From its Corte Del Nogal office in Carlsbad's Aviara corridor, Arrowhead Electric delivers electrical contracting across hospitality, healthcare, entertainment, and commercial sectors. New-construction and tenant-improvement projects require load calculations, conduit routing, and panel sizing that interface directly with mechanical trades — particularly HVAC contractors such as Coastal Refrigeration Heating and Air Conditioning on commercial package-unit installations. The portfolio includes infrastructure builds for office complexes, retail centers, and residential communities throughout San Diego County. Exterior electrical scopes encompass parking-lot LED pole-light retrofits, exterior signage circuits, and landscape-lighting transformer installations — outdoor phases that intersect with commercial site work from Armstrong Garden Centers on planting and hardscape projects. The most complex engagements involve 480/277-volt three-phase switchgear installations, emergency generator automatic-transfer-switch integration, and healthcare-grade isolated-ground wiring per NEC Article 517 for medical facility construction.
