Replace Cave Lighting System

This projected removed and replaced the existing 2400 volt primary power system, low voltage distribution system, transformers, control panels, distribution panelboards, conduit wiring, lighting circuits and fixtures. The age of the system and high humidity cave environment caused extreme deterioration of the system causing unsafe conditions to the staff, visitors, and were an environmental hazard to the natural cave resources. Existing power, control panels, and light fixtures were not properly grounded, corrosion, unnatural light and heat created biological issues. The system did not comply with National Electric Code requirements. Once the original system was removed, new system was installed. This rehabilitation included: a new primary power system including new conductors, and conduit; a new distribution panels, lighting control panels including panels, disconnects, and transformers. A new secondary power system was installed, including conductors, conduit, and accessories. New light fixtures for trail lighting and Cave feature lighting were installed. Concrete walks in the Cave were replaced, having to remove prior walks to replace embedded conduit and wiring. The backup generator was replaced as well with a properly sized generator, along with a new transfer switch and distribution panelboard.
