How to connect power to a ducted RV air conditioner
Connect the RV air conditioner to a dedicated circuit that meets local wiring codes. Locate the power cord inside the RV and securely connect the active, neutral, and ground wires to prevent shorts or overheating.
Electrical Connections (Ducted Systems)
In a ducted RV air conditioner system, the unit must be connected to a dedicated power circuit that can be shut off and meets all local wiring standards.
From inside the RV, locate the air conditioner’s power cord as shown in the diagram.
Connect the external power lines to the unit, making sure to match the active, neutral, and ground wires correctly. For most models, a 3-pole terminal block is used for these connections.
Tighten all screws firmly to remove any chance of loose wiring. Improper or unsecured connections can cause overheating, short circuits, or fire.
If your system is a non-ducted model, follow the non-ducted installation guide instead.
