Unique Direct Burial Composite Enclosure transformers are engineered for concealed, in-ground low-voltage lighting installations. Fully potted and sealed, these units protect internal electrical components from moisture, soil, and corrosive environments while delivering stable multi-tap secondary voltages for landscape and architectural lighting systems.

Watts & models: Available in 300W and 600W capacities to power multiple fixtures or larger commercial runs; select the model that matches your load and run-length requirements.
Durable construction: Injection-molded, glass-filled resin housing with UV-resistant finish and molded silicone gasket for a weather-tight seal in subterranean installations.
Protected design: Fully potted and sealed enclosure with replaceable 3AG time-delay primary fuse and optional secondary in-line fusing to reduce nuisance trips and protect circuits.
Output & wiring: Ready-to-wire, color-coded 10 AWG output leads provide clear connections; multi-tap secondary voltages vary by model—consult model specs for exact taps.
Installer features: Separate primary and secondary compartments, conduit flats on all four sides, and a 1/2"-14 NPSM threaded center lid hole for mounting fixtures or accessories.
Performance & warranty: Engineered single-core construction with welded output taps for reliable conductivity; unit must be hardwired to 120V primary and includes a limited lifetime warranty against manufacturer defects.

These transformers are ideal for residential and commercial projects where concealing the power source is necessary. Installation must be completed by a qualified electrician; always verify model-specific secondary tap voltages, dimensions, and weight before installing to ensure compatibility with your lighting layout.
