How to wire 240 volt outlets and plugs

Rule of thumb: the hot wires connect to side of outlet.
Wire 240 Volt outlet
The hot wires connect to brass-colored screws located on side

Look for screw color on outlet

Brass (or black) for Hot, Silver for Neutral, Green for ground
Some outlets do not have color-coded screws.
Ignore Neutral screw if no neutral wire available

Hot wires can be Black-Red or Black-White

Rule of thumb: the hot wires connect to side of outlet.

Brass screw (or black) => Hot wire
240 volt electric circuit has 2 hot wires.

Green screw => bare copper or green ground wire

Silver screw => Neutral

Review basic 120volt and 240volt

Image shows 120Volt line and 240volt line.
Both circuits have ground wire.
Each 120 and 240 require two wires to complete circuit.
120V requires 1 hot and 1 neutral
240V requires 2 hots

Some 240Volt lines have additional neutral wire. Neutral not necessary to complete 240Volt circuit.
Some 240Volt lines have white and black instead of red and black

How to test for 120volt or 240volt

Hot wires can be Black-Red or Black-White
How do you know if the wire carries 120V or 240V?

Tape tester leads to wood sticks, and stand on dry wood boards.
Never stand on outdoor ground soil, or touch or lean into metal.
Put down dry boards.
Separate wires for testing.
Test each wire to bare ground wire. If both wires test for power to ground, the circuit is probably 240Volt.
Use multi-meter to confirm exact voltage.

10-3 wire
240Volt has 2 Hot wires.
Hot wires can be Black-Red or Black-White
Test each wire to bare ground. If tester shows power then wire is Hot
Neutral not required for 240V
240 volt breakers

Code says: Use connected/ double-pole breaker

Against code: Use 2 single breakers to supply 240 volt, unless the switches are connected and rated for same amps


Tandem breakers
Larger image

Install Tandem breakers

This panel has several tandem breakers
Each tandem fits over one busbar, and pulls double duty from each busbar.
Do not expect breaker panel busbars to last as long under double load.

You cannot draw 240 volt off of one tandem breaker..
But if two tandem breakers are side-by-side, then 240 Volt is possible.
For 240Volt, select the inside terminals... one from each tandem breaker.
Connect 240V wire to these two terminals.
To meet code, notice there is a connector bar (color reddish) that physically joins the two switches

Neutral is not needed for 240volt electric circuit


Neutral wire is usually NOT present in 240V circuit


Add black tape if white wire carries voltage

Calculate correct wire and breaker

Electrical calculation
1) Each 240Volt outlet sold at Hardware or Home Center will have amp rating.
For example some will be rated for 40 amps, and others for 50 amps etc.

2) Each appliance will have rating-plate located on side of appliance or inside door of oven, or back of dryer.

3) Formula: Volts x amps = watts.
Watts divided by volts = amps
Volts= 240Volts

4) Example: Double-oven wattage = 7000 watts.
7000 watts divided by 240Volts = 29.16 amps.

5) Figure breaker and wire size for double-oven:
Safe maximum for 30 amp breaker is 24 amps. So double-oven needs 40 amp breaker.
Use 8 gauge wire for 40 amp breaker.

Electrical formulas

Typical Household wire ratings

14 ga wire ++  rated for 120 Volts x 15 Amp breaker  = 1800 Watts x 80% = 1440 Watts

12 ga wire ++ rated for 120 Volts x 20 Amp breaker = 2400 Watts x 80% = 1920 Watts

10 ga wire ++ rated for 240 Volts x 30 Amp breaker = 7200 Watts x 80% = 5760 Watts

Getting 120 Volt from 240 Volt / possible if neutral wire is present

Illustration shows how to draw 120V from 240Volt line.
Only possible by code if 240Volt line has neutral wire.
These connections must be put inside enclosed box with cover.

Connect 12 gauge wire to 10 gauge wire.
Illustration shows smaller 12 gauge wire connected to larger 10 gauge wire.

