Why does AC use three wires?
To power a device, current has to flow thru it. That means it has to go in one place and come out another, which requires two wires. The third wire of most outlets is a safety ground. It is not necessary to power a device, but can be useful to some devices.
Can you run AC and DC in the same conduit?
We have been asked a few times in the recent past as to whether we can run DC and AC cables run in the same conduit. The answer is No since the DC cables could induce a DC voltage onto the AC side. The AC sine wave should oscillate about the 0 volt axis i.e., the positive and negative cycles should be the same.
Can I run low voltage and high voltage in the same conduit?
It’s completely code compliant to run different voltages in the same conduit provided all conductors are rated for the highest voltage present. As stated above, run a couple of #14 THWNs, and you’ll be fine.
Can you use an AC adapter as a DC power supply?
With an ac adapter as a DC power supply and an adjustable voltage converter ( please see the previous posts) to be able to adjust the voltage up or down, you have an inexpensive and convenient way to power your circuit board projects and experiments.

Why are there 3 wires on a DC plug?
Remote voltage sense as tony suggests. And because some of these chargers are actually both barrel and center pin, making them have 3 conductors. The third conductor is typically a 1 Wire type data connection, and is used to signal what type of charger is being used. Dell and Lenovo use these extensively.
Can a DC Circuit be wired to an AC circuit?
Circuit breakers rated for AC won’t work for DC. Expect to pay more for DC breakers. On the other hand, fuses are mostly indifferent to AC or DC, or even differences in voltage. Older-style circuit boxes employing fuses that no longer meet Code for AC wiring will work fine for DC circuits.
What is the input voltage of a DC adapter?
V = An input Voltage of 19.5V. AC or DC – DC as indicated by the symbol. mAh/A – consumes 3.34A to 4.62A of current. Once you have this key data you are ready to start looking for an adapter.
