Having done this for many years, the best answer I can give you is: A hot wire can be any color. I say this not only because in the U.S., hot wires are allowed to be any color except green, white, or grey; But also because you never know what the person before you did. Sometimes they have even used green, white, or grey as a hot wire (illegally). Not only this, but since there doesn't seem to be any standard, a piece of equipment may be using just about any color as well as a hot. Your best bet for equipment is to find the wiring diagram, and for a circuit coming from a panelboard, to use a meter to determine what is what.
The gold terminal
green
red
The brass screw is for the hot connection, usually the black wire.; sometimes a red one. The silver colored screw is for the white wire or neutral. If there is a green screw, it's for the ground, usually a bare wire but may also be green.
White is the neutral wire. Black is hot, green is ground.
The gold terminal
You can check for an instruction sheet at the manufacturer's website, but most tachs have a black wire for ground, a red wire that is hot, a white wire that is hot, and a green wire that goes to the negative or tach terminal of the coil.
The positive wire is the 15 terminal and the wire is BK, Black, The 1 terminal is GR, Green
green
On a 98 Pontiac Sunfire, the red color of wire goes on the terminal marked "B" on the starter. This terminal is located close to the battery of the vehicle.
green wire is gr gray wire is neutra
your an idiot. what color is the negative wire for everything. BLACK!!!AnswerI think it is the Red one. Red is the color code for the positive terminal (also for your battery tender). Black or green indicates the negative terminal..
I would wire them using a common relay and a ground switched circuit i.e. Terminal #30 Hot Terminal #87 Load Terminal #85 Hot Terminal #86 Switched to Ground
because you forgot to put lube on it
An L5-30P is a two pole three wire grounding 30 amp, 125 volt plug . The neutral wire is connected to the W terminal, the ground wire to the G terminal and the hot wire to the only terminal that is left. The small blade/slot is neutral (white), the larger blade/slot is hot (black) and the notched blade/slot is ground (green).
(Note: this is US information. Other countries may use other color codes; consult an electrician in your local area.) Standard color coding for single-phase electrical wiring is that the neutral wire is white and the "hot" wire is some other color, usually but not always black. If the switch has instructions or a wiring diagram, follow that. If not, normally the white wire should be connected to the lighter (silver colored) terminals on the switch and the "hot" wire should be connected to the darker (brass colored) terminals. Some switches interrupt both electrical paths, and in those the terminal screws may be the same color and it doesn't matter which wire goes to which set of terminals (just don't cross them). If there are green terminal screws, those are for the green grounding wire.
red is usually the hot wire.
