Your question is unanswerable because we have no idea what you're connecting. Without further information as to what these wires are for I would say leave the wires to a professional.
Assuming the wires are the correct gauge for application and breaker you use black and white wires as hot. Put red electrical tape on each end of white wire and connect red and black to the breaker output and bare wire to ground lug in panel. At receptacle connect black and red to hot contacts and bare wire to ground lug.
There is 220 volts between the two poles. If you are running 2 wires (black and white) + ground then you hook black to one pole and white to the other. Put red or black electric tape on each end of the white wire and wrap around wire for 3 inches or so next to the connection so the next person will be able to see that the wire is hot and not a neutral.
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.
The neutral wire and power wire are never connected together.
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.
The red wire typically connects to the black wire.
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.
The white wire is typically used to connect an outlet.
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.
To connect red and white thermostat wires for optimal functionality, you should attach the red wire to the R terminal and the white wire to the W terminal on the thermostat. This will ensure proper heating control in your HVAC system.
In electrical wiring, the brown wire typically represents the live (or hot) connection, while the blue wire is usually the neutral. If you're connecting these to red and white wires, the red wire often indicates a live connection as well, and the white wire is commonly used for neutral in North American wiring. Therefore, the brown wire should connect to the red wire, and the blue wire should connect to the white wire. Always ensure to follow local electrical codes and standards for safety.
Normally red or black is the hot wire and green is the ground. However someone may have used the green wire as the neutral wire which is normally white. Just connect the black wire from the light to the red wire and the white wire from the light to the green wire and see if it works. If not you have to pull the wires out of the ceiling box and see how they wired it.
Connect the white wire from the European oven to the white wire in the US receptacle. Connect the black wire from the European oven to the black wire in the US receptacle. Connect the green wire from the European oven to the bare wire in the US receptacle. The green wire serves as the ground wire since you don't have a separate ground wire in the US receptacle.
You can connect the red wire from the USB cable to the red wire of the two-wire cable. The black wire from the USB cable can be connected to the black wire of the two-wire cable. As for the white and green wires from the USB cable, since the two-wire cable only has a red and black wire, you can leave the white and green wires unconnected as they are not needed in this case. Just make sure to insulate the unused wires properly to avoid any short circuits.
The 1964 VW Beetle ignition switch only has three wires. Connect the red wire to the positive post. Connect the black wire to the negative posts. Connect the white wire to the auxiliary post.
Connect to the circuit neutral wire which should also be white.
It seems like you are describing the Red, Black, White and Ground in your electric panel. There is 240 VAC between Black and Red and 120 VAC between Black and White and 120 VAC between Red and White. The electric panel has two busses that supply 120 VAC on alternating breakers in your panel. Essentially, the Red turns into "black" in the panel for all practical purposes. If you have a 240 VAC circuit it essentially takes up to two vertical positions in your electric panel.
