Close Credit: bagi1998 / Getty Images When it comes to caring for your home, electricity often doesn’t get the same attention as fresh coats of paint and seasonal deep cleans. Yet behind your walls and outlets, your electrical system is working to keep your household running smoothly. Unfortunately, some surprising mistakes can force your system to work even harder—or create serious safety hazards. "It takes many years of on-the-job training with simultaneous college-level schooling to be permitted by the state to take your Master Electrical License test," explains professional electrician Brandon Dolan of Dolan Inc., a professional plumbing, heating, cooling, and electric company. "For homeowners, please don’t take electricity lightly—because we professionals certainly don’t." To help you maintain a safer, more functional home, here are the common mistakes professional electricians wish every homeowner would stop making.

Instead, spread your usage across multiple outlets and unplug items when you finish using them. Additionally, you can invest in surge protectors and consider hiring an electrician to install additional outlets if you really need them. 02 of 07 Ignoring Flickering or Dimming Lights Credit: Getty A light that flickers or dims when you run another appliance is more than an inconvenience—it’s a red flag. It may indicate faulty wiring or an overloaded circuit. Don’t wait until the issue worsens; have a professional investigate before it leads to greater damage. "Your outlets and switches can be monitored by being diligent while using them," says Dolan. If lights are flickering, a switch feels "off" when flipping it, or you hear crackling sounds when the lights are in use, "then you need to call a licensed professional," Dolan says. 03 of 07 Neglecting the Electrical Panel Your home’s electrical panel is its control center, but many homeowners neglect it entirely. "The main electrical panel is the area where you need to periodically check for any signs of arcing (or electrical fire damage), water damage penetrating from outside or due to humidity, and proper installations after new work is complete," shares Dolan. Loose wires, dust, and outdated components can lead to issues and electrical fire risk. Have your panel inspected periodically. "In the electrical field, we like to say 'loose wires cause fires,'" Dolan warns. 04 of 07 Treating Extension Cords as Permanent Solutions Credit: Fuse / Getty Images Extension cords are designed for temporary use—not as a replacement for proper wiring. If you rely on them every day, the real solution is installing additional outlets. Also, be sure to inspect (for exposed or fraying wiring) and regularly replace any extension cords that get heavy use. 10 Things to Never Use With an Extension Cord, According to an Electrician 05 of 07 Using the Wrong Wattage Bulbs Credit: Khaosai Wongnatthakan / EyeEm / Getty Images According to Dolan, "DIY electrical work should be limited to changing light bulbs and, if you have experience, changing a light fixture or ceiling fan that’s like for like." And, as for those bulbs—remember that wattage matters. While it's easy to grab whichever bulb is on hand, mismatched wattages can overheat fixtures and damage sockets. Always check your fixture’s recommendations, and consider switching to LEDs for energy savings. 06 of 07 Not Planning for New Appliances Adding a home office, an entertainment center, or an extra-large appliance (say, a hot tub) often requires more electrical capacity than your current setup provides. Instead of straining your existing system, consult an electrician to ensure your wiring can handle the upgrade. 07 of 07 DIY Fixes Without Proper Knowledge Credit: kellymarken / Getty Images As mentioned above, Dolan warns against inexperienced homeowners taking on electrical work themselves. "I can’t tell you the terrible mistakes I’ve seen homeowners and handymen make when it comes to electrical work," he says. Things like rewiring fixtures or troubleshooting the panel should always be left to licensed electricians. "Electricity is not only a dangerous fire hazard but a very serious health risk," says Dolan. "As a homeowner, you need to respect electricity and learn what its potential is." Explore more: Home
