FAQs
For outdoor solar PV applications, mount the DCG3104UPM in a weather-protected location with the NEMA 4 rated enclosure facing the anticipated ingress exposure. Ensure proper clearance for 35.38 in length, 24.26 in width, and 11.63 in height, and plan for the 80 lb unit weight. Use appropriate wiring from LC SR and EG main lug configurations (up to 300 kcmil-#6 for LC/SR and #4-#14 AWG to 1/0-#14 for EG) to meet the 200 A rating and three circuit capability. Verify grounding continuity and confirm 1000 VDC system voltage is within the device rating during commissioning.
The DCG3104UPM is certified to UL 98B and NEC 690 per UL 1741, reflecting compliance with recognized safety and electrical codes for DC power conversion systems. Its non-fusible, grounded design supports safe operation and straightforward maintenance while meeting the stringent protective device standards required for photovoltaic installations. This alignment reduces regulatory risk and facilitates project approvals for solar arrays, battery storage, and other 1000 VDC configurations.
Yes. The product specifications include LC main lug capacity up to 300 kcmil-#6, SR in 300 kcmil-#6, and EG in #4-#14 AWG to 1/0-#14. With a 200 A rating and three circuits, the DCG3104UPM supports multiple solar strings and complex DC distribution schemes while maintaining a compact footprint. Always verify field wiring practices and torque requirements per installation guidelines.
