FAQs
Installation begins with verifying panel space for a 29.9 in width, 41.9 in height enclosure, followed by proper mounting on a rigid base. Connect the 480 V primary to the incoming feeder and link the 208Y/120 V secondary to downstream distribution circuits using the 104A30K wiring connection. Ensure compliance with local codes and lockout/tagout procedures before energizing. Plan for proper cooling and clearance around the NEMA 3R enclosure to preserve weather resistance and service access.
Key specs include a 30 kVA volt-ampere rating, 480 V primary voltage, 208Y/120 V secondary, 60 Hz frequency, and a three-phase configuration.
