Commercial Electrical Rough-In: What’s Involved & Cost

Commercial electrical rough-in occurs after framing and before drywall installation, establishing the complete wiring infrastructure for a building. Work includes running conduit and wire for lighting circuits, receptacles, dedicated equipment circuits, and data cabling. Commercial rough-in requires larger wire gauges, conduit protection, and more complex circuit layouts than residential work. ESA inspection is required before covering walls. Costs range from $5-$15 per square foot depending on electrical density and equipment requirements. Proper rough-in planning prevents costly changes during finishing stages.

An electrician will be able to see the big picture of your commercial space and identify all the places that require new electrical services or circuits. They can also handle everything from installing new circuit breakers in a subpanel to running new electrical cables through walls and ceilings. Read on to learn more about what an electrician can do for you when it comes to your commercial electrical rough-in project.

Identify New Services and Circuits

When you start building a new commercial space, you’ll need to install new electrical services to power the lights, appliances, and other electrical devices in your building. However, you may not always know what types of services you’ll need to install. For example, if you’re planning to install a new retail space and have a designated area for a cashier, you’ll likely need to install a new circuit for their register.

If you don’t hire an electrician to identify your services and circuits during the rough-in phase, you’ll have to shut down your construction site and hire another contractor to come in and do the job after the walls are up.

Install New Breaker Panels and subpanels

During the electrical rough-in phase, your electrician will install new subpanels or breaker panels throughout your commercial space. A subpanel is a smaller panel that handles just a few circuits. Breaker panels, on the other hand, are large panels that control the power for an entire section of the building.

If you’re building a new space from the ground up, you may want to consider installing a subpanel for each section of the building. That way, if one section fails, you can shut off that subpanel and keep the other areas running.

Install New Wiring

Whenever you’re building a new space, it’s a good idea to replace all the electrical wiring in the walls and ceilings. This will prevent any power issues that could be caused by aging wiring. If you want to keep your building safe, you’ll want to make sure the wiring adheres to current building codes. Your commercial electrician can help you choose the right wiring type, like CL-2 or CL-3 wiring, depending on your local building codes.

Wiring is typically covered in rubber or metal sheathing to protect it from damage. However, when workers are sawing through ceilings and drilling into walls, these areas become exposed, which makes them vulnerable to short circuits. Your electrician can install new wiring and include surge protectors to help protect it from short circuits.

Install Surge Protection

You may have surge protectors installed on your circuit boards that are protecting your circuits from surges in power. However, these circuit boards are not protecting the rest of your building. Your commercial electrician can install new surge protectors throughout your building. These surge protectors will help protect your circuits from surges caused by nearby lightning strikes and utility company issues. They will also help your circuit boards from overheating, which could cause a fire.

Install Existing Equipment Grounding

If you’re converting a space or building out a new section of your building, you’ll need to install grounding to protect your electrical equipment. If you neglect to install grounding, your equipment will be at risk of being damaged by power surges or even causing a fire in your building. You will want to install grounding on the electrical panels, breakers, and equipment, like your refrigeration units. Your commercial electrician can help you decide where to install grounding and how to do it.

Conclusion

An electrician can help you select the right wiring type, install new circuits and subpanels, and install grounding to protect your electrical equipment. If you are in the process of building out a new commercial space, you should hire an electrician for your rough-in project. An electrician will be able to see the big picture of your commercial space and identify all the places that require new electrical services or circuits.

Kitchen Appliance Circuits: Why Dedicated Wiring Matters

Kitchen appliance circuits are dedicated 20-amp electrical lines that power individual high-draw appliances like refrigerators, dishwashers, and microwaves. Ontario Electrical Safety Code requires separate circuits for appliances drawing over 12 amps to prevent overloads and tripped breakers. Modern kitchens typically need 6-8 dedicated circuits, including two 20-amp small appliance circuits for countertop outlets. Proper circuit planning prevents nuisance tripping and ensures safe appliance operation.

Home Electrical Safety: Warning Signs You Need Repairs

Home electrical safety depends on recognizing warning signs that indicate needed repairs. Flickering lights, frequent breaker trips, burning odors near outlets, and warm switch plates all signal potential hazards requiring immediate attention. Homes over 25 years old often have outdated wiring that cannot handle modern electrical loads. Regular electrical inspections every 3-5 years help identify problems before they become fire hazards or cause equipment damage.
