Tamper Resistant Outlets Installation & Upgrades

Your Guide to Safer Homes

At Bierlein-Trombley Electric, we understand that safety is a top priority, especially if you have young children or curious pets. Tamper resistant outlets are a simple way to protect your home, but you might have questions about their benefits, costs, or installation. We’re here to answer all your questions honestly, so you can make the best choice for your family.

Tamper resistant outlets are designed with built-in safety shutters that block foreign objects from being inserted, reducing the risk of electrical shock and injury. They are now required by electrical code in most living areas of new and remodeled homes, making them an important upgrade for both safety and compliance. Whether you’re replacing a few outlets or updating your entire home, BTE Electric installs tamper resistant outlets correctly and efficiently, giving you added peace of mind without disrupting your space.

What Are Tamper Resistant Outlets?

Tamper resistant outlets (TROs) are electrical outlets with built-in safety mechanisms that prevent objects from being inserted into the slots. They have internal shutters that only open when a plug is inserted with equal pressure on both sides, making it nearly impossible for kids to insert items like paperclips or keys. Required by the National Electrical Code (NEC) in new homes since 2008, TROs are a must-have for childproofing.

It’s a simple, built-in safety feature – no need for plastic outlet caps or covers.

Common Questions About Tamper Resistant Outlets

Q. How Much Does It Cost to Install Tamper Resistant Outlets?

ANSWER: Replacing one or two tamper resistant outlets typically costs $50 to $75 per outlet, depending on wiring conditions and location. For whole-house installations, where we replace a larger number of outlets, the cost drops to $20 to $40 per outlet, saving you money. At Bierlein Trombley Electric, we provide a free, no-obligation quote after inspecting your home, with no hidden fees.

ANSWER: If you have children or grandchildren, TROs are a game-changer. They significantly reduce the risk of electrical shocks or burns from foreign objects being inserted into outlets. Even if you don’t have kids, TROs add an extra layer of safety and may be required for code compliance in certain renovations.

ANSWER: Plastic outlet covers/caps are a budget-friendly option, but they can be removed by determined kids and don’t offer foolproof protection. TROs are built into the outlet, providing permanent, hassle-free safety without compromising usability. While covers are cheaper, TROs are a long-term, reliable solution.

ANSWER: Technically, yes—but unless you’ve got solid experience with outlet wiring, it’s best to leave it to a pro. We’ve seen too many DIY jobs where the outlet was installed backwards, ungrounded, or worse. A licensed electrician will make sure each outlet is:

  • Properly grounded
  • Connected to the correct side of the circuit
  • Labeled (especially if part of a GFCI or AFCI system)
  • Installed safely and cleanly


Problems to Watch Out For

While tamper resistant outlets are highly effective, there are a few things to keep in mind:

  • Poor-Quality Outlets: Low-cost TROs may have weak shutters that wear out over time, reducing their effectiveness.
  • Improper Installation: Incorrectly installed outlets can lead to electrical issues or fail to provide the intended safety.
  • Outdated Wiring: Older homes may need wiring upgrades to support TROs safely.
