How do you connect two lighting outlets controlled by a single pole switch?

Answer for USA, Canada and countries running a 60 Hz supply service.
A two wire cable must be brought to the switch box from the distribution panel source. This "hot" wire is connected to the top of the switch. Whatever you do, do NOT switch the neutrals. Connect the ground wire to the back of the box. This ground wire is connected to every box in the circuit installation. Run a two wire to the first lighting outlet. At the switch box connect the white wires together and the outgoing black to the bottom of the switch. At the first lighting outlet leave about 6 inches of wire hanging out of the box. From this box run another two wire cable to the second lighting outlet box. Remember to connect the ground wires. Back to the first lighting outlet box connect a short piece of wire to both the incoming and outgoing wires, this is known as a "pigtail connection" and it is this short piece of wire that connects to the fixture. Do this with both the black and white wires. These connections splices are pushed to the back of the box and the pigtails are the wires to connect to the fixture. These two lighting outlets are now wired so as the fixtures will be in parallel with each other. The voltage potential is applied to the bottom side of the switch when the switch is turned on and the fixtures that are connected in parallel will both turn on.
Another alternative is if you want to control a table lamp from a receptacle outlet. This is done by switching only half of each of the duplex receptacles. Remove the brass tabs between each of the sockets on the receptacle. Leave the (silver coloured) tab intact. Run a two wire cable to the switch and pigtail the black wire into two "hots". One will go to the top of the switch and the other will go directly to the split receptacle. From the switch box a three wire cable will be required to complete the circuit. The unswitched "hot" will connect to the brass screw on the bottom portion of the split receptacle and the switched "hot" will connect to the brass screw on the upper half of the split receptacle. The white wire will connect to the silver coloured screw on the receptacle. This is popular connection for branches circuits where lamps are the only lighting for a room.
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.

The maximum number of duplex outlets that can be served by a single 15 ampere 120V circuit is?
10 outlets as defined by the national electric code
How many 15 amps sockets can i connect in a single circuit?
Circuit loading In Canada the code rule is, 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.
What type of switch would be used to control a lighting load from one control point?
In this type of situation, where there is more than one lighting circuit, a lighting contactor would be used. These types of contactors can be obtained in four and five pole configurations. Make sure that the contactor is rated for lighting loads and not motor loads. A normal switch, single pole single throw, would be used to switch the contactors on and off. A single switch could then be used to control as many contactors as you need to operate the lighting circuits.If there is just one lighting circuit, the total circuit amperage must be known, then the switch would be sized to the amperage of the circuit.
Why would i need a 20-Amp Single-Pole Switch insted of a 15 Amp?
You would need a 20 amp switch when the load controlled by the switch can draw as much as 20 amps. If you have a 20 Amp breaker supplying the circuit then you need to size all switches and outlets on that circuit to 20 amps.

How can you connect single phase generator in three phase supply system in house lighting system?
First house lighting systems are single phase not three phase. To connect a generator to the house lighting system for emergency power, it would take an electrician to do the job properly. The biggest concern would be to isolate the rest of the service from the main distribution supply service and then isolate the rest of the distribution panel loads from the lighting loads.
Can dimmers control switched receptacles intended for plug in lamps?
You can wire a dimmer into any circuit. The issue is where you do it for a specific outlet. The dimmer would just have to connect to a single outlet and not all outlets on the same circuit. The issue is getting a dimmer that is compatible with the device you are dimming. Some lighting requires special dimmers.
How do you wire a single phase contactor controlled by a pir in a lighting circuit?
Relatively simple. There are two power contacts, you wire the two wires for the line you want to interrupt or connect to these contacts. this is for the simplest type, SPST, one set of contacts to switch a power line on when the control signal is on. There are more complicated contactors with multiple sets of contacts. There are two connections for the control circuit which are typically low voltage AC or DC. Connect these to the control signal, ie, the signal you will use to turn the contactor on or off.
