Two wires are needed for 220 volts.
To install a new fixture to replace the one that was removed reconnect the two hot wires together and then reconnect the two neutral wires together. Place the two wires from the new fixture to the corresponding wire colours that you just spliced together. This wiring should be down stream from the light switch. When the switch is turned on the new fixture should light. If this is not the scenario of your question then more information needs to be given.
The better quality tools all have 3 wires. You are looking at cheaper tools.
If you mean 2 bare copper wires those are the ground wires. Tie them together and then connect the light fixture ground wire which will be green or bare copper to those ground wires.
The two wires which connect the timer switch on a Century 87423 battery charger are the red and black wires. The red goes to the positive connector while the black goes to the negative connector.
a usb cable has four wires, two for power and two for communication.
what two wires are the iat from the maf sensor on a Mitsubishi eclipse gs
TWO wires
there are two wires
The two red wires on Halo projectors are the power source for the product. Splice the two red wires into the appropriate wire source on the engine bay.
Two.
two wires are subwoofer output negative and two wires are positive
It's called dual voice coils. There are two wires for bass and two wires for voice. It provides more quality. I, myself am looking to see which wires are negative and positive.
The magnetic forces between the two parallel wires are attractive, as the currents in the wires flow in opposite directions, creating magnetic fields that interact with each other. This interaction results in an attraction between the wires due to the magnetic forces.
im assuming your looking for hot wires on the coil. They should be two wires of the coil
Interesting question... what exactly are you working on? Do you have voltage on all 4 wires? Why do you need to "convert" it? Is it AC or DC? Are you trying to change the voltage? For simplicity's sake, lets say you have four wires with voltage on an AC circuit. Twist the wires into pairs with THE POWER OFF. Now you have two wires. Or cap two and use two. If its DC, then combine the two + wires and the two - wires. But honestly, this question is waaay too vague for me to really help you.
Your two hot wires go to the load side of your contractor and the two brown wires go to your capacitor
