Junction Box Ceiling Light 70mm with WAGO 221-412 plus optional lid

Motivation
Cable outlets for lamps on the ceiling sometimes tend to be “messy”.
Connecting a lamp above your head is somewhat difficult.
Quite often connectors or clamps are missing or soiled with paint.
Heavy lamps have to be suspended with a separate hook.
Managing cables is difficult.
Unused outlets do not look very nice.

Solution
- Junction box with 3 fixed WAGO connectors.
  One channel of each connector is permanently connected to the outlet wire from building.
  The second channel is used to connect the lamp cable (easy connection and disconnection)
- The connector levers are easily accessable and have a fixed position for easier handling.
- The junction box is permanently mounted with two screws.
- A ceiling hook for heavy lamps can be integrated into the assembly.
- Cables are stored in the box so we get a neat and compact assembly.
- Unused lamp connectors can be closed with an optional lid with bajonette locking mechanism.

- Print junction box and optional lid
- Snap three WAGO connectors 221-412 firmly into their mounting positions
- Drill the holes necessary for assembly (make sure you do not damage hidden wires)
- Fixate the junction box in mounting position and fix with two screws.
- Mount the ceiling hook if required (center hole)
- Connect the wires from building (L, PE, N) to one chamber of the WAGO connectors
  (you should use the same chamber in all connectors for clear structure)
- Cleanly store away excess wire length in the junction box

- Connect the lamp wires to the corresponding WAGO connectors.
- Hang the lamp cable onto the ceiling hook
- Close the lamp cover

- In case the wire outlet is not used, you can close the junction box with the optional lid.
  The lid is fixe with a bayonette locking mechanism.
