It is the rating of how much current you can deliver to loads on a circuit. For example, if you had 10 outlets on 20 A service that is what you could run from the outlets on a circuit. This is a total capacity and not the capacity of each outlet on the circuit. If you plugged something into an outlet that drew 20 A you wouldn't be able to run anything on other outlets.

In a lighting circuit two 60 W incandescent bulbs draw one amp. Therefore, on a 15 A lighting circuit you could have a maximum of thirty 60 Watt bulbs. Usually you try and stay at about 80% of rating so practically you could have 24 bulbs.

A 15amp breaker is used with 14ga romex wire, designated

in homes for lighting. Common practice.

A 20amp breaker is used with 12ga romex wire ,designed for the outlets in a home.

Common practice.

Just wanted to add this to the great post above.

Can you tell the difference between a 15 or 20 amp circuit by the receptacle my box has 10 amps on the breakers and I know there is no such thing?

!0 amp breakers have not been used for quite some time . NEC made 15 amp the minimum requirement for 110/120 VAC circuit breakers a long time ago. If the breakers are only 10 amp, then those outlets can only carry 10 amps max.I would call an electrician. Your electrical service is terribly out of date and, in my opinion, inadequate and unsafe.


How do you know if you need a 20 amp gfi or 15 amp gfi?

The choice between a 20 amp GFCI and a 15 amp GFCI depends on the ampacity of the circuit you are protecting. A 20 amp GFCI can handle up to 20 amps of current and is typically used for circuits rated at 20 amps or less. A 15 amp GFCI is suitable for circuits rated up to 15 amps. It is important to match the GFCI to the ampacity of the circuit to ensure proper protection.


Can you plug a 15a 250v ac into a 30a 250v plug?

No, the amperage pin configurations are different between a 15 amp and a 30 amp plug.


What is the difference in performance between 13 amp and 15 amp miter saw?

Tough to tell. The extra amps may buy you some extra torque, but will cost you more to run. You are better off trying to read some reviews on-line since there are many other factors to consider.


What is the electrical formula to for calculating the number of 15 amp recepticles that can be install on a 15 amp circuit?

There isn't a formula, but the general rule is that you allow for 1 amp per outlet and you load the circuit to 80% of maximum. For a 15 Amp circuit you can have a maximum of 12 outlets.

What are the differences between a GFCI 15 amp and a GFCI 20 amp outlet?

The main difference between a GFCI 15 amp and a GFCI 20 amp outlet is the maximum amount of electrical current they can handle. The 20 amp outlet can handle higher power loads compared to the 15 amp outlet.

What are the differences between a 15 amp and a 20 amp GFCI?

The main difference between a 15 amp and a 20 amp GFCI is the amount of electrical current they can handle. A 15 amp GFCI is designed for circuits with a maximum capacity of 15 amps, while a 20 amp GFCI is designed for circuits with a maximum capacity of 20 amps. This means that a 20 amp GFCI can handle higher power loads than a 15 amp GFCI.


What are the differences between a 20 amp and a 15 amp GFCI outlet?

The main difference between a 20 amp and a 15 amp GFCI outlet is the amount of electrical current they can handle. A 20 amp outlet is designed to handle higher electrical loads than a 15 amp outlet, making it suitable for appliances and devices that require more power.

Can you plug a 2400 watt in a 15 amps?

No. A 120 volt 15 amp service will handle a maximum of 1,800 watts. Even a 20 amp service will only handle 2400 watts and that is at max load which you should never load on a 20 amp circuit. You will need a 30 amp 120 volt or 240 volt service for 2400 watts.
