What are the orange clamp connectors in RV ceiling wires?

In the photo, you can see two groups of ceiling wires hanging down through the opening where a rooftop air conditioner is being replaced. The clear plastic pieces with orange clamps are Wago 221 lever connectors. These are reusable electrical connectors that hold stripped wires securely in place without twisting them together.

Wago connectors are common in RVs because they make it easy for technicians to disconnect the old AC unit and reconnect the new one. You flip the orange lever up, insert the stripped wire, and close the lever to lock it. This keeps the copper protected and prevents the wires from touching metal framing or each other while the AC is removed.

In a setup like the one shown in the image, the wire bundles typically include:

• 120V power wiring (black hot, white neutral, green ground)

• Control or thermostat wiring that the new AC unit will reconnect to

When the new rooftop air conditioner is installed, the technician simply reconnects the unit’s wiring harness to these ceiling wires, often using the same Wago connectors or a fresh set. Seeing dangling wires at this stage of the install is normal, and the connectors are there to keep everything safe and organized until the new unit is secured.
