Typical costs for grounding an electrical panel depend on soil conditions, panel size, location, and whether a licensed electrician is required. The main cost drivers are labor time, ground rod or grounding conductor length, permits, and any trenching or concrete work needed. Grounding is something that must always be done by a professional electrician. It offers high levels of safety and quick fault response. When lightning strikes or a rogue voltage surge decides to crash the party, proper grounding steps in like a seasoned bouncer, redirecting danger away from. This report describes Phase I of a two-phase project to assess industry practices and standards for grounding and bonding of medium-voltage underground residential distribution (URD) and underground commercial distribution (UCD) circuits and worker safety in worksites with these systems.
