Nearly every experienced industrial electrician has started up a motor at some point.When a motor starts, it consumes a lot of current - especially if it happens to be a large motor. The current is highest when a motor starts from 0 RPM and when it is activated by the switching of a contactor - an instant in-feed of the voltage driving the current through the coils.This
