I was working on a pole light today and opened up the cover to change the lamp and got shocked with 480V! After I turned the power off I inspected the light and found no visible places in the wire insulation and nothing was loose. The only thing I found was that the bolt that bonded the ground was rusted and had come loose. So how did I get shocked through the lamp? Is there some kind of insulation inside the lamp that could have been defective?
