Electrical Wiring

Charging is due to transfer of electrons from one body to another body. Electrons have mass, therefore, mass increases in the case of negatively charged body and decreases in the case of positively charged body.

The red wire typically goes to L2, while the black wire goes to L1. The earth wire should be connected to the earth terminal or grounding screw. Make sure to consult the wiring diagram or a professional electrician to ensure the correct and safe connection.

Electrical symbols are used on electrical prints to show the location of devices that the architect would like located at specific spots. Two simple circuits in house wiring would be a receptacle circuit and a lighting circuit.

The movement of charges in response to a potential difference is called an electric current. This flow of charged particles creates an electric field and is the basis for the operation of electrical circuits.

The neutral provides a path back to the source for the electricity. In a three-phase circuit, it is mainly used to carry the unbalanced load back to the source. In theory, a perfectly-balanced three-phase circuit would not need a neutral, but this is almost impossible to achieve in actual practice.

Simply put, it is any electrical outlet the has three holes that the female end plugs into. What this is referred to most of the time (but not always) is a regular 110V outlet. Older outlets had only two holes, one for the hot, one for the neutral. All newer installations have the third hole for the ground wire.

No, it is not recommended to run a 570 volt motor on a 480 volt power supply. The motor is rated for a specific voltage to ensure optimal performance and prevent damage. Running the motor at a lower voltage could result in overheating and premature failure.

For a 1500 watt 120 volt heater located 400 feet away, you would need to use at least 10-gauge wire to minimize voltage drop and ensure efficient power transmission. It is recommended to install a 240 volt sub panel near the heater location to account for the distance and potential power requirements for additional lights or equipment.

The neutral grounding resistor fail-safe relay is designed to monitor the continuity of the neutral grounding resistor. If the resistor fails or becomes disconnected, the relay will detect the fault and trip the system to prevent overvoltages that could damage equipment or injure personnel. This helps maintain a safe and reliable electrical system by ensuring proper grounding.

The electrical code states that motor feeders have to be rated at 125% of the FLA of the motor. When wiring motor circuits always consider the ambient temperature (for wire de-rate purposes) where the motor is located and the 125% rule before selecting the correct wire size.

Extra care must be taken when calculating power requirements for circuits that will carry electric motors because the current need of an electric motor is larger than calculated from its horsepower rating alone. Electric motors are highly inductive and also have an in-rush current requirement to get started. The circuit used to power an electric motor has to be capable of supplying the in-rush and steady state currents to the motor -- with an acceptable I^2-R loss on the wires.

The green wire is the ground wire, which is used for safety to prevent electric shock. The white wire is the neutral wire, which completes the circuit and carries the return current back to the electrical panel.

To wire a 240-volt light fixture, you'll need to ensure you have a dedicated circuit with a 240-volt power supply. You will connect the fixture's hot wire to one of the hot wires from the circuit, the neutral wire to the neutral wire, and the ground wire to the ground wire. It's crucial to follow the manufacturer's instructions and consult a licensed electrician if you're unsure.

Not typically. Domestic service in many areas of Japan is similar to US Network services in that it provides two phases, like ABN to a service, then BCN to the next, etcetera. There are appliances in the US designed for Network services; but then there is the question of the plug at the end of the cord -- will it match both physically and electrically. It is best to first identify where in Japan you want plug the appliance and second find out available electric service parameters -- they still have some DC over there...

No, a dynamometer is not used to test electrical safety. A dynamometer is a device used to measure mechanical force, torque or power. Electrical safety testing is typically done using instruments such as multimeters, insulation testers, and ground resistance testers.

In a three phase that means there are three lines live. Lets name the first line L1, second one L2 and the last L3. If you would connet it to a three phase motor then you require L1, L2 and L3 to be connected either in star or delta connection. Rating of your motor should be 200V, 3 phase , x HP ( star or delta connected). If you have a single motor of 200V then you only need to connect two lines of the three., namely either L1 to L2 , L1 to L3 or L2 to L3.

the green wire its ground so you have black withe an ground

For a 220 volt dryer, a 10-gauge wire is typically used for the connection from the breaker to the outlet. It is important to ensure that the wire matches the amperage rating of your breaker to maintain safety and efficiency in the circuit. Consulting local electrical codes and a professional electrician is recommended for accurate specifications.

The formula you are looking for is I = HP x 746/1.73 x E x %eff x pf.

I = 700 x 746 = 522200/1.73 x 4160 x .91 x .92 = 522200/6025 = 87 amps.

A standard motor's efficiency between 5 to 100 HP is .84 to .91.

A standard motor's power factor between 10 to 100 HP is .86 to .92.

Motor feeders have to be rated at 125% of the motors full load amps. 87 x 125% = 109 amps.

A #2 copper conductor with an insulation factor of 75 or 90 degrees C is rated at 115 and 130 amps respectively.

This wire has to have an insulation voltage rating of 5000 volts.

Yes, an electrical switch can be installed before a GFCI outlet in a circuit. Just ensure that the wiring is done correctly, following all safety guidelines and local electrical codes. The GFCI outlet should be properly connected to the power source and the switch should be wired to control the flow of electricity to the outlet.

The insulator between the contacts of a bell push when it is off is typically made of a non-conductive material such as rubber or plastic. This insulator prevents electrical current from flowing between the contacts when the bell push is not being pressed, thus keeping the circuit open.

A group of ten (10) batteries composed of 6 Volt and 12 Volt types will have six (6) each, 6 Volt and four (4) each 12 Volt batteries. The contributing voltages will be 6x6 and 12x4 for a total of 84 Volts.
