An electrical drawing is a type of technical drawing that shows information about power, lighting, and communication for an engineering or architectural project.Any electrical working drawing consists of "lines, symbols, dimensions, and notations to accurately convey an engineering's design to the workers, who install the electrical system on the job".
Electrical system design is the design of electrical systems. This can be as simple as a flashlight cell connected through two wires to a light bulb or as involved as the Space Shuttle. Electrical systems are groups of electrical components connected to carry out some operation. Often the systems are combined with other systems.

Modern exit signs are often combined with other safety devices, such as emergency floodlighting for supplementary area illumination. [13] Modern exit signs are also, to some degree, flame retardant. Exit signs draw a relatively small amount of power, and can generally be added onto any existing electrical circuit without adverse effects.
An exit sign designed in accordance with the Directive. The Directive 92/58/EEC specifies the minimum requirements for safety signs within the European Union. [1] It superseded the Directive 77/576/EEC. [1] While not being replaced by the standard ISO 7010, both signage systems can be used. [2]
