Linemen work on live wires by using proper insulation gear, and by making sure that there is never any path for current to flow in case the insulation does fail. In some cases, the lineman can be raised to the potential of the line, but you still need the insulation, and you still need the technique of ensuring that no circuit can be accidentally created.

If you have an air solenoid valve DC and the wires are Green Black and White. Which one is positive and negative?
Green= Ground Black = live White = Neutral
Did in philippines have a 2 phase electricity line supply as of now specially in residential houses...?
Two-phase systems have not been in general use for about 100 years because they were replaced by three-phase systems worldwide. Another type of power that is still used is 'split-phase' which is a single-phase supply using a centre-tapped transformer. For example a supply transformer has a 240 v secondary with a grounded centre-tap, so that two separate 120 v live wires are connected to the property, along with the neutral. High-power appliances like cookers or aircon can be connected across the two live wires to work at 240 v. Split-phase is also used in Europe with a 460 v centre tapped transformer used to supply a relatively small remote community, with individual properties fed a 230 v supply from one or other of the two live wires plus the neutral. The advantage is that it reduces the current in the neutral wire, and if both live wires happen to supply equal currents the neutral current going back to the transformer is zero, thus reducing power lost in the wire.

List three examples of how insulators are used?
rubber or plasic is used as an electical insulator to cover wires to prevent against elecric shock. Gloves are used over hands as a thermal insulator to prevent burns while holding hot objects. insulated footwear are used when working in an enviorment dealing with many exposed live wires.
If a light bulb is connected between 2 wires and both wires have 300 volts of electrical energy is the light bulb lit?
A light bulb connected between to wires, each having 300 volts to ground that are in phase, will not light, because there is no differential voltage available to do any work. If each wire has 300 volts to ground and are out of phase (600 volts between them) the light bulb will be lit, if it is rated at least for 600 volts, otherwise it will burn out.
Who does electrical work?
Electricians are trained to work in the electrical trade. Linemen are trained to work on the primary high voltage side of the electrical trade.

What are the dangers present when doing electrical work?
There are many dangers present when doing electrical work including overhead power cables and electrical wires which are obvious and then there are the less obvious ones like cables underground and loose live wires. It is advisable not to do electrical work if you are not a trained professional.
If you had to choose two positions and you want to tryout for a linebacker on defense more than a running back on offense should you workout withe linemen or with the Receivers back?
During practice go with the linemen, but at home work on your speed and endurance by yourself. (including agility)

How to become an Electrical Lineman?
Linemen (this is the term used even for women working in the field) are sometimes called lineworkers, power line technicians (PLTs), or a power line workers. They are the professionals to construct, rig, and maintain electrical power lines, distribution centers, fiber optic lines, and lines or cables for telegraph and television transmissions.Linemen work outside almost exclusively, in all sorts of weather and conditions, including high level wire work on telephone poles and electrical towers. They are often working with “live” wires, running current. Their duties require acute observational skills, attention to detail, and extreme manual dexterity and physical strength for climbing and using special equipment. Linemen often work as part of a team, so communication skills are important.In terms of education, linemen need a high school diploma or GED that includes at least a year of algebra, plus specific training and qualifications gained through certifications or professional official apprenticeships served under experienced senior linemen. Many linemen finish high school then get a two-year Associates technical degree while they work as an apprentice. Many trade schools and community colleges offer specific training and certificates for linemen, though it is important to make sure that the program offers training regarding electrical distribution theory as well as hands-on practical labs. Many people finish high school and get a jump-start on lineman training by working for a local contractor in hopes of being apprenticed.Apprenticeship qualifications (http://www.electricaltrainingalliance.org/training/apprenticeshipTraining) include a year of high school algebra, successfully passing a drug test, and qualifying score on an aptitude test. The IBEW, the official trade organization for linemen, offers information about training including locations with approved training and information about colleges offering approved two year associates degrees and four year bachelors degrees designed to prepare students for future jobs as linemen.
