Electricians, at times, are referred to as 'WIRERS' due to their job of installing and repairing electrical wiring systems. Electricians are responsible for a variety of tasks related to the installation and maintenance of electrical systems, such as connecting wires, testing circuits, and troubleshooting problems. They also inspect existing wiring systems to ensure they are up to code and safe for use. Electricians must be knowledgeable in the principles of electricity and safety regulations.
