Electrical services in England - by Wikipedia

Competency standards in the UK are defined by the Sector Skills council Summit Skills. Qualifications certificated by awarding organisations such as City and Guilds and EAL are based on these National Occupational Standards. Once qualified and demonstrating the required level of competence an Electrician can register with the JIB (Joint industry Board) for an Electrotechnical Certification Scheme (ECS) card. Electrical competence is required at Level 3 to practice as an electrician in the UK. The electrical industry is one of the few that require a trade test to be achieved prior to being fully qualified. This is known as the AM2.

Wikipedia about the job of linesman

A lineman (American English) or linesman (British English), also occasionally called a lineworker, powerline technician (PLT), or a powerline worker, is a tradesman who constructs and maintains electric power transmission and distribution facilities. The term is also used for those who install and maintain telephone, telegraph, cable TV and more recent fiber optic lines.

The term refers to those who work in generally outdoor installation and maintenance jobs. Those who install and maintain electrical wiring inside buildings are electricians.

Electric charge

Electric charge is the physical property of matter that causes it to experience a force when placed in an electromagnetic field. There are two types of electric charges: positive and negative. Like charges repel and unlike attract. An object (one not made of antimatter) is negatively charged if it has an excess of electrons, and is otherwise positively charged or uncharged. The SI derived unit of electric charge is the coulomb (C). In electrical engineering, it is also common to use the ampere-hour (Ah), and, in chemistry, it is common to use the elementary charge (e) as a unit. The symbol Q often denotes charge. Early knowledge of how charged substances interact is now called classical electrodynamics, and is still accurate for problems that don't require consideration of quantum effects.

The electric charge is a fundamental conserved property of some subatomic particles, which determines their electromagnetic interaction. Electrically charged matter is influenced by, and produces, electromagnetic fields. The interaction between a moving charge and an electromagnetic field is the source of the electromagnetic force, which is one of the four fundamental forces (See also: magnetic field).
