Abstract
A self-cleaning hot line clamping device used by electric utilities, having clamps for electrically connecting a line conductor to another piece of electrical equipment such as a second line conductor or tap conductor. At least one of the clamps has a first jaw in the form of a V-shaped recess, and a second jaw to force a line conductor into the recess in wedging contact with the converging surfaces of the recess. The converging surfaces of the recess are serrated to have a wiping action on the line conductor at the contact points so that when the line conductor is forced into the recess surface oxide on the line conductor at the contact points will be removed.
