T7350 COMMERCIAL PROGRAMMABLE THERMOSTAT

General Considerations
Table 8 lists wiring types, sizes and distances for the T7350
and Excel 10 products. The T7350 terminal strip accepts 18
through 22 AWG (0.82 to 0.34 sq. mm) wire.
Table 8. Field Wiring Reference.
NOTE: 1. The X, RH and RC terminals will accept 14 to 22 AWG. 14 and 16 AWG should be avoided since the stiff cable
interferes with the cover to subbase installation.
