Air Conditioner Lightning Protection

Spotted outside a second-floor window:

Each air conditioning unit has a pair of lightning rods atop it, with their aluminum grounding cables securely clamped to the steel frame underneath.

The rod reclining on its side caught my eye. Perhaps its fat cable wasn’t relaxed enough during installation, although I thought those wide bases would be firmly screwed to the unit’s steel top. Of course, that could be the only one without screws.

The building extends another three stories upward from that roof, but our experience suggests lightning strikes where it will.