10 gauge wire is protected by 30 amp breaker
The amp draw on 30 amp breaker is too large for 12 gauge wire.
12 gauge wire should have 20 amp breaker.

Use busman fuseholder with 20 amp fuse.
Fuse will protect entire length of 12 gauge wire.
Connect fuse to Hot wire.
Not necessary to put fuse on Neutral

If the 12 gauge wire was wired for 240V, then fuse is necessary for both hot wires.

120-240 volt generator
Image shows electro magnet on inside and coils on outside.
Small generators, magnets can be on outside and coil on inside.

At some level of power generation, you must have electromagnet.
But to to start the generator, you need get electricity for the electromagnet. To solve problem, they use progressively smaller generators until you get electricity using simple magnet and not electromagnet

120-240 volt generator

120-240 volt generator has 3 coils. A center coil that rotates. Two outer coils that sit 180 across from each other.
The center coil is electromagnet with North and South poles that rotates 60 times per second.
Each time the center coil passes Coil 1, it creates a pulse of electricity on Line 1.
Electricity is the flow of electrons across the surface of a conductor. Wire is one type of conductor.
Each time the North pole of center magnet passes Coil 1, the flow of electrons on Line 1 goes one direction. Then when the South pole of magnet passes Coil 1, the flow of electrons on Line 1 reverses and goes the other direction. This is called AC or alternating current. Up and down the electrons continually move on Line 1.
The voltage on Line 1 rises and falls as the magnet passes and the electrons slow down, stop and then reverse direction. When the electrons come to a stop the voltage is zero. And then the electrons reverse direction and voltage goes up.
At two points in each rotation cycle, the voltage drops down to zero, and then the voltage goes up again. Up and down the voltage rises and falls.. However the average voltage is above 0, and the generator rotates so quickly that the up-and-down voltage is not seen... and Line 1 tests120 volt to ground at all times. Line 2 also tests 120 volt to ground at all times. Testing Line 1 to Line 2 shows 240 volt potential.
Neutral wire carries no voltage. Grounding for the generator is supplied by connection to the ground busbar located in main breaker box, or by installing a ground rod and making a ground connection. Grounds and Neutrals are separate, but must be bonded (connected) together.

Coil 1 and Coil 2 are out of phase with each other, so Coil 1 and Coil 2 produce a reverse flow of electrons from each other. When electrons on Line 1 are flowing away from Coil 1 toward the house, at the same time, electrons on Line 2 are flowing toward Coil 2 and toward the generator.

Generator must have a balanced Load. What that means is that Line 1 and Line 2 must supply the amount of wattage as each other. So if you have 100 watt bulb connected to Line 1, then you need 100 watt bulb connected to Line 2.
You cannot run 1000 watts on Line 1 and 0 watts on Line 2, or the generator will overheat.
Calculate the wattage of each circuit by looking at appliance labels, and using the basic formula Volts x Amps = Watts.
Balanced loads apply only to the 120 volt circuits. When connecting 240 volt, the load is aromatically balanced, because the same wattage is pulled from each Line.
If 120/240V generator is rated for 5000 watts, then Line 1 carries 2500 watts and Line 2 carries 2500 watts.

Example shows unusual case where 240Volt circuit has neutral and no ground wire.
240Volt circuit does not require ground wire, or neutral.
Both Neutral and ground wires join inside the breaker panel, and are essentially serving same function.
However, it is not code to complete 120Volt circuit using ground wire. So this example lets each outlet have 120volt capability.
Notice that X and Y are Hot, W is Neutral, and there is no G for ground.

Note on the corner hardware site that it says maximum load on 12 gauge wire is 20 amps. This is misleading.
Electricians use 80% rule.
True that 12 gauge wire connects to 20 amp breaker, but electricians apply 80% rule to calculate load rating for breakers and wires.
20 amp breaker x 80% = 16 amps safe maximum for 20 amp breaker.
30 amp breaker x 80% = 24 amps safe maximum for 30 amp breaker
