Electrician Services » Commercial Electrical Services » Commercial Electrical Services FAQs: Answers from a Master Electrician | CoHarbor Electric
If you run a business in Fort Myers, you already know that electricity keeps everything moving. It’s what powers your lights, computers, coolers, and the equipment your team relies on every single day.
At Coharbor Electric, we work with all kinds of local businesses — from small shops and restaurants to offices, medical practices, and light industrial spaces. We get a lot of questions from business owners who just want straight answers about their electrical systems.
Here are the most common ones — and what you really need to know.
They might look similar on the surface, but commercial electrical work is on a whole different scale.
Commercial systems are built to handle bigger loads, run longer hours, and power heavy-duty equipment. They often include:
3-phase power for larger systems
Backup generators and transfer switches
Exit and emergency lighting
Sign and parking lot lighting
Fire alarm integration
Security and access wiring
It’s not just about pulling wire — it’s about designing a system that runs safely and reliably in a business environment, with all the right permits and inspections.
Pretty much anything with power running through it. Some of our common projects include:
Tenant build-outs and remodels
Restaurant and retail wiring
Office and medical space upgrades
Panel replacements and 3-phase conversions
Lighting design and installation
Warehouse and light industrial power
Preventive maintenance and troubleshooting
We’ve worked on everything from small cafés on McGregor Blvd to large complexes off Colonial.
A few signs usually give it away:
Breakers trip when you’re busy
Lights dim when equipment turns on
Outlets buzz or feel warm
Old fuse panels or aluminum wiring
Corrosion inside your panel
You’ve added new equipment without new circuits
If you’re seeing any of that, it’s worth having your system checked. We’ll run a load calculation to see if your panel can still keep up — and if not, we’ll design a solution that fits your building and your budget.
For most commercial properties, once a year is a good rule of thumb.
If you’re running heavy equipment, refrigeration, or 24-hour operations, every six months is safer. Regular maintenance helps prevent outages, overheating, and those Friday-afternoon surprises that shut you down before the weekend.
Annual checks keep most systems humming—but retail spots need more. Stay outage-free in your Fort Myers store with our Maintenance Plans for Retail.
Think of it like checking your electrical “budget.”
A load calculation tells us how much current your business actually uses and how much your system can safely handle. It’s how we make sure you’re not overloading your circuits — or wasting power.
We run these anytime a business is adding equipment, expanding, or upgrading their panel.

Yes — almost always.
That includes new circuits, panel upgrades, remodels, signs, and generator installs. We handle all the permitting and inspection work directly with the City of Fort Myers or Lee County, so you don’t have to deal with the red tape.
3-phase power delivers smoother, more efficient electricity — which means:
Less strain on motors and compressors
Lower energy costs
Better performance for heavy equipment
More capacity for future growth
If your shop or facility is still running on single-phase, upgrading can make a big difference in reliability and cost.
Amp ratings explained in our Electrical Panels FAQ.
Most electrical fires start small — from loose connections, worn wires, or old breakers that don’t trip properly.
Here’s what helps prevent them:
Yearly inspections
Replacing outdated panels (like Federal Pacific or Zinsco)
Installing AFCI breakers where needed
Keeping panels dry, clean, and accessible
Using thermal scans to catch hotspots early
We include these checks in all of our maintenance plans.
Every build-out starts with a load assessment and design. Then we handle wiring, lighting, outlets, panels, and permits — coordinating with your contractor and city inspectors along the way.
Once the rough-in work passes inspection, we trim it out, test every circuit, and make sure everything meets code before you open your doors.
Absolutely. Power problems don’t care about business hours.
We offer 24/7 emergency electrical service across Fort Myers and Lee County for:
Breaker or panel failures
Equipment outages
Storm-related damage
Power loss during operating hours
Our techs respond fast — we know every minute counts when your business is down.
Timeline for your office in our Repair FAQ for Businesses.
Yes, and in a good way.
Insurance companies love to see modern, code-compliant electrical systems. Upgrading panels, wiring, and safety devices can lower your fire risk — and sometimes even your premiums.
If your business runs electronics — and especially if you’re in Fort Myers — then yes.
Lightning strikes and grid surges happen here all the time. A single spike can fry computers, point-of-sale systems, or refrigeration controls. We install commercial-grade surge protectors that shield your main panel and sensitive gear.
