fault level

Fault levels are crucial for ensuring electrical systems operate safely. The Wiring Rules mandate that protective devices must handle any overcurrent up to the prospective short circuit current at their installation point. Incorrectly rated equipment can be hazardous, and overrating can be unnecessarily costly....

Surge diverters protect electrical systems from transient voltage spikes, known as surges. Surges can result from lightning, power outages, or switching electrical loads. They may raise the voltage beyond what most components can handle, causing damage or failure. According to the AS/NZS3000 standard, surge...
