The number of devices depends on how many amps each device pulls. If 10 devices pull 2amps a piece then that is your entire 20amps. If your breaker trips then you know you've exceeded the amperage for that circuit.

∙ 10y agoDepends on the load, or rather the current draw of the individual devices. If the total current draw is less than 20 amps all is fine. If the total current draw is more than 20 amps, then the breaker will trip.

There is no limit to the number of receptacles permitted by the NEC on a 20 amp circuit in a single family home.
Not sure if your trying to add receptacles or simply trying to gauge if your overloading a circuit.
Here is good rule of thumb: calculate VA.
VA is simply volts multiplied by amps and commonly known as a watt. A 20 amp breaker at 120 volts provides 2400 VA/Watts.
NEC 220(b)(8) attempts to clarify and defines 180 VA per duplex in commercial and industrial applications. 2400 VA from 20 amp breaker provides 13 receptacles. (120 volts times 20 amps provides 2400 VA) and (2400 VA / 180 VA = 13)
If you trying to calculate the number of amps your using simply add the VA of all devices on the breaker. If you are not given watts then use amps to find watts. VA = volts x amps. Volts are already known at 120.

Can a circuit breaker be tripped by using 20 amp sockets instead of 15 amp sockets?
A circuit breaker protects the wires that the devices are connected to. If the devices that are connected to the circuit are 20 amps the wire size should be #12 wire fed from a 20 amp breaker. This breaker should not trip unless the circuit is overloaded or a fault occurs on the circuit. If the devices that are connected to the circuit are15 amps the wire size should be #14 wire fed from a15 amp breaker. This breaker should not trip unless the circuit is overloaded or a fault occurs on the circuit. Putting 20 amp sockets on this 15 amp circuit will work but the circuit is limited to the amount of load that can be plugged in. You will not get the full capacity of the 20 socket because the breaker will trip at 15 amps.
Can you use a 20 amp fuse and wire rated for it in a 15 amp outlet?
You can use the wire rated for 20 amps on a 15 amp receptacle but you can not use a 20 amp fuse on any device rated at 15 amps. This is a tricky part of the code about receptacle outlets, You can use a 15 amp duplex outlet on a 20 amp circuit. (duplex outlet two devices can plug in) If it is a single outlet then the outlet must be rated 20 amp. NEC table210.21(B)(3). ============ A 15 amp duplex receptacle can be wired to a 20 amp rated circuit. This means the breaker OR fuse protecting the circuit can be rated 20 amps if the wire is also rated at 20 amps (12 AWG). --Sparkfighter
2.5mm electrical wire can use how many amp?
20
How many elec outlets can a GFCI detect?
7 on a 15 amp circuit and 9 on a 20 amp circuit.
How many 20 amp circuits can you run on a 50 amp service?
In the United States, there isn't a hard limit on how many 20 amp circuits that can be run on a 50 amp supply. This is because in most cases, especially in homes, we don't load most circuits with more than an amp or 2, even when they are protected by a 20 amp breaker. From a practical perspective you probably have a limited number of slots for breakers in your service or supply panel.
What size wire is needed to run a 50' 20 amp curcuit?
12 gauge or bigger.
Can your 30 amp generator pull a double 20 amp circuit?
When the term "double 20 amp circuit" is used, the presumption is that, it is 20 amps at 240 volts. If your generator has the breaker built in then, yes, you have the capacity to run 240 volt devices from your generator.
How many 1.2 amp lights can a 20 amp breaker hold?
No more than 13 maximum on a 20 amp circuit.
How many 5 amp TVs can be plugged into a open circuit?
You can plug in as many as you want but none of them will work. An "open" circuit is an electrical circuit which is not a complete circuit and therefore electricity will not flow through it. If you mean an unused circuit,which has no load on it, then the answer is 2 ea. 5 amp devices on a 15 amp circuit and 3 ea. 5 amp devices on a 20 amp circuit. The reason for this is that any circuit is not to be "loaded" more than 80% of the OCPD (circuit breaker amperage rating.
