120 volts 1 phase 30 amps load what wire size?
For a 30 amp load on a 120 volt 1-phase system, you should use at least a 10-gauge copper wire to ensure safety and efficiency. Additionally, it is always recommended to consult with a licensed electrician to determine the exact wire size needed for your specific application.
Is a Line voltage understood to be any voltage?
The Line normally refers to the live wire in a single-phase system and the three live wire of a 3-phase system. In a 3-phase system the line voltage is usually quoted as the nominal voltage, and that is the voltage between any two of the live wires. The voltage between one of the lines and neutral is 1/sqrt(3) times less.
How do you calculate phase voltage of a three phase four wire system?
Phase voltage is determined by the wiring of transformer that serves the building. To test phase voltage use a volt meter and put one probe to ground and the other to each phase and observe the reading, this will give you a phase to ground voltage reading. Next test phase to phase (1 to 2, 1 to 3, and 2 to 3) to see if it's 208, 240, 277, or 480. Only licensed electricians should perform these tests. DAW
How do you obtain a 230 volts single phase supply from a 400 volts three phase four wire supply?
400 volt three phase on a grounded system is 230 volt single phase, with each phase 120 degrees apart. So, if you have a 400 volt, three phase four wire service (grounded service), you can pull one phase off and reference to the neutral for 230 volt service. Note this may not allow 115 volt service, unless there is also a center tap for each phase.
How can I change 2 wire 220 1 phase to 4 wire 220 single phase to run an electric range?
To change from a 2-wire 220V connection to a 4-wire 220V connection for an electric range, you will need to install a separate ground wire. This typically involves running a new wire to the grounding terminal in the electrical panel and connecting it to the range outlet. It's important to ensure that the wiring is done properly and meets local electrical codes for safety. If you are unsure, it's best to consult a qualified electrician for assistance.
What are the procedures for the connection of single and 3 phase circuits?
Single phase connection has 1 phase wire and a neutral wire. Another wire for protective earth. In three phase system, motor can be connected in star or delta. Most AC induction motors are in Delta. Power distribution system is generally 3 phase 4 wire. Transmission system is 3 phase high voltage. Industry uses 3 phase system, where as 1 phase is for domestic, commercial applications. Both 1 and 3 phase system has a frequency. It is either 50 Hz or 60 Hz, depending upon the country or region.
How do you hook up a 3 phase water heater to a 3 wires 1 white 1 black 1 bare copper ground?
In order to answer your question, firstly, we have to accurately establish your supply.Is it 2 phase or 2 wire?2 phase is two active conductors, i.e. 2 live wires with reference to neutral or ground2 wire is single phase, an active and a neutral conductor.2 phase supply is uncommon.Single phase (2 wire) is the more common supply and for installations with large loads three phase, or, more appropriately 3 phase and neutral (4 wire) is used.Please confirm your supply so that a detailed answer can be provided.
Why neutral wire current is more in 1-phase than the 3-phase?
On a typical house plug, there are three wires - the positive, neutral, and ground. Ideally, the positive and neutral wires carry the current (the neutral wire provides the return path for the current from the positive wire), and the ground wire carries no current. In a three phase system, you have three phase voltages of the same magnitude (ideally), but the three phase voltages are out of phase with each other by 120 degrees - meaning one is at 0 degrees, one is at 120 degrees, and one is at -120 degrees if you looked at them on an oscilloscope, and referenced to one phase. If you take (1 at an angle of 0 degrees) + (1 at an angle of 120 degrees) + (1 at an angle of -120 degrees), you will get zero. Thus the return path in three phase power is shared between the three phases, and the neutral wire in a 4 wire, three phase system is equivalent to the ground wire connected to your wall plug. The ground wire will only carry current when the "vector sum of the phase voltages does not equal zero" (meaning the simple equation at the beginning of this paragraph does not sum to zero - whatever it sums to is what is flowing in the neutral).
How can you determine if a electric motor is 1 phase or 3 phase if there is no name plate?
Check the motor's terminal box. If there are three service input cables - such as red, yellow and blue - plus an earth wire, then it is a three phase motor. If there are only two wires plus an earth wire, then it is single phase.
What is the difference between 1 2 and 3 phase?
The main difference between single-phase and three-phase power systems is the number of conductors or wires used to distribute electrical power. Single-phase systems have one live wire and one neutral wire, while three-phase systems have three live wires and one neutral wire. Three-phase power is often used in industrial settings for its ability to provide a more stable power supply and handle higher loads more efficiently compared to single-phase power.
Where can one purchase a Roto router?

What's the smallest roto tiller I can buy that will till a small garden effectively?
There is a 1/2 bit troybilt roto tiller that is considered the smallest and based on the reviews can do a small garden prefectly.
What is Electricity use difference between 3 phase and 1 phase?
A two-phase a.c. system is an archaic system, in which two phase voltages are generated 90 electrical degrees apart. It has nothing whatsoever to do with the US 'split phase' system that supplies North American homes. A two-phase system can be a four-wire system, or a three-wire system, and was useful because, unlike a single-phase system, it could create naturally rotating magnetic fields in induction motors. It has long been superseded by the three-phase system.
Where can you find a roto rooter nearest to you and can you get a good estimate?
The best way to find a Roto-Rooter near you is to call their customer service at 1-800-768-6911. They can put you in touch with your local service men who will give you an estimate.
Line voltage is understood to be any voltage?
The Line normally refers to the live wire in a single-phase system and the three live wire of a 3-phase system. In a 3-phase system the line voltage is usually quoted as the nominal voltage, and that is the voltage between any two of the live wires. The voltage between one of the lines and neutral is 1/sqrt(3) times less.
