Peterson Electric in Santee operated from Suite B2-405 at 9625 Mission Gorge Road, serving residential and light-commercial clients across San Diego County with panel replacements, fixture installations, and structured wiring for home technology systems. Garage door opener circuits and motorized gate wiring placed the company in coordination with door and screen specialists such as Great American Door & Screen on Prospect Avenue, where dedicated 120-volt branch circuits and safety-sensor wiring must meet UL 325 entrapment-protection standards. The firm's residential scope covered ceiling fan installations, dimmer switch upgrades, whole-house surge protection, security system wiring, and low-voltage structured cabling for home networks. Outdoor landscape lighting projects paired Peterson's low-voltage transformer installations with hardscape and planting designs from landscape contractors such as ARC Design Landscape on Wheatlands Avenue for integrated exterior illumination. The company's panel-upgrade work included replacing obsolete Federal Pacific and Zinsco Sylvania breaker panels with 200-amp Square D Homeline or Siemens load centers meeting current NEC arc-fault and ground-fault branch-circuit protection requirements.
