Touchstone Electric completed a code-compliant underground feeder installation for Patrick Mornane in Union, SC. Dispatched from our Greenville branch in Taylors, technician Tyler Harris wrapped this project on April 23, 2026, delivering a clean, reliable path for a new 30-amp circuit.

• Service categories: Panels & Service Upgrades; Subpanel Installation

Project overview

This job called for a durable underground feeder to support a 30-amp circuit—ideal for small subpanels, detached structures, or equipment that benefits from a dedicated run. Our team completed professional trenching, placed the cable to the correct depth, and ensured the path was prepared for final terminations by the homeowner’s selected equipment.

• Trenching: Approximately 75 feet, prepared to meet the minimum 24-inch burial requirement for direct-burial cable.
• Feeder: 80 feet of 10/3 UF direct-burial cable installed for a 30A circuit.
• Equipment: Purpose-built trencher utilized to complete the excavation efficiently and neatly.

Per the defined scope, this installation did not include a breaker, posts, or any receptacle/switch/fixture installation. If you need a complete end-to-end solution, we can provide a tailored quote that includes these components and any required terminations.

Code-compliant depth and safety

For direct-burial underground feeders, a minimum 24-inch burial depth is required in most residential scenarios. This project was executed to meet that standard. When rigid metal conduit is used, certain exceptions may apply, but for UF cable direct burial in Union, SC, the 24-inch standard is the typical benchmark for safety and code compliance.

Before any digging, remember to call 811 to have utilities located. It’s free, it’s the law, and it keeps your property and our technicians safe. Touchstone Electric always encourages homeowners to complete utility locates prior to trenching so the work can proceed without delays or hazards.
