JHBB switchboards provide a convenient and economical means of distributing electric power. These enclosed, free-standing structures contain circuit breaker or fusible overcurrent protection for services rated up to 5000 A with a maximum the voltage of 1000 Vac.
An auxiliary section is also available for cable or bus transition or to provide additional space for connecting the service conductors to the line side of the main. The auxiliary section is a full-height section with a depth to match that of the adjacent section. It can contain customer metering or through the bus and incoming lug pads.
JHBB frame allows various special components to be mounted in the switchboard. These components include automatic throw over systems, transfer switches, and special metering systems. This flexibility means the JHBB switchboard can meet customer requirements on the most complicated applications.
