Electricians install, test, and maintain electrical systems.

Electricians work with electrical power, lighting, and control systems in homes, businesses, and factories.

All electricians use tools such as:

• Screwdrivers
• Pliers
• Knives
• Hacksaws
• Power tools
• Voltmeters

Electricians read blueprints and install new electrical systems. They also perform maintenance on existing systems when something isn't working or needs to be moved.

When working on complex electronic devices, they may consult engineers or industrial machinery repairers. Electricians may also consult with other specialists such as elevator installers or heating and air conditioning workers. Some electricians have helpers that they supervise and train.
