In the US, house wire has the BLACK wire connected to the HOT phase of the service input. The WHITE wire is connected to the NEUTRAL of the service input.
Normally, both BLACK and WHITE wires are each connected to the 2 LOAD terminals.
It is also normal that the WHITE service wire is connected to the wider spade outlet receptacle. The BLACK wire would then be connected to the shorter or narrower outlet spade receptacle.
In wired screw lamp circuits, it is normal to wire the BLACK service wire to the center pad of the lamp socket and the WHITE wire to the screw shell of the socket.
In switch circuits, it is normal to wire the BLACK service wire to the switch. The HOT service circuit is then opened or closed by the switch.
Measuring voltage on your neutral means there is a break in neutral. If the neutral is broken you will measure voltage across the break or from the break to ground. Under this scenario you will measure the same voltage as you do on your hot wire and your load should not be working.
Measuring voltage on your neutral less than on your hot wire may mean you have a problem where your neutral is supposed to be bonded to ground in your main service panel. In this scenario your load may be working but you need to check the bonding connection.
What else can I help you with?
If both wires for a ceiling light fixture are black how do you tell which is the live wire and which is neutral?
If both wires are black, the one that connects to your white wire is the one that should have little writing on it. Black to the plain black wire, white to the wire with writing.
How do you wire touch light control ta-306a?
To wire the TA-306A touch light control, first ensure the power is off. Connect the black (hot) wire from the power source to the black wire on the control module. Then, connect the white (neutral) wire from the power source to the white wire on the control module, and finally, connect the light fixture's black wire to the output black wire on the module, while connecting its white wire to the output white wire. Once everything is securely connected, restore power and test the touch functionality.
Which side of the White neutral wire do you connect the Black power wire?
The neutral wire and power wire are never connected together.
My light fixture has writing on one wire but not the other?
If both wires are black then the one with the writing is the neutral wire. If the two wires are black and white then the white one is the neutral.
Should grooved wire be connected to white wire?
If you are referring to lamp cord type wire where both wires are brown then yes, connect the wire with the groves to the white neutral and the smooth wire to the black hot wire.
What is the red wire and what wire does it go with when there are three wires black red and white?
Red, white, and black are standard for a three-way switch (you have two switches that control the same fixture). You should also have a ground wire (copper, unsheathed). The black and red are negative, while the white is positive. It works pretty simply. When the switch is up, the black and white are linked, creating a circuit. When it is down, the red and white are linked. If both switches agree (both are red/white or both are black/white), then the circuit is completed and power flows.

Which side of the White neutral wire do you connect the Black power wire?
The neutral wire and power wire are never connected together.
Is the black and white wire both hot in this electrical circuit?
In an electrical circuit, the black wire is typically the hot wire, while the white wire is the neutral wire. Both wires can carry electricity, but the black wire is the one that carries the current to the device, while the white wire completes the circuit by returning the current to the source.
When wiring up a photocell where do the leads get connected?
Black Wire from photocel to hot wire(black) coming in red wire to light fixtures black wire. White wire to neutral wires all light and power source white.
How do you wire a doorbell transformer?
To wire a doorbell transformer, first turn off the power to the circuit. Connect the transformer's black wire to the power source's black wire, and the white wire to the white wire. Then, connect the transformer's low-voltage wires to the doorbell's wires. Finally, turn the power back on and test the doorbell.
What is the difference between a black wire and a white wire in electrical wiring?
The difference between a black wire and a white wire in electrical wiring is that the black wire is typically used as the hot wire to carry electrical current, while the white wire is usually used as the neutral wire to complete the circuit and return the current to the power source.
What are the differences between black and white wires in electrical wiring?
The black wire is typically used as the hot wire to carry electrical current, while the white wire is used as the neutral wire to complete the circuit. The black wire is connected to the power source, while the white wire is connected to the electrical load.
How do you wire a light and switch with the 2 wire old romex?
To wire a light and switch using 2-wire Romex, connect the black wire to the brass screw on the switch, the white wire to the light fixture, and the white wire to the silver screw on the switch. Make sure to cap the unused wire at both ends for safety. Be sure to turn off the power before starting and consult a professional if you are unsure.
How do you connect timer white and black house wire with red black and white wires?
House wire is "line" Black & White house goes to Black & White of Timer; the "load" (e.g. Pond Pump, etc.) is connected to the Red & White. Specifically, put all 3 whites together (nut or terminal); House (source)(line) Black to Timer Black; and "load" Black to Timer Red. The Red wire is the "Timed" (switched) hot wire.
How to wire a fluorescent light properly?
To wire a fluorescent light properly, first turn off the power to the circuit. Then, connect the black wire from the light fixture to the black wire from the power source, and the white wire from the fixture to the white wire from the power source. Finally, connect the ground wire from the fixture to the ground wire from the power source. Make sure all connections are secure and insulated before turning the power back on.
