The wire to use would be one that can handle the 3 amp capacity of the load. If the load is a long ways away increase the wire size. A #14 wire has the capacity to handle 15 amps.
Depends on how far you're running it and what voltage drop you can tolerate.
I would use 14 gauge, minimum. That will give less than 10% voltage drop on a copper pair running 50 feet.
What else can I help you with?
What wire gage should you use for 12V at 8FT length for 1.5A?
22 guage
How much power is used by a 35w bulb with 12v supply vs 110v supply?
it also depends on what meter you have, is it a KWH METER or a AH METER. IF ITS A KWH METER(KILO WATT HOUR) IT COUNTS IN WATTS (35w PER HOUR.)
Can you replace a 12v- 35w fog light bulb with a 12v-80w?
As long as they are the same volt you should be able to change the wattage, I am assuming this is not on a vehicle in which case you should always check the department for motor vehicles for regulations.

Can you wire a house with 12V?
Yes.
Is the wire going to the parking brake positive or ground Honda prelude 1994?
The wire should rest at 12V+ or zero but when the parking brake is on the wire goes 12V- .
Connect a 12v wire to an amplifier?
Ensure the amplifier is turned off. Connect the positive (+) terminal of the 12V wire to the amplifier's positive terminal and the negative (-) terminal of the 12V wire to the amplifier's negative terminal. Once connected securely, you can then power on the amplifier.
How do you power a 12v speaker bar?
take a 12v power cord splice the wire and reconnect
What if your car audio is not turning on and the audio fuse is still good what is the problem?
what is meant by "car audio"? an amplifier will not turn on if it is missing either ground, 12v or 12v accessory turn on. the respective wire colors will be large red wire for 12v battery source, large black wire for -12v ground battery or chassis, thin blue wire for accessory 12v turn on. these wires can be tested for 12v with a multi-meter or a simple test light. a car radio is basically the same wire design for power up, most radios will need 12v to the yellow wire, accessory 12v for the red wire and chassis ground for the black. test these wires the same way the amplifier is tested and repair any wires not functioning correctly. if this does not help, respond with more detailed accurate assessments of problem for further advise.
How do you wire a 12v 3 prong flasher?
To wire a 12V 3-prong flasher, connect the power wire from the flasher to the battery positive terminal, the ground wire to the vehicle chassis ground, and the output wire to the turn signal switch or indicator. Ensure the wiring is secure and use proper connectors to prevent any short circuits.
Which gauge wire is a 12v?
The gauge of wire that is 12 volt is 18, 14, and 16.
What wire does the illumination dimmer wire connect to?
12v switched source. such as headlight switch or dimmer on the dash.
