Choose a centralized lighting terminal block that matches the module type, such as an eight-channel dimmer, relay, 0-10V dimmer, bus power supply, or Ethernet switch, because each version provides the appropriate connections. Confirm that it mounts in the selected two-slot or five-slot panel and supports the project’s field wiring, including line, neutral, and load conductors, during rough-in and trim-out.

Centralized lighting terminal blocks accommodate line, neutral, and load field wiring for each circuit in a panelized lighting system. They support 22- to 12-AWG wiring and allow field connections during rough-in before lighting modules are installed during trim-out.

Centralized lighting terminal blocks let installers terminate line, neutral, and load wiring during the rough-in phase, before the lighting modules are installed. During trim-out, the modules can be mounted next to the terminal blocks and connected to the prepared wiring, which helps separate early wiring work from final device installation.

Match the centralized lighting terminal blocks to the panel’s available slots and the modules they will serve, such as dimmers, relays, bus power supplies, or Ethernet switches. Allow enough space for the required modules and field wiring, and select a two-slot or five-slot panel based on the planned circuit count and system layout.
