Moving Sprinkler Controller: Splicing 18 AWG Wire with Standard Connectors

Extending Controller Wires from Basement to Garage

7-strand Baron 18 AWG wire needs lengthening. Can splice with Rain Bird wire?

Yes—Any 18 AWG Wire Works

• Indoor splices: standard wire nuts.
• If exposed to sun/buried: UF-rated (direct burial) wire—all "irrigation wire" is UF-rated.
• Rain Bird wire is fine.

Best Practice

1. Install small junction box in basement at splice point. 2. Make all connections inside box. 3. Label each wire (masking tape + marker). 4. Run extended wire to garage, mount controller.

Safety Note

24 VAC feels like a bee sting. Box protects wires and people.
