Distribution Section switchgear, switchboard power panelboard section that
receives power from the service section and distributes power
to other circuits.12
Discrete I/O Inputs (I) and outputs (O) that are either off. Duty cycle
is normally expressed percentage; therefore, device with
a 50% duty cycle half the time.
