I want to work as an electrician but I’m not qualified… what licenses do I need? Are they very expensive?

Hello, this week I’ve to do some stuff in an electric workshop and I’d like to know how I could reduce the risk of fire or electric shock.

Electricians are required to install and maintain electronic and electrical systems. They can work for a local authority providing services for housing and property services departments. These professionals also work on public highways repairing street lights. They follow architect’s drawings in order to install wiring systems in a building and then they connect switches, light fittings and sockets to this system.

Electricians usually perform many of the following tasks:
• Maintaining equipment.
• Installing wiring systems.
• Repairing street lighting.
• Fitting circuit breakers.
• Connecting wiring to appliances.
