Outside porch lamp has no box just two wires coming in black wires are tied and don't connect to fixture just the white wires what is going on here?

It sounds like the black wires may be hot wires coming from the power source and the white wires could be neutral wires. The black wires are typically connected to the fixture's black wires. If the black wires aren't connected and capped off, the fixture won't receive power. It's important to properly connect all wires to ensure the fixture functions safely.


What polarities red wires and black wires indicates in case of dc measurement?

In DC measurements, the red wire typically indicates the positive polarity (+) while the black wire indicates the negative polarity (-). It's important to connect the red wire to the positive terminal and the black wire to the negative terminal when taking measurements to ensure accuracy and avoid damaging the equipment.


Have a red white black wires for a dryer plug what wires are hot ones?

In a typical dryer plug, the two hot wires are usually the red and black wires. The white wire is typically the neutral wire and the green or bare wire is the ground wire. Always consult the manufacturer's instructions to be sure.


What are black with green and black with white wires mean?

Black wires are typically used for power supply, while green wires are commonly used for grounding. White wires are usually neutral wires in electrical systems. It is important to follow proper wiring color codes to ensure correct connections and safe operation of electrical devices.


Connecting black and white wires to 306 angel eyes?

To connect black and white wires to 306 angel eyes, first identify the positive and negative wires on the angel eyes. Typically, the white wire is positive (+) and the black wire is negative (-). Connect the black wire from the angel eyes to the ground or negative terminal of the power source, and connect the white wire to the positive terminal. This will provide power to the angel eyes for illumination.

How do you fix reversed polarity in a home inspection?

reversed polarity in an electric circuit, means whoever was doing the wiring had no knowledge of wiring. reversed polarity means that wires ( mostly on outlets) are incorrect. the black wire goes on the gold screw, the white goes on the silver one & the bare wire goes on the green screw. most home centers have a library of how to books. they average around $20.00 each.

How do you wire 220V with 2 black 1 white wire?

Your black wires are your hot wires. The white is your neutral or common. It would be best to run an equipment ground (green wire) too.


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.
