When bonding and grounding electrical components to a fire sprinkler system, which practice is not allowed?

Grounding is not allowed when bonding and grounding electrical components to a fire sprinkler system because grounding would create an undesirable path for electrical current that could potentially cause issues within the sprinkler system. Fire sprinkler systems are designed to operate independently and serve a specific purpose of fire suppression, and introducing grounding connections can compromise their integrity and performance.

In contrast, bonding is a critical practice that ensures electrical continuity and safety by connecting various metal components together to eliminate potential voltage differences. Ensuring that all metallic components within the sprinkler system are properly bonded improves safety by reducing the risk of electric shock to maintenance workers and ensuring that any static electricity is safely dissipated.

While wiring and the installation of circuits are also integral components of electrical work, they are performed under strict guidelines to ensure safety and compliance with regulations. However, these practices are not directly related to the specific concern of grounding within the context of a fire sprinkler system. Thus, ensuring that grounding is not employed clarifies the distinction between electrical safety measures and the operational integrity of fire protection systems.
