Commercial electrical
wiring in Tulsa, OK.

Commercial wiring costs vary significantly based on project scope, building size, and specific requirements. A simple tenant improvement with a few new circuits typically starts around $2,000. A mid-sized office build-out runs $15,000–$40,000. Complete electrical for new commercial construction can range from $10–$30 per square foot installed depending on use type, code requirements, and finish level. Industrial or restaurant projects with heavy load and specialty equipment can reach $100,000+. Contact us for a detailed quote tailored to your specific scope.

Yes, significantly. Commercial electricians work with three-phase power, larger conductor sizes, industrial-grade equipment, conduit-based wiring methods, and complex commercial building codes. They handle distribution panels in the 200A–4000A range, motor controls, fire-alarm interfaces, life-safety systems, and coordination with other trades on a job site. Commercial work also requires familiarity with bid documents, RFIs, change orders, and submittals. M Electric's commercial electricians carry certifications and ongoing training specifically for commercial applications.

Commercial buildings typically use heavy-duty wiring methods that meet NEC and local Tulsa code: THHN/THWN-2 copper conductors run in EMT (electrical metallic tubing) or rigid conduit; MC (metal-clad) cable for plenum or concealed runs; armored cable in some applications; and specialty cable types for fire-alarm, data, and emergency systems. Conductor size is engineered based on load calculations, voltage drop, and ambient temperature. All wiring must meet local Tulsa building codes and NEC requirements.

In most Tulsa commercial settings, yes. Commercial electrical codes typically require wiring to be protected by appropriate conduit systems for safety and durability. Specific requirements vary by jurisdiction and application — exposed wiring is generally only allowed in concealed plenum spaces or with armored cable in specific applications. Our team handles the code research as part of any project, so you don't have to navigate the requirements yourself.
