The continuity of equipment grounding conductors at events such as carnivals and circuses shall be verified every time what occurs?

The verification of the continuity of equipment grounding conductors is crucial for ensuring the safety of portable electrical setups, particularly in transient environments like carnivals and circuses. When portable electrical equipment is connected, it is essential to check that the grounding system is intact and functioning properly. A reliable ground connection protects users from electric shock and helps prevent electrical hazards, especially given the variable conditions and potential for movement in such settings.

In the context of portable equipment, the grounding conductor must be continuously monitored every time equipment is connected to ensure that it maintains a path for fault current, thus facilitating the operation of overcurrent protection devices in the event of a fault. This is particularly critical since portable equipment is often set up and dismantled frequently, making it susceptible to damage or disconnection of grounding systems.

This focus on grounding during the connection of portable equipment highlights the elevated risk associated with temporary setups, emphasizing the importance of confirming that grounding integrity is maintained each time equipment is brought online.
