FAQs
For solar PV installations, plan for outdoor mounting in a protected outdoor location with proper clearance. The four-pole, non-fusible design requires correct four-conductor routing and isolated return wiring. Verify conductor sizing up to 300 kcmil-#6 and ensure the enclosure is securely fastened to withstand environmental conditions while maintaining accessibility for service.
The four-pole arrangement provides complete isolation of all DC paths, while non-fusible protection reduces nuisance fuse replacements and simplifies diagnostics. Grounded operation and isolated return improve fault clarity, enabling safer de-energization during maintenance and faster troubleshooting in PV arrays.
Yes. It supports In/Out LC up to 300 kcmil-#6 and In/Out SR up to 300 kcmil-#6, enabling direct connections to commonly used PV conductors. This reduces the need for additional lugs or adapters and streamlines installation in dense PV layouts.
The device is certified UL 98B and NEC 690 per UL 1741, with a NEMA 4X enclosure suitable for outdoor environments. These standards help ensure electrical safety, compliance with solar installation codes, and reliability in harsh weather conditions.
The DCG4064UWM reduces maintenance risk with a rugged outdoor-rated enclosure and robust isolation, potentially lowering downtime and service costs. Its large conductor support simplifies wiring, while UL/NEC compliance minimizes inspection delays, contributing to faster project payoff and lower lifecycle costs.
