Arc faults result from worn damaged
insulation and are common cause fires.The
unit for apparent power the volt-ampere, abbreviated “VA. Apparent
power calculated multiplying current times voltage.

Arc Chute Assembly assembly metal plates surrounding circuit breaker or
contactor contacts. Arc chutes are used reduce contact
damage quickly extinguishing the arc created when contacts
open.

Arc Fault electrical arc which causes current flow unintended
ways, but often not sufficient amounts cause standard
circuit breaker trip.
Analog Output output from system that can continuously vary over a
range current voltage such milliamps 10
