2.6.2 Low-Voltage Control Wire Sizing
Low-voltage wiring should be sized to allow a 1 volt maximum drop due to line resistance between the
evaporator and condensing unit. Use NEC Class 1 or 2 wiring according to wire routing conditions
chosen, local codes and application limits in
Tables 14
and
15
.
