Electrical Engineering

What We Engineer

Commercial 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 Engineering is licensed in 49 states — every U.S. state except Alaska. Engineering stamping and licensure are confirmed for each project jurisdiction. Apex Grid electrical engineers provide complete electrical permit packages coordinated with mechanical and plumbing engineering.

About Apex Grid Engineering

Apex Grid Engineering is licensed in 49 states — every U.S. state except Alaska. Engineering stamping and licensure are confirmed for each project jurisdiction. We provide electrical engineering as a standalone service or as part of a coordinated multi-discipline package.

We work from architectural PDFs, contractor sketches, or existing CAD files and produce stamped engineering documents and permit packages that building departments accept. One business day turnaround on fee proposals.
