An electrically grounded land surface mounting for an electrical fixture such as an airport runway approach light is disclosed. A flanged member connects a frangible coupling to a long, straight steel rod driven into the ground at the site. The coupling accepts a post supporting the light and can be broken if an aircraft wing or tire should strike it. The flanged member is adjustably clamped onto a first end of the rod extending above the surface of the ground at the site, and the remainder of the rod is buried in the ground at the site to discharge any electrical charge in the fixture or in the atmosphere around the fixture in accordance with the National Electrical Code or other grounding requirements.
