Different Types of Electrical Outlets in a House
It’s essential for safety reasons and to protect appliances from understanding the different types of electrical outlets in a house.
Even though electric outlets appear to function similarly, this isn’t the case. There are several outlets, each having its function and traits. Therefore, it’s essential for safety reasons and to protect appliances from understanding the different types of electrical outlets in a house.
Most common: 15-amp, 120-volt outlets
There are two versions of this type of electrical outlet in every American home. One has two connection slots, while the other has an extra vertical slot and ground pin. The latter is designed to prevent loose wiring from causing electric shocks when plugging in appliances.
This outlet’s low price makes replacing or installing one remarkably cheap. Nevertheless, they can be upgraded.
More power: 20-amp, 125-volt outlets
This electrical outlet allows the device to draw more power than the first type. Appliances that need extra electricity to function effectively should be plugged into these outlets instead of 15 amps, 120 volts. Homeowners can identify a 20-amp outlet by checking for a small horizontal slot along the vertical one.
Major power: 20-amp, 250-volt outlets
Most home appliances won’t need this much power, but air conditioners and larger electronic equipment will. Only this outlet is strong enough to provide the necessary power. Appliances such as washers and dryers, electric ranges, and refrigerators need even higher ratings, such as 30 amps or even 50 amps.
GFCI outlets
Ground Fault Circuit Interrupter (GFCI) outlets are usually in bathrooms, basements, and laundry areas. Others install them in outdoor areas. When the outlet detects a power surge, it instantly interrupts the circuit to keep anyone using the electronic device.
This phenomenon can occur if a device like a hairdryer falls onto a bathtub full of water.
Arc Fault Circuit Interrupter (AFCI) outlets, on the other hand, protect users from loose contact points that allow electricity to arc. Arcing results in sparks or electrical buzzing sounds, creating heat as well. AFCI outlets will deactivate when something damages the wire enough to cause severe arcing.
Many homeowners have AFCI outlets in bedrooms, kitchens, and other areas where GFCI outlets are installed. Both types prevent dangerous accidents from escalating to uncontrolled levels.
USB outlets
Some buildings have electric outlets possessing built-in USB ports. Anyone whose smartphone or tablet needs charging can quickly insert a cable and replenish the device’s battery. A charging brick isn’t necessary, as the outlet directly supplies the electricity. USB outlets often share a plate with standard outlets.
Know the difference
Many other outlet types are uncovered, most of them being specialized variants used for various applications. If one needs help identifying an electrical outlet or a significant appliance that needs a dedicated circuit, it’s best to contact a trustworthy electrician. Electricity is no place to practice DIY skills.
