From Residential Electrical Work to Commercial & Industrial Expertise, RB Delta Electric began eight years ago with residential electrical work: rewiring, panel upgrades, new construction wiring and emergency calls. That foundation grew into semi heavy commercial and industrial installations including switchgear, step up transformers, raceway and EMT conduit, general lighting and power distribution. Today, the same contractor (C-10 license # 1046368) handles homes, businesses and industrial facilities under one license, with a written scope and an honest appraisal of the work your property genuinely needs.
