Neutral wires are not as neutral as they sound, often carrying the same amount of electricity as any other wire in the power system. In a confusing tangle of cables and wires, industry standard wire color codes are used to communicate to electricians, maintenance workers, and employees the fun...
The purpose of the neutral wire is to carry back the unbalance of the load. So in a normal (US) house of120/240 voltssingle phase, if one of your hot wires is carrying 30 amps and the other is carrying 23 amps, then the neutral will have to be able to carry 7 amps to keep the...

AC power comes in a variety types based upon the number of volts the wires will be carrying. This voltage is often found in homes and businesses that don't require a lot of energy. For AC Power using these amounts of voltage, the neutral wire color will be white. AC Power (277/480...
I don't really understand how negative voltage works. I will have to do some more research on this.When the Live wire is in it's negative state, doesn't that mean that Neutral is +240v relative to the Live wire? Sorry if these are stupid questions. I'm having some trouble wrapping ...
Shielding wires are located over the load-carrying conductors on transmission lines to prevent a direct lightning strike. Almost all lines above 34.5 kV employ shielding wires. The shield wire provides a 30° protection on either side of the wires. The number and location of the shielding wires...
The star connection of the three phases of a supply, together with a neutral conductor, allows the use of two voltages — the phase voltage and the line voltage. A 4-wire system is also used when the load is not balanced. The standard electricity supply to consumers in Great Britain is ...
Figure 1. The 3-wire system. Click to Enlarge The hot and neutral wires are interchangeable as far as the equipment is concerned. Both are power carrying wires. One of the power carrying wires is grounded at the source for reasons of safety (see the appendix: “the origin of the 3-wire...
Because the garage electrical system was carrying current that should have been flowing only on the insulated neutral wires in the building, when the owner touched his grounded metal work bench and was also touching a damp floor, current flowed through the ground wire, through the metal work ben...
Hello, I am having trouble understanding the neutral wire in a split-phase system. In the All About Circuits E-book chapter about single-phase power systems...
