Electrical engineering designs the power distribution, lighting, emergency power, and specialty electrical systems for commercial buildings. Apex Grid electrical engineers produce PE-stamped permit drawings for commercial, industrial, multifamily, and government projects — from electrical service sizing and one-line diagrams through solar interconnection, EV charging, and emergency power design.
Request Engineering SupportCommercial electrical engineering covers the design of power distribution systems — from the utility service entrance through the main switchgear, distribution panels, branch circuits, and end-use equipment. It also encompasses specialty systems: emergency generators, battery storage, solar PV interconnection, EV charging, arc flash analysis, and low-voltage systems. Apex Grid electrical engineers are multi-state team; project availability and stamping are confirmed per project after individual license, firm authorization, discipline, and AHJ requirements are verified and provide complete electrical permit packages coordinated with mechanical and plumbing engineering.
