Typically the black wire is "hot", and the white wire is neutral. A 2 pole breaker is most commonly used for 240 V, and as such, you would typically use a 3 conductor wire, with black, red and white (+ ground). In a typical application, the black and red are used in the 2 pole breaker, and neutral is connected to the neutral bar in the breaker panel.

In this situation, the electrical code requires the white wire to be identifies as a current carrying conductor. This is done by wrapping black electrical tape around the white wire. This will let anyone that works on the circuit in the future that the conductor is a current carrying conductor.

How do you wire a GFCI if there are 2 black wires?
You will have to run new electrical wire or a single ground wire back to the panel (though the former is highly recommended). A GFCI outlet will cut off the circuit if it senses voltage leaking to ground. If there is no ground wire, it will not function.
What do you use a clamp meter for?
The clamp part is for measuring amps via induction. You set meter to amps and clamp around only a single wire. Device you are measuring must be operating. This means you couldn't clamp around a lamp cord to a table lamp since the current induced in each direction cancels out. You would have to separate the wires. An electrician would carry a short extension cord with the wires already separated. Most often a clamp meter is use to checks amps in a breaker panel on the black wire coming from the breaker.
How do you wire multilple power outlets and light?
Power into the first outlet and out to all other outlets, black to gold and white to silver screw, ground wires to ground screw. From the outlet closest to the light switch run power from that outlet up to the switch box. Run another wire from the switch box up to the light. In the switch box tie all the whites together under a wire nut and push them back into the box. Tie all the ground wires together and connect that to the ground screw on the switch. Connect the 2 black wires you have left to the 2 screws on the switch. Does not matter which if you only have power in and power out to the light.
Why will too many electric devices operating at one time often blow a fuse or trip a circuit breaker?
In a house, usually all the outlets in a room are on one breaker or fuse. Each thing plugged into those outlets consumes some electrical power. This is a number rated in Watts. In this case, the more Watts something consumes, the higher the current is (measured in Amps) in the wires that connect the outlets to the main power in the breaker box. The current in power circuit must be limited for safety reasons. The wires in the walls can only handle a certain amount of current safely. If too much current flows the wires can become extremely hot, possibly starting a fire.
Can you install two ground wires in the same raceway?
There should be no reason to install two ground wires in the same conduit. Code requires that only a single path should be required if it is to carry a fault current. This ground wire should be single and continuous from the device back to the distribution panel. It is the fault current that is carried on the ground wire that trips the breaker or fault protection device. Don't confuse grounding wires with bonding wires.
Is it safe to have two black wires two white wires and two ground wires on a single breaker?
Hopefully just the black wires are on the breaker. Two circuits on one breaker. Shouldn't be a problem. It would depend on how many outlets or lights were on the breaker in total. Even then, there is very little chance of something drawing current from every outlet at the same time. The only thing is you can't put two wires under one breaker (by code). You would have to wire nut them with a pig-tail then just put the one wire under the breaker.
Where does the red wire in a baseboard heater connect to the black or white wire in the wall?
In the heater you will have two wires. You should then have 2 supply wires from the panel, and 2 wires from the thermostat. The neutral (white) supply wire should go to one of the wires on the heater. The hot (black) supply wire should connect to one wire from the thermostat. The other wire from the thermostat will connect to the other wire from the heater.
Can a ceiling fan be installed with only the black and white wires?
Yes.
How do you wire duplex receptacle using14-3 wire Also with 14-2 wire The wires are already ran to 15 amp breakers and capped off. i would like to hook them up. Thank You?
