Table E.1 Extended NFPA 79, Table 7.210.4, Relationship Between
Conductor Size and Maximum Rating or Setting of Short-Circuit
Protective Devices for Power Circuits
For 16 AWG conductors the branch circuit breaker must be marked for use the 16 AWG wire, NFPA
79, 12.6.1.1.
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.
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.
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.
The Listed ArmorStart motor controllers with their factory supplied
motor cable carries the marked maximum ratings shown in the
following table.
Class J, CC, and T fuses only.
ArmorConnect power media and tees may only be used with fuses.
