Light Archon Bulwark 125A Main Lug Load Center

Light Archon Bulwark main lug load centers handle subpanel and small-feed distribution at 125 A, from a compact 4-space outdoor box to a 20-space indoor panel with factory ground bar. All units are quote-first; the trade desk confirms the configuration and the feeder plan before release.

The aluminum bus is rated 125 A with a 10 kA interrupt rating on the verified indoor unit. Indoor units are NEMA 1; outdoor units carry a NEMA 3R cover. The 8-space indoor unit has a flush door with a drywall depth mark on the enclosure and a single keyhole mount at the top for fast leveling, plus a center knockout for conduit entry. A rigid one-piece plastic backpan seats the branch breakers solidly, and the 12-space contractor kit ships with two 20 A single-pole breakers to start the schedule.
