If following the National Electric Code (NEC) - most commonly used in USA there is no distinct limit to the number of outlets. You must calculate load in accordance with Article 220 and you must determine the largest motor load anticipated.

If the current on a 240-volt circuit is 20 amps, then it's supplying 4,800 watts.

If the current on a 120-volt circuit is 20 amps, then it's supplying 2,400 watts.

How many outlets are there?

Up to 12 on a 20 amp circuit. Up to 9 on a 15 amp circuit. But use common sense. If the circuit will be heavily loaded, as in a home office, then do not install that many.


How many outlets are allowed on a 240 v branch circuit?

Branch circuit loading In Canada the CEC states that there shall be not more than 12 outlets on any 2-wire branch circuit. These outlets shall be considered to be rated at not less than 1 amp per outlet Where the connected load is known, the number of outlets shall be permitted to exceed 12, provided that the load current does not exceed 80% of the rating of the over current device protecting the circuit. For example on a 15 amp breaker, 15 x 80% = 12 amps, hence the standard of 12 outlets on any 2-wire branch circuit. On a 20 amp breaker, 20 x 80% = 16 amps. So from a 20 amp breaker this allows 16 outlets on a 2-wire branch circuit as long as the outlets are not considered to be rated at less than 1 amp per outlet. The definition of an outlet is a point in the wiring installation at which current is taken to supply utilization equipment. What this means is that if a light switch and a fixture outlet were on the same 2-wire branch circuit they would be subtracted from the maximum count of 12 receptacle outlets on the circuit which would leave 10. If the light fixture draws 3 amps plus the switch outlet, then the total circuit outlet count would be reduced to 8 receptacle outlets (12 -- 3 -- 1 = 8). On a standard specification home most electricians will wire one circuit per room, the outlet count usually never reaches the maximum of 12 outlets.


How many outlets can you have on a gfi breaker?

Depends on the breaker. If the load at the outlets is unknown then the standard rules of 80% apply. You can only load a circuit 80% of it's maximum value. For instance, if you're connecting your GFCI outlets to a 15 amp breaker you can only have a maximum of 12 outlets. If it's a 20 Amp breaker then you're allowed up to 16 outlets and so on. In the US, you are limited to 13 receptacles on a 20 amp circuit and 10 receptacles on a 15 amp circuit in commercial or industrial installations. Any or all of these can be gfci-protected. You can install one gfci, the first one from the panel, and protect any or all the others from that one.


How many 1.2 amp lights can a 20 amp breaker hold?

No more than 13 maximum on a 20 amp circuit.


How many outlets can you have on one circuit?

Depends on what the outlets are controlling, size of the wire, and size of the breaker.

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 is the number of plugs can a 15 amp circuit handle?

according to electrical code, a maximum on 12 outlets on a branch circuit unless the loads are known.


How many elec outlets can a GFCI detect?

7 on a 15 amp circuit and 9 on a 20 amp circuit.


How many recessed lights can you put on a 20 Amp circuit breaker?

If there is nothing else on the circuit then you could easily install 15. If there are outlets on the same circuit then try and keep the total of outlets and lights to a maximum of 15. But in reality the number of devices depends on how many amps each device pulls. Add up the amperage of the recessed lights you are going to install and then add any outlets and what may be plugged into them to get the number you can install. A 100 watt light bulb will draw about 1 amp. So you can easily have 15 on a 20 amp circuit.


What size circuit breaker do you need for kichen counter outlets?

Two 20 Amp circuits with the outlets staggered so a different circuit is on two adjacent outlets. Should be GFCI protected.

Can you control 10 outlets with one 20 amp GFCI outlet on one 20 amp circuit?

Yes. I know of no limits to how many regular receptacles (outlets) you can "piggy back" onto one GFCI receptacle. However, in commercial and industrial construction there are limits to how many receptacles can be placed on any one circuit. These limits in the United States and according to the NEC are: 10 receptacles on a 15 amp circuit and 13 receptacles on a 20 amp circuit.


How many outlets can be put on the 120 volt circuit if the outlets are rated at 120 va per outlet?

120 va on a 120 v socket means you can draw up to 1 amp from the socket. The number of outlets/sockets depends on the amp rating of the circuit. If it's 10 amps you can definitely have ten sockets and your local wiring regulations might allow more, on the basis that they won't all be used at once.
