When designing and implementing an electrical distribution system protection scheme, several key considerations must be taken into account. These include:

Faults occur when insulation degrades or physical interference creates unintended electrical paths. Short Circuits (Parallel Faults)

She could trip a breaker. She was built to do it: to open and isolate, to protect machinery and lives. But as she scanned the grid map, she saw the hospital's feed routed through the same switch. The bakery's ovens would flame out and ruin the night's dough. Somewhere, a life support machine hummed with a fragile breath.

Ensuring the system operates correctly when required (dependability) and does not operate unnecessarily (security). 2. Core Hardware Components
