When determining if a light fixture must be bonded to the LPS, which condition is relevant?

The determination of whether a light fixture must be bonded to the Lightning Protection System (LPS) is critical for ensuring safety and effectiveness in protecting facilities from lightning strikes. Condition 2a specifically addresses the criteria for bonding fixtures to the LPS. This condition typically involves the following key elements: evaluating the type of fixture, its potential for carrying lightning current, and the installation's compliance with safety standards.

Condition 2a is significant because it ensures that any light fixture that may become energized during a lightning event is adequately protected through bonding. This involves connecting it to the grounding system of the LPS, which helps to dissipate any lightning-induced surges effectively, minimizing the risk of damage to the fixture and reducing the chance of injury to personnel.

In contrast, other conditions address different aspects of bonding and safety, but they do not provide the specific criteria relevant to determining the necessity of bonding light fixtures in the context of lightning protection. Thus, Condition 2a is the appropriate choice as it directly relates to the safety requirements and considerations for bonding light fixtures to the LPS.
