Table D.1 Extended NFPA 79, Relationship Between Conductor Size and
Maximum Rating or Setting of Short-Circuit Protective Devices
for Power Circuits
➊
For 16 AWG conductors the branch circuit breaker must be marked for use the 16 AWG wire, NFPA
79, 12.6.1.1.
➋
The UL Certificate of Compliance for the ArmorStart Distributed Motor Controllers models 280*-*10*,
281*-*10*, 283*-*10*, 284*-*10*; and ArmorConnect input cable media 280*-M22*-M*, 280S-
PWRM22*-M* cable assembly branch circuit taps, and 280*-M22*-M1 ArmorConnect panel mounting
fittings allows 16 AWG conductors to be used when part of ArmorStart and ArmorConnect components.
➌
The 280*-PWRM22*-M* ArmorConnect cable assembly taps and 280*-22*-M1 panel mounted fittings
with 16 AWG conductors are suitably protected when protected in the branch circuit by a 40A non-
time delay fuse.
➍
The 280*-PWRM22*-M* ArmorConnect Cable Assembly taps and 280*-22*-M1 Panel Mounted Fittings
with 16 AWG conductors are suitably protected when protected in the branch circuit by a 20A time
delay fuse.
Branch Circuit Protection Requirements for ArmorConnect
Three-Phase Power Media
When using ArmorConnect three-phase power media, fuses can be
used for the motor branch circuit protective device, for the group
motor installations. The following fuse types are recommended: Class
CC, T, or J type fuses. A 100 A circuit breaker (Allen-Bradley140
H-Frame) can be used for the motor branch protective device, for the
group motor installations when using only the following
ArmorConnect Power Media components: 280-M35M-M1,
280-M35F-M1, 280-T35, and 280-PWRM35*-M*.
The Listed ArmorStart motor controllers with their factory supplied
motor cable carries the marked maximum ratings shown in the
following table.
