Table 7.1 Electrical Characteristics and Recommended Wiring Size
(2) Electrical Characteristics
Note the following when selecting wiring:
● Use the charts below to select appropriate sized breakers / fuses / overcurrent protection switches and
wiring in accordance with local codes.
● Ensure communication cable is 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 cable is applied, secure properly and terminate cable shield as required per Johnson Controls
guidelines. Plenum and riser ratings for communication cables must be considered per application and
local code requirements.
