Corbin Electrical Services, Inc. has provided comprehensive residential electrical services to Monmouth, Middlesex, and Ocean Counties in New Jersey for over 45 years.

You should never use an extension cord in the following situations:As Permanent WiringExtension cords are intended for temporary use. If you rely on one every day, it\u2019s time to install a proper outlet instead.Behind WallsNever run an extension cord through walls, ceilings, floors, or crawl spaces. These cords are not made for concealed installation and can overheat, increasing the risk of fires.When CookingHigh-powered kitchen appliances, such as toaster ovens, air fryers, and microwaves, should plug directly into an outlet. Extension cords may not be equipped to safely withstand their electrical load.In Wet or Damp AreasWater and electricity don\u2019t mix. Avoid using standard extension cords in bathrooms, unfinished basements, garages, or outdoors, unless they are specifically rated for those conditions.When Plugging in Multiple DevicesOverloading an extension cord with several devices can generate excessive heat and increase the risk of a fire. Each cord has a maximum electrical capacity that you shouldn\u2019t exceed.When Styling Your HairHair dryers, curling irons, and flat irons draw significant power. Plug those heat-styling tools directly into a properly grounded bathroom outlet protected by a Ground-Fault Circuit Interrupter (GFCI).Under Rugs, Carpets, and FurnitureCovering an extension cord traps heat and makes it hard to tell if it\u2019s damaged. Furniture can also pinch or crush the cord, damaging its insulation over time.With Major AppliancesRefrigerators, freezers, space heaters, air conditioners, washers, and dryers should always be plugged directly into dedicated outlets. These appliances require more power than most extension cords can carry.If It Has Frayed WiresNever use a damaged extension cord. Replace the cord immediately if you notice cracked insulation, exposed wiring, loose plugs, or bent prongs.When Charging an Electric Bike or ScooterCharging batteries generates a lot of heat. Plug chargers directly into a wall outlet whenever possible to reduce the risk of overheating.For Outdoor Use (Without the Proper Rating)Indoor extension cords can\u2019t withstand moisture, sunlight, or temperature changes. Always choose an extension cord specifically rated for outdoor use when working outside.When Connecting Power Across the HouseRunning long extension cords from one room to another creates tripping hazards and puts unnecessary strain on your electrical system. Putting in additional outlets is a safer solution.If the Cord Is Too LongUsing a cord that\u2019s longer than necessary can reduce efficiency and create excess heat. Choose the shortest cord that safely reaches your equipment.Extension Cord Safety TipsIf extension cords have become part of your daily routine, your home\u2019s electrical system may no longer meet your needs.
