An electrical outlet is a point in a building’s electrical system where devices can be plugged in to receive power. It’s also called a receptacle.
Key Facts:
- Voltage & Current:
- In the U.S.: Typically 120V, 15–20A
- In Europe & many other countries: 220–240V
- Types:
- Standard outlets – for everyday appliances (lamps, chargers)
- GFCI outlets – Ground Fault Circuit Interrupters, used in wet areas like bathrooms/kitchens for safety
- USB outlets – built-in USB ports for charging devices directly
- Structure:
- Live (hot) slot – supplies current
- Neutral slot – completes the circuit
- Ground slot – safety, directs electricity away if there’s a fault
Safety Tips:
- Never insert objects other than plugs.
- Avoid overloading with too many high-power devices.
- Use GFCI outlets in wet areas to prevent shocks.
- Keep outlets away from water and ensure child safety covers if needed.
