FAQs
The DCG1101UWM is designed for outdoor solar PV installations with a single 30A circuit and grounded, isolated return. It supports conductor sizes #14-#2 AWG for both lug connections and solid returns, aiding compatibility with common PV harnesses and combiner boxes. Ensure the system voltage does not exceed 1000 VDC and reference the product dimension tables for configuration options. Proper clearance and weather exposure should be maintained to preserve the NEMA 4X enclosure integrity over time.
Key specs include a 30A amperage rating, 1 circuit, grounded, and non-fusible protection, with a 1000 VDC system voltage and voltage rating. The enclosure is NEMA 4X made from 304 stainless steel, suitable for outdoor use. It is designed for DC photovoltaic applications with isolated return, aligning with UL 98B and NEC 690 per UL 1741, ensuring safety during switching and maintenance.
Yes. The NEMA 4X enclosure and 304 stainless steel construction provide robust outdoor protection against weather and corrosion, making it suitable for industrial and commercial solar installations. Its DC ratings and isolated return design support safe operation in distributed PV systems, while the 1000 VDC capability matches many utility-scale and rooftop array configurations.
The unit is UL 98B certified and complies with NEC 690 per UL 1741, ensuring PV system safety and electrical protection standards.
