Can you use two separate 120 volt circuits to make 240 volt power and run 30 amps through the circuit they are both wired with 12-2 wire?

Yes because the total load is only 18 amps. It would be more usual to allow three 9-amp circuits on a 20-amp breaker because the total current would probably not exceed 20 amps at any one time.

Your house is supplied with two "phases" of 120v, and they're on separate wires with a neutral in between. For ease of explanation, we'll call one hot wire the X wire and the other hot wire the Y wire. It's 120v between X and neutral, and 120v between Y and neutral. But if you connect the X wire and the Y wire to your item and forget about the neutral, you get 220v. (This is how a water heater is connected.)
If one 120v circuit is fed by the X wire and the other by the Y wire, and you use 10-2 wire (12-2 is for 20-amp service; you'll burn the house down running 30a through 12-gauge wire) and a 30-amp double-pole breaker, you'll have a perfectly good 30a 220v circuit. If both circuits are fed from X or both from Y, you won't get any voltage because there's no potential difference between the two hot lines.

To accomplish what you want will take three spaces. One for the 30 amp 120 volt and two spaces for the 30 amp 240 volt circuit.

What are dual electrical circuits?
Dual electrical circuits refer to a system or setup where there are two separate and independent electrical circuits operating in parallel. This is commonly used in residential and commercial buildings to provide redundancy and ensure reliable power supply. Each circuit functions independently, allowing for distribution of electrical load and minimizing the risk of total power loss in case of a failure in one circuit.
How is electricity distributed in houses in order to supply power to appliances?
Electricity get distributed in the household through electrical circuits. The circuits distribute voltage to receptacles, light and hard wired appliances. These circuits are fed from breakers that are in the distribution panel. The distribution panel is where the utility company's service supply terminates. The distribution panel is the central location where the household circuits originate.
Power and lighting loads are usually on separate feeder circuits to prevent?
Lighting flicker
Why power circuits and lighting circuits require a separate circuit breaker?
Utility outlets and lighting outlets should be separate so that when a utilization device plugged into an outlet trips the breaker or blows the fuse, you won't be left trying to find your way to safety in the dark. Light fixtures are much less likely to trip a breaker in ordinary use, but there are places you also want more than one lighting circuit for illumination.
What type of electrical current is used to transmit electricity to our homes and workplaces?
Both series and parallel circuits are used in the home. If the circuit is a dedicated circuit which means that there is only one device in the circuit, then it is a series circuit. All the rest will be classed as parallel circuits.
Why gate circuits are isolated from the main circuit?
Gate circuits should be isolated from the main power circuit to avoid any damage to the power circuit if gate is damaged.
What is the purposee of powersupply in the circuits?
the purpoes of powersupply in the circuit is to pass electricity through the circuits.the circuit created to serve the different purpose and the power supply complete the purpose of the circuit.
Are transistors polarised?
No it alternates the power from the circuit/circuits.
The layout and functioning of a nuclear power station to the three separate water circuits?
See the link below for a description and diagram of a PWR. This shows one water circuit, in designs with three circuits there are three separate steam raising units each in a separate circuit, each doing the same duty. There is also of course the secondary circuit which passes steam to the turbine and returns condensed water to the steam raising units

What are reciprocal circuit elements?
Reciprocal circuit elements are those elements/circuits in which power loss/gain is same at both nodes/ends.In these types of circuits we can check the circuit or connect it in any way.
What is the function of circuit breakers and fuses?
Protection. They shut off the power to protect the equipment circuits, the main circuits and people.
What is logic for ground in digital electronics?
In some types of electronic design you may have Digital circuits also called Logic Circuits and Analog circuits. Each circuit may have separate power and ground lines. So you may see the notation on a schematic for Logic Ground or Analog ground.
What is the difference between parallel and series?
If you are referring to an electrical circuit, a series circuit is wired in such a way that if one object is removed from the circuit, the circuit is broken and everything within the circuit loses power. In a parallel circuit different components of the circuit can be removed without disabling power to the rest of the devices within the circuit.
Why do electric circuits have to be complete?
if they're not then the circuit will not work and it won't be able to power wat u want it to power for example a lightbulb.it will be an open circuit
