Generally a prototype is built and extensive tests are conducted on it to make sure that it
works as designed and that all of the components work well together. An electrical
engineer might test existing products that have malfunctioned or broken to determine
what went wrong and whether any design flaws can be corrected
The engineer often is responsible for overseeing the installation of the product to ensure
that it is installed properly and safely. The electrical engineer will often create technical
drawings, instructions, and specifications that can be followed to ensure that the product
will be properly installed and correctly operated.
