Electrical engineering has many sub-disciplines, the most popular of which are listed below, although there are some electrical engineering jobs that focus exclusively on one of these sub-disciplines, many deal with a mixture of them. The sub-disciplines are: power engineering, control engineering, electronic engineering, microelectronics, signal processing, telecommunications engineering, computer engineering, and instrumentation engineering.

Electrical engineering jobs obviously vary according to the industry and sub-discipline they're part of, but broadly can include such things as: design of electrical systems; preparation of design and installation specifications; testing electrical systems and electronic devices; design calculations; support installation, commissioning and decommissioning, etc.

Experience requirements largely focuses on power distribution and control of power (230v and 440v primarily); with professional qualifications generally deemed to be a minimum of an HND or above, in Electrical Engineering (preferably degree of chartered status). CAD proficiency is often desired, as is knowledge of power management systems, UPS systems, commissioning procedures; and the ability to prepare manuals and procedures, design calculations; and manufacture, testing and commissioning support.

Electrical engineering has many sub-disciplines, the most popular of which are listed below
Power
Power engineering deals with the generation, transmission and distribution of electricity as well as the design of a range of related devices. These include transformers, electric generators, electric motors, high voltage engineering and power electronics.

Control
Control engineering focuses on the modeling of a diverse range of dynamic systems and the design of controllers that will cause these systems to behave in the desired manner. To implement such controllers electrical engineers may use electrical circuits, digital signal processors, microcontrollers and PLCs (Programmable Logic Controllers). Control engineering has a wide range of applications from the flight and propulsion systems of commercial airliners to the cruise control present in many modern automobiles. It also plays an important role in industrial automation.

Electronics
Electronic engineering involves the design and testing of electronic circuits that use the properties of components such as resistors, capacitors, inductors, diodes and transistors to achieve a particular functionality.

Microelectronics
Microelectronics engineering deals with the design of very small electronic circuit components for use in an integrated circuit or sometimes for use on their own as a general electronic component. The most common microelectronic components are semiconductor transistors, although all main electronic components (resistors, capacitors, inductors) can be created at a microscopic level.

Signal processing
Signal processing deals with the analysis and manipulations of signals. Signals can be either analog, in which case the signal varies continuously according to the information, or digital, in which case the signal varies according to a series of discrete values representing the information.

Telecommunications
Telecommunications engineering focuses on the transmission of information across a channel such as a coax cable, optical fiber or free space.

Instrumentation engineering
Instrumentation engineering deals with the design of devices to measure physical quantities such as pressure, flow and temperature. The design of such instrumentation requires a good understanding of physics that often extends beyond electromagnetic theory.

Computers
Computer engineering deals with the design of computers and computer systems. This may involve the design of new hardware, the design of PDAs or the use of computers to control an industrial plant. Computer engineers may also work on a system's software.

For many engineers, technical work accounts for only a fraction of the work they do. A lot of time may also be spent on tasks such as discussing proposals with clients, preparing budgets and determining project schedules.Many senior engineers manage a team of technicians or other engineers and for this reason project management skills are important. Most engineering projects involve some form of documentation
and strong written communication skills are therefore very important.
