TROUBLESHOOTING
Table 3.1 Electrical Characteristics and Recommended Wiring Size
NOTICE:
1. Select wire size based on the value of MCA.
2. MOP is used to select the fuse, circuit breaker, or a Ground Fault Circuit Interrupter (GFCI).
3. Communication cabling shall be a minimum of AWG18 (0.82mm
2
), 2-Conductor, Stranded Copper. Shielded
cable must be considered for applications and routing in areas of high EMI and other sources of potentially
excessive electrical noise to reduce the potential for communication errors. When shielded cabling is applied,
proper bonding and termination of the cable shield is required as per Johnson Controls guidelines. Plenum and
riser ratings for communication cables must be considered per application and local code requirements.
