Wire sizes based on recommendations of the American National Standards Institute (ANSI) approved National Fire
Protection Association's (NFPA) National Electrical Code (NEC). Table 310-16 for copper wire at 90°C conductor
temperature operating in ambients of 30
°
C and 40
°
C was used. For other operating ambient temperatures, refer to the
NEC. For operation in countries where the NEC is not recognized, follow applicable codes.
2
Recommended wire sizes are sufficient to restrict voltage drop to 1.0 volt or less at listed branch current for the loop
lengths shown. Loop length is the sum of the lengths of the positive and negative leads.
3
Wire Size / Loop Length Combination Calculated using 30°C Ambient Operating Temperature.
4
Wire Size / Loop Length Combination Calculated using 40°C Ambient Operating Temperature.
