Most offices plan for fire safety, data backups, and security. Surge protection often makes the list too; with a power strip under nearly every desk. The intention is right, but consumer-grade strips only go so far, and the devices running your business every day may be more exposed than you’d expect. As a provider of commercial electrical services in Deland, FL, Deltron Electric has seen what a single unprotected surge event can do to a fully operational office, even one that thought it had its bases covered.
What’s a Power Surge?
A power surge occurs when voltage spikes above normal levels. Lightning is the most well-known cause, but internal sources like HVAC systems, elevators, and large equipment cycling on and off are responsible for the majority of surges most buildings experience. It can last a fraction of a second, but that’s enough to damage or destroy sensitive electronics.
These are the five devices most likely to take the hit when a surge runs through your building.
1. Computers and Workstations
Desktops and laptops top the list. A minor surge can corrupt hard drives, damage motherboards, or wipe out unsaved work in an instant. Whole-office surge protection at the panel level is far more reliable than relying on individual power strips, which vary widely in quality and protection rating.
2. Servers and Network Equipment
Your server room is the nervous system of your business. Routers, switches, and on-site servers are particularly sensitive to voltage irregularities. A single unprotected surge event can take down your entire network and compromise stored data. The cost of replacing this equipment (and recovering lost files) far exceeds the cost of prevention.
3. Phone Systems and Communication Hardware
VoIP systems, PBX units, and multiline phone systems are often overlooked when businesses think about surge risk. These devices run on sensitive circuit boards that can be damaged by even moderate spikes. Losing your phone system mid-business-day means missed calls, missed clients, and missed revenue.
4. HVAC Control Systems
Modern HVAC systems run on digital controllers and smart thermostats, all of which are vulnerable to surges. Surges knock them out, shutting down cooling; and in a Florida summer, that’s not just uncomfortable, it’s a health hazard. Surge protection at the panel level helps shield these controllers from voltage spikes, whether from lightning, utility switching, or large equipment cycling on and off.
5. Copiers, Printers, and Multifunction Devices
These machines have more circuit boards than most people realize. High-end copiers and multifunction printers are expensive to replace and slow to repair. They’re also frequently plugged into standard outlets without dedicated surge protection, making them quietly vulnerable.
Answers to Power Surge Questions We Often Get Asked
Q: Does building wiring impact surge risk?
A: Absolutely. Older or improperly grounded wiring increases your exposure significantly. Facility wiring and service upgrades can address outdated infrastructure that leaves your equipment more vulnerable during voltage events.
Q: Do power strips with surge protection actually work?
A: Some do, to a degree. But consumer-grade strips offer limited joule ratings and no whole-building protection. Panel-level surge protection is a more dependable solution for commercial environments.
Q: Can a power surge create safety risks beyond damaged equipment?
A: Yes. Surges can damage wiring insulation inside your walls, increasing the risk of electrical fires over time. In severe cases, exposed or compromised wiring can also pose a shock risk to anyone who comes into contact with affected outlets or devices. Any surge that trips breakers, causes visible scorching, or leaves a burning smell behind should be inspected by a licensed electrician before the space is used as normal.
