How to tell if a wire is polar?
For those unmarked wires, you can first try to identify the polarity by looking at physical characteristics like color or texture. If you still aren’t sure, test your wires with a digital multimeter.
Where can I find wiring diagrams for my car?
Every car follows its own color-coding system for wires. There is no standard or international system, so find the wiring diagram specific to your make and model in your owner manual. If you no longer have your manual, look for one in a library or online. Or, reach out to a mechanic at a local shop or dealership.
Is copper wire positive or negative?
Know that the copper wire is usually positive on a speaker wire. On a standard wire used for things like speakers and amps, the silver strand is the negative wire and the copper-colored strand is the positive wire. These wires are often held together by a clear casing, so they’re easy to determine the polarity of each side quickly.

What color wires are used in UK AC circuits?
US, AC: The US National Electrical Code only mandates white (or grey) for the neutral power conductor and bare copper, green, or green with yellow stripe for the protective ground. In principle any other colors except these may be used for the power conductors.
What color is the neutral power conductor?

What color is the protective ground?
The protective ground is green or green with yellow stripe. The neutral is white, the hot (live or active) single phase wires are black , and red in the case of a second active. Three-phase lines are red, black, and blue.
What color is the ground for DC power?
US DC power: The US National Electrical Code (for both AC and DC) mandates that the grounded neutral conductor of a power system be white or grey. The protective ground must be bare, green or green-yellow striped. Hot (active) wires may be any other colors except these.
