D.1 MS-5UD-3(E) & MS-10UD-3(E) NAC Wiring
The following table lists NAC wiring requirements for the MS-5UD-3(E) & MS-10UD-3(E) FACP
which utilizes the FLPS-3 power supply.
Note: Calculations are based on Direct-Current Resistance data for uncoated copper wire, per
National Electrical Code (2005 Edition) Table 8, Conductor Properties.
D.2 MS-5UD-7(C/E) & MS-10UD-7(C/E) NAC Wiring
The following table lists NAC wiring requirements for the MS-5UD-7(C/E) & MS-10UD-7(C/E)
FACP which utilizes the FLPS-7 power supply.
Note: Calculations are based on Direct-Current Resistance data for uncoated copper wire, per
National Electrical Code (2005 Edition) Table 8, Conductor Properties.
