Well, I don't think there is a checklist of attributes you need to meet. Just like any career, electrician work attracts all sorts of people. That said, some traits are likely to make your life in this career easier.
Having a curious nature is a useful thing for an electrician, for example. You'll often find yourself tinkering with different systems and learning about new technologies. This profession constantly evolves, so being eager to learn and adapt is a big plus.
It also makes the process of taking classes and studying for different certifications more enjoyable. As the All Electrical Training website shows, there is a lot that an electrician has to study for, even years into the profession.
Attention to detail is another important attribute. Working with electrical systems requires precision and care to ensure safety and functionality. You will need to be thorough and meticulous in your work.
Lastly, being a good communicator helps a lot. You'll often work with clients, other electricians, and different tradespeople. Explaining issues and solutions clearly is important. But then again, it's hard to find a profession where communication skills aren't useful.
