What is checked before closing and securing the access door after the circuit breaker is closed with the lamp on?

Before closing and securing the access door after the circuit breaker is closed and the lamp is on, it is crucial to check that fault lamps are off. This step is important because the presence of fault lamps indicates a potential problem in the system that needs to be addressed before ensuring that everything is secured. If the fault lamps are not off, it could mean that there are underlying issues that could lead to system failures or safety hazards. Properly verifying that the fault lamps are off ensures that the system is operating normally and that it is safe to proceed with closing the access door.

Checking voltage levels, current draw, and transformer status are all important operational checks as well, but they come secondary after confirming that there are no fault indications. The primary concern is to ensure that there are no faults indicated by the lamps, which could compromise the safety and functionality of the system.
