Wiring Enclosures

Alliance CS100 Hub Enclosure

Landscape lighting has its own version of a “valve box” problem: buried, wet splices that corrode and fail. A hub enclosure keeps connections serviceable and reduces repeat failures.

Why hub enclosures matter

  • Corrosion control: many lighting failures are not fixtures, they’re wet splices.
  • Serviceability: repairs are faster when splices are accessible and centralized.
  • Cleaner upgrades: easier to add fixtures, adjust loads, or re-balance runs.

Service-first reality: a hub enclosure isn’t just a “box”—it’s a work area. When you’re troubleshooting in the dark, having a clean, accessible place for connections prevents lost hardware and repeat splice work.

When we recommend a hub

  • Intermittent sections: lights that flicker or work only after rain/dry spells.
  • Multiple branch runs: one transformer feeding several runs across a property.
  • Recurring splice failures: repeated re-splicing in the same area.
