An insulated boom knuckle cover for high voltage line truck includes an insulating sheathing unit disposed for expedient attachment to a boom arm of a high voltage line truck. The sheathing unit includes an upper section, attachable to the boom arm at a position proximal a knuckle of the boom arm, and an arched knuckle cover section disposed depending from the upper section. The arched knuckle cover section includes a lowermost portion disposed to overlie the knuckle of the boom arm when the boom arm is disposed in a lowered, folded position, and yet maintain appropriate coverage of the knuckle when the boom arm is also extended away from the lowered, folded position. The present invention therefore prevents direct contact of high voltage lines with the knuckle, or portions of the boom arm proximal the knuckle, and shields the knuckle from arcing.
