Precision Trenching & Conduit Installation

Using state-of-the-art trenching equipment and PVC or HDPE conduit systems, Prevolt Electric installs underground raceways with exact depth, spacing, and backfill protection. Our team ensures all conduit lines are aligned, sealed, and supported according to NEC and utility standards. Every trench is inspected for safety and precision before wiring begins.

Wire Pulling, Terminations & Grounding

Once conduit installation is complete, our electricians carefully pull, terminate, and label all conductors. We use high-grade copper wiring with corrosion-resistant fittings and proper grounding techniques to protect your electrical system for decades. Whether it’s a residential service feed, commercial meter bank, or municipal power circuit, every connection is verified for voltage integrity and continuity.

Inspection, Backfill & Final Commissioning

Before any trench is backfilled, the entire system undergoes a licensed inspection to verify compliance with local and NEC codes. We then carefully backfill, compact, and restore the area to its original condition. Once approved, Prevolt Electric performs a final commissioning test to confirm your underground electrical system is safe, reliable, and ready for long-term service.
