Common Electrical Issues in Reno Commercial Buildings—And How to Fix Them

Running a business in Reno means maintaining more than just day-to-day operations—you also need to keep your commercial property safe and functional. One area often overlooked until problems arise is the electrical system. Faulty wiring, outdated panels, and overloaded circuits can cause expensive downtime or even pose safety risks. In this post, we’ll go over the most common electrical issues in Reno commercial buildings—and how a licensed commercial electrician can help fix them.

Flickering or Dimming Lights

What It Means:

Flickering lights are often caused by loose wiring, overloaded circuits, or issues with the electrical panel. In some cases, it may also be due to faulty light fixtures or ballast failure in fluorescent lighting.

How to Fix It:

A commercial electrician will:

• Inspect wiring and replace any loose or frayed connections

• Assess circuit loads to redistribute power if needed

• Upgrade ballasts or fixtures if necessary

Overloaded Circuits and Breaker Trips

What It Means:

When too many appliances or devices draw power from a single circuit, it can cause breakers to trip. This is especially common in businesses that rely heavily on computers, printers, HVAC systems, or industrial equipment.

How to Fix It:

• Rewire to redistribute power across multiple circuits

• Upgrade the electrical panel to increase load capacity

• Install dedicated circuits for high-demand equipment

Outdated Wiring

What It Means:

Many older Reno buildings still have aluminum or knob-and-tube wiring, which no longer meets current safety codes and can increase fire risk.

How to Fix It:

• A complete rewiring may be necessary to bring the building up to code

• The electrician will also check grounding and bonding for safety

Inconsistent Power or Power Loss

What It Means:

If your business experiences frequent power loss or fluctuating voltage, it could be a sign of faulty wiring, a failing transformer, or damage to the main electrical service.

How to Fix It:

• Test all major connections and replace any failing components

• Work with NV Energy if utility supply issues are suspected

• Add surge protection and voltage regulation systems if needed

Electrical Code Violations

What It Means:

Improper installations, lack of GFCI/AFCI outlets, exposed wires, or outdated panels can all be violations of the National Electrical Code (NEC) and Nevada energy compliance standards.

How to Fix It:

• Conduct a full electrical code compliance inspection

• Update outlets, panels, and wiring to meet current NEC guidelines

• File necessary permits and schedule inspections

Inadequate Lighting for Commercial Spaces

What It Means:

Poor lighting can affect safety, employee productivity, and customer experience. This is often due to outdated fixtures, poor layout, or insufficient power delivery.

How to Fix It:

• Retrofit existing lighting with energy-efficient LED solutions

• Redesign the lighting layout for optimal brightness and energy usage

• Install dimmers, timers, and occupancy sensors

Faulty Outlets and Dead Switches

What It Means:

If outlets or switches don’t work, it could be due to broken components, internal damage, or circuit wiring issues behind the wall.

How to Fix It:

• Replace faulty outlets and switches

• Inspect behind-wall wiring for damage or corrosion

• Ensure grounding and proper amperage for safety
