The following classifications and limitations of panelboards have
been established by the Underwriters Laboratories and the
National Electrical Code. Note— “an overcurrent protective device
is a circuit breaker pole or single fuse”. Panelboards have no fire
wall ratings. All 50/60 Hz rated. There is no limitation as to the
number and rating of branch circuits, except as determined by
available enclosures.
Interrupting Ratings—Circuit Breakers
Panelboards have integrated short circuit ratings. When fully
rated, the rating is that of the lowest rated device in the panelboard. When series connected rated, the rating is that of the
main device in panel (or remote line side protected device) and
branch-tested/UL Listed combination.
Short-Circuit Ratings—Fusible Switch Units
The interrupting rating of the fuse must equal or exceed the
short-circuit rating of the switch. If it is lower, then the interrupting rating of the switch is the same as the fuse. Switches have no
short-circuit rating if renewable fuses are used.
Seismic Ratings
All A-Series™ II Lighting Panels and Spectra™ Power Panels have
been tested and certified to meet the International Building Code
(IBC) Zone 3 and Zone 4 as well as the California Building Code
(CBC) Zone 4.
