Yes, you can use 110V from two phases instead of 220V, but it depends on the specific application and equipment requirements. If your device is designed to operate on 220V, using 110V may not provide sufficient power, potentially leading to inadequate performance or damage. Additionally, ensure that the two 110V phases are correctly configured to avoid any electrical issues. Always consult an electrician or refer to the device's specifications before making changes.
The fact that it's supposed to. Voltage is stated as the difference between the two wires carrying electricity to the load. When they bring power to the house from the utility, you get two wires carrying 110v but they're 180 degrees out of phase. Imagine one carries positive 110v and the other carries negative 110v. If you hook one of these wires plus a neutral (zero volts) to the load, you get 110v--110v over 0v. If you hook both of them to the load, you get positive 110v over negative 110v, or 220v. So...red to white is 110v, black to white is 110v, red to black is 220v.
No, you cannot run a 110V 20A circuit off one leg of a GE THQP 220V 20A breaker. A 220V breaker is designed to provide two hot legs, each supplying 110V, but when using only one leg, it does not provide the proper grounding or neutral configuration needed for a standard 110V circuit. Additionally, this could lead to potential safety hazards and code violations. Always consult a qualified electrician for proper circuit configurations.
Yes and no. For any given power usage, the current in a 220V system is half that of a 110V system. Therefore, cables in a 220V system can be thinner than 110V. Furthermore, a voltage drop of, say, 5V due to the resistance of wires is less significant in a 220V system than 110V. So, there is an economy with wiring. However, touch 220V and there is a good likelyhood that it can prove fatal. Do the same with 110V and it will hurt, but it is less likely to prove fatal. Therefore, 220V systems will generally be of a higher safety standard (read more expensive). For example, US lighting is often wired with single insulated cable. European regulations demand that an additional insulating cover is used on all cables. Other regulations in Europe make more demands on installation methods, all of which push up costs. It is unlikely that a full comparison will show a lot of difference between the two.
This is only valid in parts of the work using 110/220 Volt split phase power system. There will be 110V from each of the hot leads to ground/neutral, so connect your outlet to only one of the hot leads, the neutral lead and the earth ground lead. This may be a problem with a dedicated 220V circuit as there will likely be no neutral line. Another note - this could well cause an unbalanced electrical load across the two pole breaker. If the breaker has a rating of 20A and the 110V circuit draws much of that current, the heater will likely trip the breaker.
No. The black is 220, the red is 220, and the ground serves as the neutral. the last answer "no" is correct but the reason is not. the ground is still a ground. the red is 110v and the black is 110v. together they are 220v. the neutral or (common) is for a 110v return. for example a stove or a dryer will have 2 hots a common and a ground because they use 220v and 110v. 220v to power the heating elements and 110 for the controls, light bulbs or the outlet on a stove. A construction heater only uses 220v and only requires the two hots and the ground for safety.

A 220v heater has two 110v lines coming into it--either two 110v lines with a neutral, like a range, or two 110v lines with no neutral, like a water heater. Unless there's a fan in the system, they only use two wires. It's cheaper that way. If you have a DEDICATED circuit for each 220v heater--one where there's only one thing on the breaker--and you have at least 10/2 wire (unless the amps call for 8/2 or 6/2 wiring, which happens), you can install a two-pole breaker to feed 220v to the heater. If you're just trying to plug the heater into an outlet and get it to work, you've got a problem in that you can't pull 220v out of a 110v outlet no matter how hard you try. Sorry.
This is a two part question. Can a 110v outlet be converted into a 220v outlet, yes it can. The other part of the question needs to be discussed.
The main difference between a 220v and 240v electrical system is the voltage level. A 220v system typically refers to a split-phase system where the voltage is divided into two 110v legs, while a 240v system usually refers to a single-phase system with a higher voltage level. In practical terms, the difference is minimal and most appliances and devices can work interchangeably on both systems.
No. Freinds don't let freinds do shabby electric work. Do it right.
Both screws are brass because in the US you need two hots to get 220V. In a 220V only circuit you do not connect the neutral, only two hots and a ground. This is why 220V breakers are twice as wide as 110V and have two terminals instead of one.
Three phase or two phase? Three phase requires three large wires for the current needed

On a three wire supply system if you connect the two 110V wires together and they are across the phase they will short out and trip the breaker. If the two 110V wires are supplied from across the phase and connected to a motor then the motor will run. If the 110V wires are on the same phase nothing will happen.
The two 110V buses are 180 degrees out of phase. This is known as 120/240 split phase power, with the center point called neutral and connected to (protective earth) ground back at the distribution panel.
In a three phase panel a double pole single throw breaker is definatly putting out 220v as two separate 110v circuits that are out of phase with each other. So from one leg to the other its 220v and from either leg to ground its 110v. By definition it is 220v but it could be used as separate 110v circuits as well. The only way to know how its actually being used would be to open up the sign and see if both circuits are tied into one ballast as 220v or if they split and go to differant ballasts then they are 110v circuits using a common disconnect means. Being that either way both circuits terminate in the same area they technically both require a double pole single throw breaker.
