Trent Tarter 5 Posted August 24, 2017 Report Share Posted August 24, 2017 I found this device connected to an exterior switch. It's been abandoned as the wire is cut below it. Just wondering what could be? Quote Link to post Share on other sites
Bill Kibbel 82 Posted August 25, 2017 Report Share Posted August 25, 2017 Never seen it. Guess 1. A lightning arrester. The second wire slowly discharges to a ground spike. Guess 2. A transformer for an in-ground mole or gopher zapper. Quote Link to post Share on other sites
mjr6550 5 Posted August 26, 2017 Report Share Posted August 26, 2017 Also never saw one. Maybe a transformer for low voltage lighting. Quote Link to post Share on other sites
Rob Amaral 7 Posted August 29, 2017 Report Share Posted August 29, 2017 Sure looks like a lightning arrestor... Quote Link to post Share on other sites
