How to Choose The Right Electrical Panel for Your Business
The modern workplace depends more heavily on power-hungry appliances than ever before, from servers and office electronics to HVAC units, refrigeration systems, and other specialized equipment. All that hardware can put tremendous strain on a building’s electrical system, pushing outdated components to their limits and beyond.
If your facility’s electrical panel is too small to handle daily demand, your business could be in trouble. Undersized panels can lead to equipment damage, service disruptions and unscheduled downtime that costs you money, to say nothing of the potential safety hazards. The warning signs aren’t always obvious, but we’ve got you covered with everything you need to know.
Why Electrical Panel Sizing Is a Big Deal
The main service panel is the nerve center of a building’s electrical system, drawing electricity from the grid and distributing it to the circuits running throughout the facility. The size of the panel, also known as its amperage, effectively determines how much total current it can safely provide to power all your business’ fixtures, appliances and equipment.
Think of it like a bridge on a busy highway, with the size of the panel representing the number of lanes available. The more power your business uses, the more cars there are on the road. At a certain point, the volume of traffic simply exceeds what the bridge can support.
What’s more, constantly exposing a bridge to heavy traffic may cause greater wear and tear and increase the risk of accidents and other issues. Regularly pushing an undersized electrical panel to its limits is similarly risky. That’s why the National Electrical Code stipulates that continuous loads should never exceed 80% of the rated capacity.
Service panels come in many sizes, so it’s important to ensure yours is properly rated for your needs.
As a general rule of thumb, recommended ratings for common applications include:
- 60-100 A: Cabins and older homes with few appliances
- 150-200 A: Typical modern homes and professional offices
- 225-300 A: Retail stores, office buildings and small restaurants
- 400 A: Mid-sized restaurants, commercial buildings and warehouses
- 600+ A: Large commercial and industrial facilities with three-phase power
Signs Your Commercial Electrical Panel Is Too Small
So, how can you tell if you’re asking too much of your service panel? While there are usually plenty of red flags, some are more obvious than others. Let’s take a look at a few of the warning signs you can’t afford to miss.
Trouble With Tripping Breakers
Occasionally overloading a circuit and tripping a breaker is a fairly innocuous slip-up. In fact, it’s reassuring to know that your electrical system’s working as intended. If you find yourself making regular trips to the breaker panel, however, the usual “reset it and forget it” strategy just won’t cut it.
Not only are frequently tripping breakers annoying and disruptive, but they can degrade reliability by weakening internal components. Simply put, they’re your panel’s way of signaling that it’s overmatched and in need of an upgrade.
Dimming or Flickering Lights
You don’t need to be a master electrician to know it’s bad news when the lights inside your building start acting up out of the blue. This usually happens because certain appliances require a lot of power on startup, producing a spike in demand that may briefly overwhelm a breaker panel already operating near full capacity.
The result is a short, sudden dip in power going to the light fixtures, causing them to flicker or dim. It’s a clear sign your panel isn’t properly sized for your electrical system, but it can also create an unfavorable impression of your business.
Excessive Heat Buildup
Heat is the archenemy of electrical systems. It degrades metal parts, damages wire insulation and greatly enhances the danger of faults, fires and other failures. Unfortunately, it’s also a natural and unavoidable byproduct of an overworked and underpowered electrical system.
Consequently, an easy way to monitor the status of your service panel is to gently feel the cover and individual breakers with the back of your hand. While it’s not unusual for the components to feel slightly warm on occasion, they should never be hot to the touch. Other signs of trouble include visible discoloration or scorch marks and a hot, acrid odor near the panel.
Heavy Use of Power Strips
Extension cords, wall taps and power strips are undeniably convenient in a pinch, but they simply aren’t meant for heavy, prolonged use. Routinely relying on these temporary solutions can lead to serious code violations and insurance issues, and for good reason. Not only does it create tripping hazards in a busy workplace, but it also increases the likelihood of overloaded circuits, equipment damage and electrical fires.
A safer, more permanent solution is to install additional outlets wherever they’re needed. Of course, that option depends on your existing panel having enough capacity to spare. Speaking of which..
Limited Expansion Capacity
An undersized electrical panel isn’t just a pain to deal with in the present. It’s also a limitation that can prevent your business from growing in the future. Smaller panels have less spare capacity and fewer slots for circuit breakers, making it much harder to install new equipment, upgrade your building or add more outlets and fixtures.
Even if your current electrical demand is being met, that may not always be the case. Proactively upgrading a panel with limited room for expansion is a savvy future-proofing move, providing peace of mind and ensuring your business is ready for whatever’s ahead.
Invest in Professional Electrical Panel Upgrades
Has resetting tripped breakers become a routine part of your job description? Are you tired of counting circuits and stressing over load calculations every time you add a new piece of hardware? If your current service panel isn’t cutting it, it’s time to call your local pros and install a high-quality upgrade built to meet your needs.
While the installation itself is fairly straightforward, it requires diligent planning and preparation. Working with expert electricians takes the guesswork out of upgrading your panel, ensuring you find the solution that best fits your business and budget.
A qualified contractor can seamlessly manage every step of the process, including:
- Analyzing energy usage and performing load calculations
- Recommending and sourcing high-quality components
- Removing and replacing all existing hardware
- Handling permits and verifying code compliance
- Testing panel and circuits for proper functionality
