Perry Electric in Santee is a third-generation C-10 electrical contractor operating under CSLB license #747931 from its Woodside Avenue headquarters since the firm's founding in 1968. Underground conduit installation for traffic signal intersections and freeway lighting systems requires trenching coordination with site-work contractors such as Accurate Grading & Paving on Argent Street, where subgrade preparation precedes Perry's conduit runs for vehicle loop detection and CCTV camera feeds. The firm's scope covers complete traffic intersection construction including poles, signal heads, mast arms, luminaires, and controller cabinet wiring, along with highway communication systems, fiber optic backbone installation, and Intelligent Transportation Systems featuring Variable Message Signs, blankout signs, and parking guidance electronics. Perry serves municipal and Caltrans contracts across San Diego and Imperial counties, with directional drilling capabilities for conduit placement beneath existing roadways without surface disruption. Solar-powered traffic flasher arrays and battery-backup signal cabinets share the renewable-energy intersection with photovoltaic contractors such as Higher Power Solar on Mission Gorge Road. Highest-complexity projects involve multi-intersection corridor signal coordination with Type 2070 or NEMA TS-2 controller programming and SDG&E utility interconnection for medium-voltage street lighting circuits.
