Price of lightning protection and grounding installation for distribution boxes
Hiring a local electrician to install a lightning protection system costs about $35 to $50 per hour. Depending on the size and complexity of the job, you could pay as little as $100 in labor or more than $1,000 for hard-to-reach areas or time-consuming installation. Cost takes into account a single air terminal, conductor cables, ground electrodes, fasteners, and mounting hardware. Budget a 10% to 20% overage for roof repairs, wildlife removal, or surge. The study is intended to help building owners, architects, engineers, and risk consultants include more accurate cost estimates for lightning protection installation in their project planning. To prepare this study, East Coast Lightning Equipment, Inc.
