Which option is a requirement for bonding on a fire sprinkler system?

For a fire sprinkler system, bonding is crucial for ensuring safety and compliance with electrical codes. The requirement for bonding to the electrical service is vital because it helps establish a reference ground that can enhance the system's performance and minimize the risk of electrical shock or equipment failure.

When the fire sprinkler system is bonded to the electrical service, it reduces the potential difference between metal components of the system and the grounding system of the electrical installation. This is particularly important in the event of a fault, as it helps ensure that any stray electrical currents are safely redirected to ground, reducing the risk of shock to personnel and improving the overall safety of the system.

In summary, bonding the fire sprinkler system to the electrical service is a standard safety practice that ensures proper grounding and enhances system safety, making it an essential requirement in fire protection design.
