- Panels, subpanels and added capacity for tenant improvements and new equipment
- Dedicated circuits and 240V outlets for compressors, ovens, coolers, machines and battery chargers

- Troubleshooting and repair when half the building loses power or a breaker won't hold
How commercial jobs run
You get a walkthrough and a written estimate, then a schedule that works around your busiest hours where we can. We pull the permit when the work needs one, keep the work area clean and safe while you're open, and label everything we touch so the next electrician, or your landlord, can read the panel. Most jobs finish with a walkthrough and a one-year warranty on parts and workmanship.
