The switchboards described in this manual are the dead-
front type as defined in NFPA70 (NEC), UL891 and NEMA
PB2. All parts, conductors, and insulation materials are
designed and constructed to suit the voltage class of
the equipment and are enclosed within grounded metal
enclosures.

enclosures.
The equipment furnished has been designed to operate in a
system having the circuit capacity specified by the purchaser.
If, for any reason, the equipment is later used in a different
system, or if the short-circuit capacity of the system is
increased, the momentary rating of the switchboards, the
interrupting capacity of the protective devices and the bus
capacity must be checked. Should the service be changed,
the equipment must be checked to assure that the short
circuit capacity, amperage and voltage class of the equip-
ment meets or exceeds the requirement of the new system.

Switchboards are free-standing units rated 6000 amperes or
less at 600 volts AC or less. A typical switchboard will contain
the service entrance section with main devices and distribution
sections with branch devices. The sections contain disconnect
devices, protective devices, auxiliary equipment, and any current
less at 600 volts AC or less. A typical switchboard will contain
