What is the standard amperage rating for household outlets in the United States?
The standard amperage rating for household outlets in the United States is 15 or 20 amps. This rating is determined by the National Electric Code (NEC) and is based on the type of circuit and the intended use of the outlet. Most household outlets are rated for 15 amps, but some heavier-duty outlets, such as those used in kitchens or laundry rooms, may be rated for 20 amps.
It’s worth noting that the amperage rating of an outlet is not the same as its wattage rating. While a 15-amp outlet can handle a maximum of 1800 watts (15 amps x 120 volts), it’s generally recommended to keep the total load on the circuit below 80% of its maximum capacity to avoid overheating and other safety issues. This means that a 15-amp outlet should not be loaded with more than 1440 watts (80% of 1800 watts).
How do I determine the amperage rating of an outlet in my home?
To determine the amperage rating of an outlet in your home, you can check the outlet itself or the circuit breaker or fuse that controls it. Most outlets have their amperage rating printed on the faceplate or on the outlet itself.
