In electrical home wiring that is wired correctly NO.
It doesn't connect to either. The red wire must connect to a red wire from the breaker box. If you only have black and white wires from the breaker box and the baseboard heater has a red wire something is wrong!
Remove the old single pole switch. Connect the green dimmer wire to the ground wire. Now connect the black dimmer wire to the black wire that is the hot wire (wire carrying the electrical current into the box). Connect the red dimmer wire to the other black wire.
Connect black to black, red to red, and white to green.
Connect the black wire to the incoming hot wire and the red wire to the out going load.
Connect black to black, red to red, white & green, to green.
Red is negavite some black
if you mean the red wire used for a ceiling fan you connect the red wire to the blue wire
The black and white (neutral) wires connect to an unswitched voltage supply. The red wire and the same white (neutral) wires connect to the load.
The brown will connect to the redblack wire and the blue to the white
Yes, in some circuit connections the red wire will connect to the black wires. Without more information as to how the circuit operates and what is trying to be done with the circuit, this is the only answer that can be given.
Two wires are hot and are usually Red and Black. Connect the white wire to neutral and green wire to ground.
You can't. You first figure out what the red and black do and why there is no white. Then you call an electrician to explain grounding/earthing wires and how to get a proper ground to the green wire before someone is electrocuted.
