FAQs
Installers should note the unit supports #14-#2 AWG conductors and features a grounded with isolated return configuration. Mount the enclosure in a weatherproof, outdoor-rated location, ensure the NEMA 4X sealing is intact, and connect to the DC PV string per the UL 1741/NEC 690 requirements. No fusing is included, so plan protection upstream accordingly.
The DCG1101UXM is rated for 30 A and up to 1000 VDC, configured as a single non-fusible disconnect. This provides a straightforward isolation point for DC PV circuits, while upstream fusing or overcurrent protection remains the responsibility of the overall system design. The non-fusible design simplifies compliance and reduces component counts in appropriate applications.
Yes. The enclosure is NEMA 4X rated and constructed from 316 stainless steel, delivering superior corrosion resistance and weather sealing. This makes it well suited for outdoor solar installations, coastal or industrial environments, and other harsh conditions where durability and reliability are critical for uptime.
The unit features NEC 690 compliance under UL 1741 and UL 98B certifications, reinforcing suitability for solar DC protection installations. These certifications help ensure code compliance, interoperability with other PV components, and documented safety performance, which simplifies procurement and reduces regulatory risk for projects.
Maintenance is typically low due to the rugged 316 stainless steel NEMA 4X enclosure and solid-state grounding design. The investment pays back through reduced downtime, fewer field faults, and longer service life in outdoor PV deployments. The unit also aligns with Eaton’s warranty policy, supporting predictable lifecycle costs and service planning.
