About this file

Written by GovTribe AI ·

This file is a technical electrical schematic diagram related to a lighting cabinet service opportunity in Kentucky. The document illustrates a 240-480 volt base mount electrical system design for 2026, depicting a comprehensive single-phase 480-volt service configuration with multiple circuit protection and control mechanisms.

The schematic details a system featuring a 1.0 KVA dry type transformer that steps down 480 volts to 120 volts for control circuits, a main contactor, circuit breaker protection, and a photoelectric control mechanism for automated operation. The design includes nine distinct circuits: circuits 1-4 and 6-9 are rated at 20 amps each, while circuits 5 and 8 are rated at 200 amps each. The system incorporates lightning arrestors on the secondary, a 6-amp fuse arrangement, a light cabinet switch, duplex GFI outlets, a 15-amp neutral fuse, and a manual-off auto switch configuration. This technical specification establishes the electrical infrastructure requirements for the lighting cabinet procurement, though the document does not provide information regarding pricing, quantities required, delivery schedules, or contract award details.
