QA

Can you have AC and DC on the same line?

Usually applying similar voltage DC to an AC rated device or AC voltage to a DC rated device leads to magic smoke, flames, bad smells and/or worse. If Murphy cannot manage destruction then poor operation or no operation is common.

Can you power an AC device with DC? AC devices like your washing machine, dishwasher, refrigerator and fans can't work off DC. Your air conditioning maybe can if the description includes the word "inverter", otherwise no. These devices typically run on mains-connected AC motors. Wrong voltage or frequency, and they won't work.

Can AC and DC be grounded together?

Depending on the application, you can choose between a single ground point that ties all AC and DC voltages together, or separate grounds for the AC and DC voltages. In creating a common ground, you typically would connect the incoming AC voltage ground with the negative leg of the DC voltage.

Can 2 different circuits share a neutral?

What is a multiwire branch circuit? A multiwire branch circuit is a branch circuit with a shared neutral. This means there are two or more ungrounded (hot) phase or system conductors with a voltage between them and a shared neutral.

Can AC devices run on DC?

AC devices like your washing machine, dishwasher, refrigerator and fans can't work off DC. Your air conditioning maybe can if the description includes the word "inverter", otherwise no. These devices typically run on mains-connected AC motors. Wrong voltage or frequency, and they won't work.

Is AC and DC wire the same?

Both AC and DC describe types of current flow in a circuit. In direct current (DC), the electric charge (current) only flows in one direction. Electric charge in alternating current (AC), on the other hand, changes direction periodically.

Can AC and DC share the same circuit?

The Electrical Code prohibits AC and DC in the same box. You'll need two distribution boxes – one for AC and one for DC. Circuit breakers rated for AC won't work for DC.

Can AC and DC share the same conductor?

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 you plug an AC adapter into DC?

Each AC/DC power adapter is specifically designed to accept a certain AC input (usually the standard output from a 120 V AC outlet in your home) and convert it to a particular DC output. Likewise, each electronic device is specifically designed to accept a certain DC input.

Can you use AC to power DC?

Direct current can come from multiple sources, including batteries, solar cells, fuel cells, and some modified alternators. DC power can also be "made" from AC power by using a rectifier that converts AC to DC.

What happens if I connect AC to DC?

If we connect an AC supply to the DC devices and equipment: The positive and negative voltage will destroy (this is not always the case) some of electronic components such as transistors and electrolytic capacitors. In case of higher AC voltage, they may burn with blast and catch fire.

Remember: the input of the device should be the same as the output of the adapter. This includes polarity. If the device has a DC input of +12V / 5.4A, get an adapter with a DC output of +12V / 5.4A. If you have a universal adapter, make sure it has the proper current rating and choose the correct voltage and polarity.

Is AC ground and DC ground the same?

If a circuit is grounded through a capacitor it is referred to as AC-grounded because only AC signals can pass through the cap to ground, DC levels are blocked. Whereas if a circuit is such that DC current can flow to ground, such as through a resistor, then it is considered to be DC-grounded.

Can you mix AC and DC in same conduit?

The Electrical Code prohibits AC and DC in the same box. You'll need two distribution boxes – one for AC and one for DC. Circuit breakers rated for AC won't work for DC.

Can you share a neutral on different phases?

as long as the phase conductors are on different "phases" it's fine. Recent code requires them to be on a double pole breaker though. I do it as much as possible in houses. It's easier to pull one three wire for two circuits, than 2 separate two wires.

Can light switches share a neutral wire?

1 Answer. Show activity on this post. If not, no. If one circuit breaker turns off all three lights, then they are on the same circuit and you should be good to go.

Can I use DC for AC adapter?

An AC adapter is an external power supply that converts alternating current (AC) from a wall outlet to a direct current (DC) needed by an electronic device. Therefore, it is an AC/DC converter.

What will happen if DC supply is given to AC motor?

Detailed Solution. When AC supply is given to DC series motor: An AC supply will exert unidirectional torque because the direction of armature current and field current reverses at the same time and the direction of rotation will as it is.

Can AC wires be used for DC?

You can definitely use it. Please consider the resistance of the cable. The ohmic losses will reduce the 24 V supply voltage to a lower level at the remote end. If the resistance is 5 ohms for example, in total ohmic losses will be twice the 5 ohms multiplied by the DC current.

Can you run AC and DC cables together?

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 AC and DC currents be combined?

If we connect an AC supply to the DC devices and equipment: The positive and negative voltage will destroy (this is not always the case) some of electronic components such as transistors and electrolytic capacitors. In case of higher AC voltage, they may burn with blast and catch fire.

Can an AC and DC flow together?

No, since voltages don't flow. However, it is possible to have a DC and AC voltage superimposed on one another. This can cause DC and AC currents to flow, depending on the load that is connected to the voltage. Keep in mind that at any one time, there is only a single voltage.

What happens if you plug AC into DC?

Usually applying similar voltage DC to an AC rated device or AC voltage to a DC rated device leads to magic smoke, flames, bad smells and/or worse. If Murphy cannot manage destruction then poor operation or no operation is common.

How do you convert AC power to DC power?

If you want to convert AC to DC with a higher magnitude than the source, you can use a step-up transformer. Diodes: Allows electricity to flow into one direction when forward biased and blocks the flow in another direction. In this circuit, a bridge rectifier is built using four diodes.

Can you use AC and DC together?

The Electrical Code prohibits AC and DC in the same box. You'll need two distribution boxes – one for AC and one for DC. Circuit breakers rated for AC won't work for DC.
