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 information
In 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.

Can a 20 amp circuit breaker operate two 15 amp receptacle?
It is perfectly acceptable to have (2) 120 volt 15 amp receptacles operated from a 120 volt 20 amp circuit breaker (as a general rule of thumb 11 receptacles are acceptable on a 20 amp circuit). The 15 amp rating of the receptacle is the maximum allowed amperage that should be hooked up to the receptacle at any one time. So in this case the limiting factor is the amount of current being drawn across both receptacles simultaneously should not exceed the 20 amp rating of the circuit breaker. In the United States the NEC code allows the use of a 20 amp circuit breaker to feed a branch circuit consisting of 15 amp receptacles. Generally you would not exceed 11 receptacles though as you will assume an average load of 1.5 amps per receptacle and trying to maintain about 80% max load.
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.
What is code for electric outlet height outdoors?
Outdoor receptacles shall be installed outdoors so as to be readily accessible from ground or grade level. All outdoor receptacles located within 6 feet of ground or grade level shall be protected by a GFCI (Ground Fault Circuit Interrupter of the class A type.
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).
How many recs can a 20 amp breaker handle?
The electrical code states you can load a breaker to 80% of its capacity. The electrical code also states that, for loading purposes, one receptacle can be treated as one amp. Therefore, by code, a 20 amp breaker can supply 16 receptacles. The NEC (National Electrical Code) used in the United States has no requirement on the number of receptacles on a 20 amp circuit in a residential setting. The circuit should only service 500 sq. ft. of the dwelling, so a room for example of say 20 feet by 25 feet would be 500 sq. ft. It would require one 20 amp circuit. This circuit could also be used for the lighting load in this room. This is the minimum requirement to meet code and not always the best wiring practice.
Where must GFCI receptacles be installed in residential garages?
All receptacles in a garage must be GFCI protected by code. Typically, the first receptacle in the circuit (location is irrelevant) must be a GFCI, then all others down stream in the circuit will be protected, and can be common receptacles.

Is 26 receptacles wired on one 15 amp breaker up to code or standard practice for residential 26 receptacles include 10 can lights 4 other lights 12 outlets?
NO! You are drastically in excess of electrical code requirement. A 15 amp circuit should not exceed eight total receptacles and/or lighting devices.

Can you wire lighting fictures to receptical circuits?
Yes as long as you stay within your local code. Usually a combination of lights and receptacles cannot exceed ten total. Do not wire any light to a circuit that requires a dedicated circuit, such as a refrigerator, dishwasher, etc.

Are child proof receptacles required in the new national electrical code?
Yes, they are required by the national electric code.
How many receptacales on 20 amp circuit?
Answer for USA and Canada power supply service. Presuming a "15 amp circuit" is meant as a 120 volt system with a 15 amp single pole breaker with #14 awg wire, then: Per the National Electric Code, a breaker can only be loaded to 80% of rating. Thus, a 15 amp breaker can only feed a 12 amp max load. If the loads that will be plugged into the receptacles are unknown, then 180 watts shall be used for each duplex receptacle. Maximum load allowed on the breaker is 120 x 12 = 1440 watts. Maximum receptacles allowed on circuit is 1440 / 180 = 8. Still, read the NEC or other required codes depending on the installation location and connected equipment. In Canada, 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.
Is it within code to hard wire a fluorescant light fixture into a 20 amp branch circuit that is now designated for general use utility receptacles?
It is not good practice in new wiring, but done all the time as part of a retrofit. Use 12 AWG wiring and make sure the circuit is not overloaded.
When is double parking allowed?
Double parking is almost never allowed, except in some circumstances when signs posted specifically allow it for short periods. Even a delivery driver that does it all the time does not make it legal. It may be allowed in some emergencies as outlined in the State Vehicle Code in your state. Do an internet search for the vehicle code in your state
