The terms "socket" and "outlet" are often used interchangeably, but there are some differences:

• Outlet: In the U.S., "outlet" usually refers to the entire unit installed in the wall where you plug in appliances or devices. It can include standard electrical outlets, USB outlets, or specialty outlets like GFCI.
• Socket: "Socket" can refer more specifically to the part of the outlet where the plug fits in. In some regions, "socket" is the common term for what Americans call an "outlet."

When shopping, you'll mostly see "outlet" used for home electrical products.

Choosing between 15 amp and 20 amp outlets depends on your home's wiring and what you'll be plugging in:

• 15 amp outlets are standard in most living spaces and bedrooms. They're suitable for lights, TVs, and small appliances.
• 20 amp outlets are often used in kitchens, laundry rooms, or workshops where you might use higher-powered devices like microwaves or power tools.

Before upgrading, check your circuit breaker and wiring to make sure they support 20 amps. If you're unsure, it's a good idea to consult a licensed electrician for safety.

"Wall socket" is another way of saying "electrical outlet." It's the spot on your wall where you plug in things like lamps, chargers, or kitchen appliances. In the U.S., you'll often hear "outlet," while "socket" is more common in other countries. Both terms refer to the same basic thing—a connection point for electricity in your home or office.

The "2 6 12 rule" is a guideline for placing wall outlets in residential spaces:

• 2 feet: Outlets should be no more than 2 feet from any door opening.
• 6 feet: Outlets should be placed every 6 feet along a wall so cords can reach easily.
• 12 feet: No point along the floor line should be more than 12 feet from an outlet.

This rule helps make sure you have enough access to power without needing extension cords, supporting both convenience and safety.

GFCI (Ground Fault Circuit Interrupter) outlets are designed for areas where water might be present, like bathrooms, kitchens, garages, or outdoor spaces. They help reduce the risk of electrical shock by quickly cutting off power if a ground fault is detected. If you're installing or replacing outlets in these locations, local building codes often require GFCI protection. If you're unsure, it's a good idea to check with a qualified electrician or refer to your area's electrical codes for guidance.
