Group Motor Installations
The rules and allowances for sizing of the over current protection for
NFPA 79 motor groups is covered by 7.2.10.4, Table 7.2.10.4 and
Table 13.5.6. These rules in Tables 7.2.10.4 and 13.5.6 are intended to
limit the maximum SCPD for a group. Therefore each ArmorStart
controller with its factory-supplied output motor cable is suitable for
single-motor or multiple-motor group installations on industrial
machinery when installed according to NFPA 79, 2002. The
controller and output motor cable have been evaluated as a single
system. The maximum over current device rating or setting is limited
to the value in Table D.1 for the smallest user-supplied input line
conductor, by the controller's maximum rating, or as allowed by the
UL Certificate of Compliances 012607-E3125, E96956, and E207834
for the combined use of ArmorStart and ArmorConnect components.
The Certificate of Compliances allow the ArmorStart Distributed
Motor Controllers Models 280*-*10*, 281*-*10*, and 284*-*10*
respectively to be used with ArmorConnect input cable media 280*-
PWRM22*-M*, 280S-PWRM22*-M* Cable Assembly branch
circuit taps, and 280*-M22*-M1 ArmorConnet Panel Mounting
Fittings when the group motor branch circuits are protected with a
maximum 40 A non-time delay or a 20 A time delay, Class CC, T or F
fuse.
These ArmorStart and ArmorConnect product UL Certification of
Compliances effectively extend Table D.1 to allow ArmorConnect
branch circuit taps and mounting fittings constructed with 16 AWG
conductor sized to be connected to appropriate ArmorStart motor
controllers. See Table D.1.
