Wiring Contractor Insurance — Coverage, Cost & Requirements
Wiring contractors — whether specializing in residential rough-in, commercial low-voltage systems, or data and communications cabling — face liability every time they touch a building's electrical infrastructure. Incorrect wiring can cause fires, equipment failures, or failed inspections that delay entire construction projects. Wiring contractor insurance includes general liability with completed operations to cover post-project defect claims, workers' comp for technicians handling live circuits and pulling wire through walls, commercial auto, and professional liability if you provide design or system specifications for electrical or data networks.
