In North America there shall be not more that 12 outlets on any 2 wire branch circuit. Such outlets shall be considered to be rated at not more that 1 amp per outlet. Where the connected load is known, the number of outlets may exceed 12 providing the load current does not exceed 80 % of the rating of the over current device protecting the circuit. ( This is not found in the National Electrical Code)

Generally each duplex outlet may count for 180VA. For a 15A circuit = 8 duplex max. For a 20A circuit = 10 max. This is in the Wiring Code, by the way. (This only applies to non-residential applications)
In some states the 3 amp per outlet is still being used. For this case, 6 outlets max. ( What States?)
In dwelling units there is no requirement for a maximum number of outlets on a circuit. The circuit could serve a single room of 500 sq. ft. and serve as many outlets you wanted including the lighting loads. (3 watts per sq. ft X 500 sq. ft.) This is the minimum requirement of the code and not necessarily good wiring practice.

As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.
Before you do any work yourself,
on electrical circuits, equipment or appliances,
always use a test meter to ensure the circuit is, in fact, de-energized.

∙ 13y agoIn any one circuit from a single breaker, you can have up to twelve outlets. You can protect them ALL from ground faults by using ONE GFI outlet. Install it as the "first" outlet in the cable run from the breaker panel, and feed the remainder (no more than eleven) of the run from the "out" side of it. They are designed to work this way. Take a look at the receptacles on the outside of your house (if you have more than one). Only one is a GFI type. The other is fed from it and is protected from ground fault.

In The USA How many outlets can be hooked up on a 20 amp circuit?
Rule of thumb is about 8 unless it is a dedicated circuit. The NEC has no requirements on the number of receptacles that can be on a circuit in a residential setting. The circuit should be layed out to only cover 500 sq. feet. A single room of 500 sq. feet, you could put as many receptacle as you want on one circuit.
Does the NEC code allow multiple 20A receptacles on a 20A circuit Put another way does a 20A receptacle with T shaped neutral slots imply that no other outlets are that circuit?
The National Electrical Code (US) allows up to thirteen 20 amp receptacles on a 20 amp circuit. 120V x 20A = 2400 VA each duplex receptacle is calculated at 180 VA 2400 / 180 = 13.3333 receptacles, since you can't put a third of a receptacle in, you have to round down to 13.
How many 15 amp receptacles can you put on a 15 amp breaker?
The NEC does not limit the receptacles in a residents. Industrial it is limited to 180 watts each.
What is the formula to figure out how many plugs and lights you can put on a circuit?
This depends upon the circuit breaker capacity. You may never load a circuit to greater than 80% of it's capacity. So you may load up to 12 Amps on a 15 Amp circuit, and, 16 Amps on a 20 Amp circuit. The National Electrical Code requires you to calculate each receptacle at 180 VA. If the circuit is 120 volts and 15 amps, you would have 1800 VA, divide by 180 VA per receptacle, equals 10 receptacles per circuit (minus the wattage of each luminaire or light fixture added to the circuit, before dividing by the 180 VA). If the circuit is 120 volts and 20 amps, you would have 2400 VA, divide by 180 VA per receptacle, equals 13.333 receptacles per circuit (round down to 13 receptacles),(minus the wattage of each luminaire or light fixture added to the circuit, before dividing by the 180 VA).
Does the code state how many receptacles are allowed on a 20 amp circuit?
Answer for USA, Canada and countries running a 60 Hz supply service.Allow for 1 amp per receptacle and then load the circuit to 80% of maximum.In the US and in every building except homes, code limits you to 13 receptacles per 20 amp circuit. In a home there is no limit because it is assumed that even if you put a receptacle on every stud, you couldn't possibly use them all.Further informationIn the United States in non-dwellings a circuit is limited to the number of receptacles a circuit can handle, calculating 180watts per duplex. This places a 13 receptacle limit on 20 amp / 120v circuits and a 10 receptacle limit on 15 amp / 120v circuits.In dwellings there is no limit on the number of receptacles that may be placed on one circuit since it is highly improbable that you could overload a residential circuit under normal circumstances.In dwelling kitchens, while there is still no limit in the number of receptacles, there is a requirement that counter tops be served by AT LEAST 2 SMALL APPLIANCE CIRCUITS RATED 20 AMPS.As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.Before you do any work yourself,on electrical circuits, equipment or appliances,always use a test meter to ensure the circuit is, in fact, de-energized.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.

Why put a multiplexer at the end of a circuit?
Multiplexers are used to transfer many signals over one line, and several control lines. You put it at the end of a circuit if you plan to send the output from that circuit to another circuit, so you use the least lines possible.

how many lights can go on one circuit?
You can find out more information on how many new fixtures can be put in a circuit by going to a home improvement store such as Lowe's or Home Depot or going to their direct website.
Can you terminate a 110 circuit and a 220 circuit in one box?
No, do not put terminate 2 different voltages in one box.
Where do you put a switch in a series circuit?
From the standpoint of basic functionality, you can put the switch anywhere. In a series circuit, there is only one path for current flow. If you open the switch, you interrupt that pathway and turn the circuit "off."There may be practical reasons to put the switch in one place or another, however. Sometimes it's put in a particular place in the circuit for manufacturing reasons. In other circuits, safety may dictate that you put the switch in a particular place: in a ground-referenced circuit for example, you may want to put the switch so that one side is at the ground point.
Where ammeter and voltmeter are put in circuit?
Place in parallel anywhere in the circuit. One lead goes to the hot, the other to the neutral.
Use the word ordinance in a sentence?
the city passed an ordinance that all garbage receptacles were to be put into the streets.
Where would you put an ammeter in a circuit?
in a series circuit or it will not work. Put it after the bulb
