What is the correct size of main bonding for a TN-S system having 25mm2 phase and neutral conductor is?
The correct size of main bonding for a TN-S system with a 25mm2 phase and neutral conductor would typically be based on the size of the earthing conductors specified by regulations and standards in your region. It is important to consult local electrical codes or a licensed electrician to ensure compliance with safety requirements.

What is the correct size for main bonding conductor for TN-S system having 25mm phase and neutral supply conductors?
In a TN-S system, the size of the main bonding conductor is typically determined based on the size of the largest phase or neutral conductor. For a supply with 25 mm² phase and neutral conductors, the main bonding conductor should generally be sized according to the relevant standards, often around 10 mm² for copper or 16 mm² for aluminum. However, it's essential to consult the specific electrical regulations or codes applicable in your region, as they may provide precise sizing tables and factors for earthing and bonding conductors.
What is the correct size of a main bonding conductor for a tn-s system having a 25mm phase and neutral supply conductors?
For a TN-S system with 25mm² phase and neutral conductors, the main bonding conductor should typically be sized according to the requirements outlined in the IET Wiring Regulations (BS 7671). Generally, the main bonding conductor should be at least 6mm² for copper or 10mm² for aluminum. However, it is essential to refer to the specific regulations and tables to ensure compliance, as factors such as the size of the supply conductors and the installation conditions may influence the final sizing. Always consult the latest edition of the regulations for precise requirements.
Is the neutral conductor a live wire?
YES. ACTUALLY THE SIZE OF NEUTRAL BUSBAR IS BIGGER THAN THE PHASE CURRENT IF ALL THE LOADS IN A 3 PHASE PANELBOARD ARE ALL SINGLE PHASE. In single-phase, which is found in homes, when an appliance is operating, the amps (current) will be equal in the "hot leg" and the neutral. So current IS passing through the neutral wire. In 3-Phase, which is found in a lot of commersial and industrial buildings (including schools), very little current will exist in the neutral IF the current load is BALANCED EQUALLY between the 3 phases. At any given time, however, it is almost impossible to balance the current exactly. So current, even a small amount, will probably exist in the neutral wire. Most certainly enough to harm or kill you! Be it at home, or at work, when the lamp at your desk or by your bed is on, current is flowing through BOTH of the lamp wires!
What is covalent bonding if it is polar?
These are molecules having a significant difference for the electronegativities of the two atoms involved.
Single phase 4 pole Gen alt w 240V 60hz output no neutral. you check from each lead to ground and get 50-70V How do you get a neutral for connecting Gen to a standard breaker box having 240V and 120V?
Neutral is at the jumper that changes it from 120v to 240v. Two stator windings are used in series to make 240v; at that junction is (when wired in Series)your neutral/common/ground. Ground this terminal and use it for your neutral/common. When wired in parallel you have 110v and the jumper is removed and there is no common/neutral and ground is from the frame of the generator.
What is the correct size of main bonding conductors for a tn-s system having 25mm phase?
By rule of thumb, the neutral conductor is half the size of main conductor.

Is the brown cable live in electrical wiring?
all electrical wire but green and white are hot wires in electrical wiring according to the national electrical code NEC in the USA.Answer for UK / European CablesThe correct term is 'line', rather than 'live', with the line conductor having a nominal potential of 230 V with respect to the neutral. As the original answer points out, both line and neutral conductors are defined as 'live' by both the NEC and the equivalent UK regulations.Throughout Europe, brown insulation is used to identify the line conductor of single-phase system. For a three-phase system, the three line conductors are identified as brown, black, and grey.The neutral conductor is identified by blueinsulation, and the protective (earth/ground) conductor is identified by yellow/green striped insulation.
What if the fourth wire in a three phase is having impedance would the current in the neutral line remain to have a value of zero?
When the system is in balance, with three equal phase currents, there is no current in the neutral 4th wire and it is not needed. However if the load is unbalanced, the neutral is needed to maintain the star point at zero volts.So for example a street of houses fed by a 3-phase supply needs a neutral because the houses draw unequal currents from the different phase lines, although a large enough collection of houses would tend to balance itself out.If a three-pase system has equal currents the current in the neutral is zero. If two phases draw equal current but the third has no load, there is an equal current in the neutral, and if one phase draws current but the other two have no load, there is again an equal current in the neutral.ANOTHER ANSWERA three-phase, four-wire, system comprises three line conductors and a neutral conductor. If the load supplied by this system is balanced (i.e. the loads connected between each line and neutral are identical in all respects), then no current will flow in the neutral conductor regardless of its impedance. If the load is unbalanced, then a neutral current will flow in the neutral conductor. In other words, the impedance of the neutral conductor plays no part in whether or not there is a neutral current.
Is blue wire positive?
If you are talking about the wiring of buildings/houses then blue would be a hot with ac current. If you mean wire in electronics then it would also "usually" be a positive but if there is any danger you should never assume. A tester could save you from having to buy a new component or your life.AnswerThe European convention is that blue insulation indicates a neutral conductor, brown, black, or grey insulation indicates a line conductor, and a yellow/green striped conductor indicates an earth conductor.
How do you adapt a single phase 230V 50 Hz machine having total power 5 KW to a three phase system with no neutral?
The earth can be used as a neutral provided the earth is connected to the supply of the network and any of the 3 phases of the supply as a life. All electric supply networks use only 3 HT transmission lines and derived the neutral at the end from the star connection of the step-down transformers secondary windings that is also connected to earth in most countries. There is no neutral running from the power station to the end users step-down transformer, so the earth is a neutral. For more info look at the following link where one can see on the photos of the transmission line only 3 lines is visible. http://en.wikipedia.org/wiki/Three-phase_power See http://en.wikipedia.org/wiki/Ground_and_neutral: Since the neutral point of an electrical supply system is often connected to earth ground, ground and neutral are closely related. Under certain conditions, a conductor used to connect to a system neutral is also used for grounding (earthing) of equipment and structures. Current carried on a grounding conductor can result in objectionable or dangerous voltages appearing on equipment enclosures, so the installation of grounding conductors and neutral conductors is carefully defined in electrical regulations. Where a neutral conductor is used also to connect equipment enclosures to earth, care must be taken that the neutral conductor never rises to a high voltage with respect to local ground.
