Do Outlets Have To Be Tamper Resistant
Tamper-resistant (TR) receptacles have been a requirement in the Canadian Electrical Code for some time now—but only in specific situations. In this post, we’ll break down where and why they are required, and what the pros and cons are for both TR and non-TR receptacles.
What Are Tamper Resistant Receptacles?
Tamper-resistant receptacles are electrical outlets that include built-in plastic shutters designed to block foreign objects from being inserted. These shutters only open when a proper plug is inserted straight in. They’re often referred to as childproof (and sometimes elderly-proof) outlets.
They’re now mandatory in:
- All new residential dwellings
- Any home renovations where receptacles are added or replaced
Important: These rules apply specifically to dwelling units with sleeping quarters—in other words, your main house.
Where You Do Not Need Tamper Resistant Receptacles
You are not required to install TR receptacles in the following locations:
- Detached buildings (e.g., garages, sheds)
- Countertop plugs in the kitchen
- High-amperage outlets, such as:
- Stove plugs
- Dryer plugs
- Welder plugs
If your garage is attached to the house, TR outlets are required.
Why Use Tamper Resistant Receptacles?
Pros:
- Prevents children from inserting objects like forks, knives, or toys.
- Eliminates the need for plastic child-safety caps.
- Meets electrical code for new builds and most upgrades.
Cons:
- Harder to use: You need to align plugs perfectly and push firmly.
- Can be frustrating for elderly users or people with mobility issues.
- Electricians and clients alike often complain about their inconvenience.
Non-Tamper Resistant Receptacles
These are the traditional outlets most people are familiar with. They allow easy insertion of plugs—but they come with greater risk, especially around children. Stories of accidents due to items being inserted into these outlets are not uncommon, and that’s why safety codes now favor tamper-resistant designs.
Final Takeaway
Like them or not, tamper-resistant receptacles are here to stay—at least in Canadian residential construction. If you’re building, renovating, or replacing outlets in your home, they’re likely required by code. If you’re working on a detached garage or shed, though, you can stick with the standard versions.
