Fault current inputs

ORIENT

What this module is for

Connect available fault current to both protection speed and energy exposure.

EXPERIMENT

Study the two-sided effect of higher fault current.

Establish a baseline fault current at a panel.
Increase the source contribution and record the new value.
Describe how a faster-operating protective device changes exposure at that same point.

CHECK

Higher available fault current can reduce incident energy when:

It never canIt pushes the protective device into a much faster operating regionThe enclosure is largerWorking distance decreases

APPLY

Explain why 'lower fault current is always safer' is an unreliable rule of thumb.
