ALSO BE INCLUDED IN EACH CIRCUIT. ADJUST

CONDUCTOR SIZES AS NEEDED TO LIMIT VOLTAGE DROP TO

LEVELS RECOMMENDED BY NEC. COORDINATE INSPECTIONS

WITH THE OWNER AND AHJ.
