I have recently put up a steel building for a horse barn, steel framework, steel siding, and sitting on 4"stone dust and 2ft of shale, to the West Virginia clay. The building is secured to the ground using six 4’ steel screw anchors (mobile home anchors) bolted to the metal frame and 6 4’ steel pins (looks like rebar fashioned into a common nail) hammered through the steel floor plates.
Near to where the barn sits is a 240v trailer connection (2 separate outlets-not used, belond to previous property owners) into the house panel which I plan on extending to a small load center in the barn. From that I plan on installing 6 lights (1 circuit) and 6 fan outlets (2 circuits).
Is this building sufficiently grounded and bonded, or do I need to install one (or more) copper rods to have an electrically safe building. If so, how long does it (they) need to be? Since the ground wire runs to the house panel, do I need to do anything additional to protect the house circuits? Does any of the above meet the requirement for lightning protection…fried horses don’t ride well.
Is there anything else I didn’t think of to ask or that I should do?
Thank you for your input
