That also is the drive of our presence today, which will not just inform you of the top five differences between them but also unveil some of the most tricky of this topic for you.

15 Amp Vs 20 Amp Outlet: What Are They?

Where Are 15 Amp Outlets Required?

A 15 ampere (15 amp) outlet belongs to one of the best outstanding electric receptacles in the current market.

The root of this dissemination is that the outlet delivers its compatibility and user-friendliness in most household applications for small-scale in-home and personal uses. 

It powers up most electronic devices like lamps or TV, which don’t exceed 12-amp loads. Therefore, this kind of outlet is commonly set up in bedrooms and living rooms, with many gadgets calling for low power. 

Typically, the outlet appears on the market with two key kinds. The first type comes in a two-prong one, which includes a prime hole accompanying the primary hole shaped like a letter U. 

The other is a design with a triple-prong outlet, comprising two principal holes along with one prime shaped like a letter U.

Moreover, setting an electric circuit for this outlet just requires a 14 AWG gauge wire. 

Where Are 20 Amp Outlets Required?

The pattern of the option is almost similar to a 15-amperage outlet. Nevertheless, it isn’t hard for you to find there is a small slot between two parts of the outlet. The 20 amp receptacle bears a horizontal one with dual pins placed at the left-corner position of it, which is designed in the form of a T letter. 

The outlet is not as popular as the 15 amp ones due to its compatibility. The 20 amp type can just match with its appropriate receptacle and say no to any other ones. 

With the 20 amp version, we may choose devices with the same amp plug to link directly to a receptacle. The design is specifically engineered for devices with high-powered capacities, like washing machines, refrigerators, and so on. Thus, 20 amp outlets are commonly used in laundry areas and kitchens. 

In addition to the safety domain, the outlets usually appear on outdoor applications for powering sources.
