A polyphase power distribution and monitoring apparatus having sets of
outputs for each phase of power and monitors for each phase of power
disposed in the housing. Each monitor provides a visible display of
current for an associated phase of power and an audible alarm for each
phase of power if the current exceeds a predetermined value or falls
below a predetermined value. In three-phase wye power systems, the
apparatus preferably includes a neutral line monitor, including a neutral
line current display and audio alarm, for the neutral line of the wye
power circuit. The apparatus preferably is lightweight, elongated,
portable, and mountable to the side of an electronic equipment rack. It
may also include additional power monitoring systems such as network
power monitoring tools for remotely monitoring the apparatus.
