Follow all National and Local Building Codes when installing clocks.
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 to ensure adequate current supply and voltage for all connected devices.
For new installations: supply wire gauge should be determined to ensure an acceptable voltage drop based on installed length from the supply transformer to the 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 the clock power supply.

**With all segments on, test only.
Note
Peek start current (in-rush) could be as much as three times stated values.
