LAB 4 : ESB AND AMF CABLE SCHEDULE

PURPOSE OF CONTINUITY TEST

Continuity test means – it will ensure that a circuit is complete. The continuity test is simple, and it involves sending a small voltage through the desired direction. The flow should go through that path to confirm the circuit is complete. But if there’s too much resistance, it means there’s a problem. It could be component damage or a broken conductor, but it indicates an “open” circuit. That’s a problem you should deal with as soon as possible. Continuity tests serve to discover them on time and avoid further issues.

PANEL TYPE

ESSENTIAL SWITCH BOARD (ESB)

AUTOMATIC MAIN FAILURE (AMF)

FUNCTION ESB and AMF

ESB function

The TNB supply is connected to the ESB panel and signals the AMF when the main power fails. For example, if there is any supply interruption in a certain place, the ESB will send a signal to the AMF and make an automatic electricity transfer for the building's load from the mains to the standby generator.

AMF Function

AMF and ATS panels monitor the incoming AC mains supply, activate the standby generator when mains power fails, and make an automatic electrical transfer of the building’s load from the mains to the generating set. When the mains supply returns, the AMF panel controls a return to the mains supply and shuts down the generator after a suitable cooling run.
