What color is a black wire with a white stripe?
What about a black wire with white stripes and dashes? What Do Solid/Striped Lines on a Wire Indicate? The color of a wire refers to the polarity of that wire. White stripes show that the wire is the positive end. The unmarked wire is the negative. The answer to this question is not quite as straightforward as you think. The exact meaning behind each color will vary depending on the …
What color is the positive wire on a multi colored wire?
17/07/2006 · The lights and fan are independently operable. So the black wire is the fan hot, and the black with white stripe is the lighting hot. At least, that is the way my Hunter fans are coded; it is...
How to identify positive or negative wire markings on a stripe?
17/10/2005 · Black wire with white stripe = negative? Discussion in 'General Technical Questions and Answers' started by texham, Oct 15, 2005. Thread Status: Not open for further replies. Page 1 of 3 1 2 3 Next > texham QRZ Member. I purchased an Icom OPC-254L power cable. It is not red and black wire as I'd hoped, only black and black with a white stripe. If I remember right, the …
How do I connect a multicolor strip to a black and white?
Why are wire markings color coded?
Wire markings, especially for electronic equipment, are typically color coded to designate the positive and negative polarity. It is important to connect the wires so the positive wire is attached to the positive terminals on each end of the connection and negative to negative. Crossing the wires reverses the polarity of audio signals in stereo ...
Why does crossing wires cause short circuits?
Crossing the wires reverses the polarity of audio signals in stereo components such as loudspeakers and may cause a short circuit. If your equipment uses a black-and-white stripe with a connector on each end, just remember a simple rule to connect them correctly every time. Advertisement.
What to do if your test probes won't fit?
If your test probes won't fit then you use short pieces of wire to stick into the connector. Then touch the probes to the wires. You were VERY lucky that you did not damage the equipment. Most equipment uses a reverse polarity diode across the input to short out the input voltage if the input polarity is reversed.
How many volts dropped in a diode?
The drawback to this type of protection is that there is an average of around 0.7 volts dropped in the diode no matter what the current. Also, the diode has to be capable of handling the maximum current that is going to be drawn by the unit plus some safety margin. That is why most units use the reverse polarity diode.
Can a diode short a power supply?
First, the diode opens and as Glen said, the protection is gone and the rig gets the reversed polarity. Second, the diode can short and nuke your power supply. Or it can short and burn the house down if you're using something like a car battery for power. Word to the wise, use a fuse, no matter what.
What is reverse polarity protection?
The reverse polarity protection diode is INTENDED to pop the power line fuse in the event of the power being applied backwards. If you have no fuse in the power line - and lots of otherwise bright hams don't - a few things can go very wrong. First, the diode opens and as Glen said, the protection is gone and the rig gets the reversed polarity. Second, the diode can short and nuke your power supply. Or it can short and burn the house down if you're using something like a car battery for power.