Sort of confusing are you using 14-3 just for the receptacle with 14-2 to the breaker or the other way around. Either way doesn't matter since you only need 2 wires and a ground for the outlets. The 14-3 should have Red, Black, White and bare wires. 14-2 should have Black, White and bare. All you need are Black, White and Bare. Forget about the red one. Hook the two outlets together with short jumper wires about 6 inches long. Looking at the outlet with the ground facing down, the bare wire goes on the bottom green terminal. The white wire goes on the left side of the outlet. The black goes on the right side of the outlet. Take the 6 inch jumper wire and go from the left side of one outlet to the left side of the second outlet. White to white, black to black, bare to bare. Connect the wires coming from the breaker to the other terminals on one of the outlets. Power comes in to one outlet and then to the second. If the wires are capped in the breaker box, you only need to connect the Black White and bare ones. Do this with the power off.
How do you hook up new black white and green wires to 2 old white wires and 2 old black wires?
More information is needed as to what device you are connecting to what power supply. The only two identifiable wires are the white and green. In North America the white colour is used for the circuit's neutral and the green is used for grounding of devices.
How can you wire a normal 120V outlet out of a double pole circuit breaker?
well, the easy answer is, black wire to one pole of the breaker, white wire to the neutral bus with all the other white wires, bare wire to the ground bus with all the other bare (or green) wires. BUT the breaker must be 20 amps or less for residential outlets and you much match the wire size to the breaker, #14 for 15 amp breaker, #12 for a 20 amp breaker AND if there is only going to be one outlet, if it is a 20 amp circuit, the outlet has to be rated for 20 amps. Yes, but why would you want to? It is unclear to anybody else what you are doing and therefore a hazard. Do it right. Use a single pole breaker designed for 110V.
If the old block heater cord of a 1988 Honda CRX had two wires and the new end has 3 which colored wires connect the new connector to the old one?
Connect to two wires you have to the the spade connectors and forget the ground connector. The spade connector wires should be black and white. Black to gold and white to silver. If the wires coming from the heater happen to be red and white, then red goes to black. You could buy a simple lamp cord which has only tow wires.
Where does the blue wire go to the exhaust fan and light if house only has black and white wires?
The blue wire is the hot in this case. It is the hot for usually the fan and then either a red or black is the hot for the light. If there is a heating lamp usually that will be a yellow hot. If you have separate switches for them then then simply one wire for each black, other wise pigtail the black and the 2 wires coming from the unit together. Make sure that if you are using one switch for the fixture that the breaker is suited for the amperage.
How do you connect 15 A 250 v wires to the outlit the are four wires white black red and green from the wall and there are only three screws?
Be sure that those wires coming from the box are for a recepticle and not a light switch.
How many wires can be connected on to a 20 amp breaker in NH?
Code only allows one wire to be connected to a single pole breaker. Any additional circuitry has to be done in a junction box downstream from the breaker.
Christmas light are causing the 15amp circuit breaker to trip and Circuit Panel is full Can I upgrade to a twin circuit breaker without installing a subpanel?
Your only hope is that someone wired the box not to code and that there are two wires going into the offending breaker. If you can't separate wires you can't distribute the load.
How do you rewire a 220 volt receptacle to produce 110 volts?
A 220 volt receptacle is a receptacle which has 2 wires carrying 110 volts...it has two "hot" wires at 110 and a neutral or common leg which has no voltage. A 110 volt receptacle is a receptacle which has 1 wire which carries 110 volts and a common wire. The wiring in the USA is almost standardized now to where the two "hot" (carrying 110 volts) wires are colored black and red, and the common or neutral is white. To change a receptacle to 110 volts..you remove the red or black wire from the old receptacle and wire nut it off...leaving the other red or black to attach to the new receptacle (right side of receptacle usually, looking at it from the grounding hole on the receptacle ON THE BOTTOM). You then connect the white wire to the left side of the receptacle. This will provide only 110 volts now. If the wires are not black, red, and white..they may be black, black, and white. In most cases, the white wire is always the neutral or common wire. When in doubt, buy a voltmeter and check each wire to the metal box in the wall...the wires carrying the 110 volts will usually read 110 on the voltmeter (or 115, 118..etc). Good luck!
