An electrical outlet is the wall-mounted receptacle that lets you plug in devices to access household power. Most homes use duplex receptacles (two plug-in spots), and you’ll also see specialized options depending on where and how you plan to use them.

• Standard or tamper-resistant: Everyday power, with added safety shutters on tamper-resistant models.
• GFCI outlets: Help reduce shock risk in areas with moisture, like bathrooms and garages.
• USB outlets: Built-in USB-A/USB-C charging so you can skip adapters.
• Wall taps and surge protectors: Expand outlets at the wall and may add surge protection.

When shopping, consider amperage (15A vs 20A), indoor vs outdoor rating, and recognized safety certifications to fit your setup.

In bathrooms, a GFCI outlet is commonly recommended because it can help reduce shock risk in damp areas. Many local codes require GFCI protection near sinks and tubs, but requirements vary, so it’s wise to confirm with your local authority or a licensed electrician.

• Look for: GFCI with self-test features, a matching amperage (15A or 20A) to your circuit, and tamper-resistant shutters for added safety.
• Maintenance: Testing with the built-in buttons regularly can help verify functionality.
• Shopping tip: Filter by features like GFCI, tamper-resistant, and color to match your space.

If you’re unsure about wiring or code, professional installation is a practical route.

The main difference is how much current the circuit is designed to carry. A 15A outlet is common for general rooms, while a 20A outlet is often used on heavier-duty circuits, such as some kitchens, workshops, or garages.

• Fit to the circuit: Match the outlet to the breaker and wire size already installed.
• Visual cue: 20A outlets typically have a T-shaped slot to accept 20A plugs.
• Don’t upsize casually: Replacing a 15A outlet with 20A without the proper 20A-rated circuit isn’t advisable.

When in doubt, check your panel labeling or consult a licensed electrician. Choosing the correct amperage can help support safe, reliable performance.

Tamper-resistant (TR) outlets include internal shutters that stay closed unless a proper plug is inserted into both slots at the same time. This design helps reduce the risk of foreign objects being pushed into live parts—useful anywhere kids might explore.

• Everyday usability: Standard plugs insert normally when aligned.
• Broad coverage: Many building codes require TR outlets in new residential construction.
• Where to use: Bedrooms, living rooms, play areas, and entryways are common choices.
• Note: TR outlets support safety but aren’t a substitute for supervision.

When shopping, look for "tamper-resistant" in the features. You can pair TR with other needs too, like GFCI or built-in USB charging.

Pick based on how you power and protect your devices:

• USB outlet (in-wall): Great for clean installs and everyday charging without bulk adapters. It usually replaces an existing outlet and adds USB-A/USB-C ports.
• Surge protector: Better when you need multiple outlets and protection against certain power surges. Some versions add USB ports and status indicators.
• Wall taps/extenders: Handy for quick expansion, with or without surge protection. Non-surge models can be useful in places that restrict surge devices.

Consider location (desk, kitchen, bedside), number of devices, and whether surge protection is important. If hardwiring isn’t your thing, a plug-in solution may be more convenient.
