24 VAC Wiring & Power Specifications
Follow all National and Local Building Codes when installing clocks.
24 VAC Wiring Requirements
All clocks should be connected to a single power source. If multiple power sources are needed to accommodate the load of the
clocks, all of the power sources should have the same rating and be installed on separate branch circuits. Never install different
size power sources on the same branch circuit.
For installations where 24 VAC wiring exists: gauge/length of the wire and rating for the supply transformer should be verified
l
to ensure adequate current supply and voltage for all connected devices.
For new installations: supply wire gauge should be determined to ensure acceptable voltage drop based on installed length
l
from the supply transformer to most distant clock to ensure minimum voltage (18 VAC) is assured.
Use two wire nuts, sized appropriately for the gauge of wire, to secure building supply wires to wires extending from clock power
supply.
