Can arrestors be put on an energized line by hand?

Arrestors are protective devices tied into high-voltage lines to clamp surges and protect equipment. Working on an energized line by hand puts you in direct contact with live conductors and possible arc flash, which can cause severe injury or death in an instant. PPE alone cannot eliminate that risk, and the safer, standard practice is to de-energize and lock out the circuit, verify zero energy, and perform the installation with the line safely de-energized (using proper tools and procedures). Because of the high risk, you never install or manipulate arrestors on a live line by hand.
