The front panel power switch is also
a circuit breaker. As a circuit breaker,
it prevents excessive current from
entering the PIU.
When the power is on, the Switch is
illuminated. When the breaker trips,
the
switch
returns
to
its
“off”
position.

Per CSA code, devices with line
cords and plugs must not consume
more than 80% of a branch
circuit’s rating.
While Torus Power Isolation Units
are designed to handle well beyond
these limits, they must be marked
with a maximum input current that
satisfies the requirements.
