Verified 2026-11-02 Confidence: High

Under 29 CFR 1910.269, a protective ground goes on ground end first: the employee attaches the ground-end connection and then attaches the other end with a live-line tool, and a ground comes off in the reverse order, the grounding device taken off the line or equipment with a live-line tool before the ground-end connection is removed. For lines or equipment operating at or below the voltage given in the datum value the employer may permit insulating equipment other than a live-line tool, where the line or equipment is not energized at the time or the employer can demonstrate that each employee is protected from the hazards that would develop if it were. The duties are stated in paragraphs (n)(6)(i) and (n)(6)(ii).

    6.7.1 Ground-End Clamps

    "Ground-end clamps of ground cable assemblies shall always be applied first. Clamp jaws and their point of attachment to a ground electrode (ground mat conductor, equipment ground bus, tower steel, etc.) should be wire brushed immediately before installation. The clamp must be tightened securely to provide a low resistance electrical bond and a secure mechanical connection."

The circuit or working end clamps shall always be connected and disconnected by means of hot sticks of adequate length to meet minimum approach distances given in Table 1 (Section 3), with the following exception: it is recognized that limiting dimensions in plant equipment often prohibit the use of hot sticks when attaching ground clamps to bus. [...] Remember, the bus is considered energized from a safety standpoint until properly grounded."

    6.7.6 Removal

    "Protective grounds should be removed in reverse order from installation. The circuit-end clamps should be disconnected in succession, starting first with the farthest ground cable or circuit, in a manner that creates a safe exposure (minimum approach distance) to ungrounded circuit conductors as the grounds are removed. Ground-end clamps must be disconnected after the circuit-end clamps have been removed. Account for all protective grounds to ensure they have been removed before re-energizing the line or equipment."
