Types of Appliance Outlets
Every home has a range of different types of electrical outlets.
Every home has a range of different types of electrical outlets. However, not all of them are created equal, and it’s important to know what each type is suitable for and when to use them. Here are the types of outlets a home can have and appliances they can support.
Two-prong 15A 120V outlets
The cheapest and most common type of outlet is a two-prong 15A 120-volt outlet. Unfortunately, these two-prong outlets lack grounding and are outdated and potentially unsafe. Therefore, they can only be found in older buildings today, and one should switch them out for safer alternatives.
Three-prong 15A 120V outlets
The newer version of the above-mentioned two-prong outlet has a third slot for grounding. Three-prong outlets comply with modern building codes, the most common type found in homes. However, the 15A 120V version is only suitable for less demanding household appliances. Kitchen countertop appliances like toasters, blenders, coffee makers, etc., are some examples.
20A 125V outlets
Appliances that require more power should be plugged into 20A 125-volt outlets. These outlets look similar to the previously mentioned three-prong 120-volt ones. However, a sideways T-shaped slot on the left will signal that this outlet is more powerful. These outlets stand their ground even when supporting appliances like refrigerators and washing machines.
20A 250V outlets
While most appliances will work well with 20A 125-volt outlets, a few highly demanding ones require a 20A 250-volt outlet. Most stoves, dryers, and air conditioners fall into this category. Hobbyists might also want to install these outlets in their home workshops for their tools. 20A 250V outlets also feature a T-shaped prong on the left side, but one can still differentiate them as they are typically circular.
GFCI outlets
GFCI (or ground fault circuit interrupter) outlets can be recognized by a “test” and “reset” button on their panel. These outlets provide extra protection in water-prone environments, often installed in bathrooms, kitchens, laundry rooms, and similar spaces. GFCI outlets automatically cut electricity when they sense a dangerous power surge (whether water-related or not), preventing electrical hazards and protecting the appliances. Dishwashers typically use this type of outlet.
AFCI outlets
AFCI (or arc-fault circuit interrupter) outlets are another crucial asset of every home. These outlets protect against electrical arcing (electricity jumping between connections) that creates a hazard by producing an immense amount of heat. Use AFCI outlets for appliances in sleeping areas.
Keeping appliances safe
You should only plug each appliance into a suitable electrical outlet to prevent malfunctioning and electrical hazards. Expensive appliances can also be equipped with surge protectors to steer clear of damage caused by electrical surges. Call qualified professionals to change a broken outlet for your safety rather than tackle it alone.
