Unexpected power surges can put your business at risk. One moment, your equipment is running fine. Next, you’re dealing with flickering lights, tripped breakers, or worse, damaged machinery and downtime.
If you own or manage a commercial property, you can’t afford to ignore electrical problems. Here’s what you need to know about power surges, the risks they pose, and when it’s time to call an emergency electrician for businesses.
What Is a Power Surge?
A power surge is a brief but intense spike in electrical voltage that moves through your wiring.
Most commercial systems in the U.S. operate on 120 volts. A surge occurs when that voltage suddenly increases, sometimes to hundreds or even thousands of volts. This may last less than a second, but the damage can be instant and costly.
Surges aren’t just about blown fuses or blackouts. They disrupt the normal flow of electricity and put stress on anything connected to your system. That includes:
- Computers and servers
- Industrial machines
- HVAC systems
- Lighting controls
- Security systems
Many power surges go unnoticed. The lights don’t go out. The system reboots. But each surge adds wear and tear.
Common Causes of Power Surges in Commercial Properties
Power surges happen for several reasons. Understanding the source can help you respond faster.
-
Lightning Strikes
A direct or nearby lightning strike can send a massive surge through power lines. This is more common in storm-prone regions.
-
Utility Grid Switching or Failures
When your electric company switches between grids or restores power after an outage, voltage can spike suddenly.
-
Large Equipment Cycling On and Off
Elevators, HVAC units, and industrial machines pull a lot of power when starting up. This repeated demand can cause internal surges.
-
Wiring Issues
Outdated or overloaded electrical wiring increases the risk of surges and other electrical hazards.
-
Faulty Outlets or Breakers
Loose connections, corroded terminals, or faulty circuit breakers can disrupt current flow and trigger surges.
Warning Signs of a Power Surge
Many businesses don’t notice a surge until something stops working. But some warning signs can help you act early:
- Sudden loss of power followed by rebooting electronics
- Flickering lights or blinking displays
- Burnt smell near outlets
- Tripped breakers or blown fuses
- Devices overheating without heavy use
- Unusual noise or humming from panels
If you spot any of these signs, don’t wait. Repeated surges can escalate into a serious electrical emergency.
What’s at Risk During a Power Surge?
Power surges can affect more than just devices. The longer the delay in addressing them, the higher the risk of:
-
Data Loss
Servers and computers can crash or get corrupted. If your business relies on digital records, this can be devastating.
-
Equipment Damage
Expensive machines, printers, point-of-sale systems, or HVAC units can fail after even one large surge.
-
Operational Downtime
Every hour without power or with damaged systems means lost revenue and productivity.
-
Fire Hazards
Damaged wiring and overloaded circuits increase the risk of electrical fires, especially in older buildings.
-
Customer and Staff Safety
Malfunctioning lights, alarms, or ventilation can create unsafe conditions for anyone on-site.
Can Surge Protectors Fully Prevent Damage?
Basic surge protectors offer limited protection, but they’re not designed for the demands of a commercial electrical system.
Most cheap power strips can’t handle large voltage spikes and may fail when you need them most. Even higher-quality units lose effectiveness over time as their internal components degrade.
Additionally, many surge protectors only shield the devices directly plugged into them, leaving the rest of your system—including hardwired equipment and panels—exposed.
To protect an entire building, consider whole-building surge protection systems. But even these can’t help if your wiring is outdated or poorly maintained.
If you already have surge protection but still experience issues, your electrical system needs to be inspected.
When to Call an Emergency Electrician for Businesses
Some situations need immediate action. Don’t wait until regular business hours if you see:
- Smoke or burning smells from outlets or panels
- Sudden and unexplained loss of power
- Sparking outlets or scorched faceplates
- Constant breaker trips even after resets
- Power surges during storms or after an outage
- Critical systems like security, alarms, or HVAC are failing
A qualified emergency electrician for businesses can quickly identify the cause, restore safe power, and prevent further damage. Waiting too long puts your property, your equipment, and your people at risk.
What an Emergency Electrician Will Do
A licensed commercial electrician will:
- Inspect your wiring, breakers, and surge protection
- Test circuits and identify overloads or short circuits
- Check panel capacity and grounding
- Repair or replace faulty equipment
- Restore power safely without cutting corners
They may also recommend updates, such as upgrading outdated wiring or installing a surge protection system rated for your business’s needs. You get peace of mind knowing the issue was handled by a professional.
How to Reduce the Risk of Future Surges
You can’t eliminate every power surge, but you can take steps to reduce the damage. Small, preventive actions go a long way in protecting your equipment, avoiding costly repairs, and keeping your business running smoothly.
-
Schedule regular inspections
Inspections catch early issues before they lead to surges. Older buildings especially need frequent checks.
-
Upgrade old wiring and panels
Outdated systems can’t handle modern loads. Upgrades reduce the risk of overheating and surges.
-
Use surge protectors for key devices
They help block small surges from reaching sensitive equipment. Ideal for computers, POS systems, and monitors.
-
Install whole-building surge protection
This protects your entire system from external spikes. It works at the panel level for full coverage.
-
Don’t overload outlets or daisy-chain cords
Too many plugs in one outlet strain the system. Extension cord chains are also a fire risk.
-
Train staff to report issues
Encourage reporting of flickering lights or strange behavior. It helps catch problems early.
-
Proactive is cheaper than reactive
Prevention costs less than replacing damaged equipment. It also avoids unexpected downtime.
