Working with electricity has its risks and includes a high level of difficulty. That is why most localities insist professionals perform electrical services and require inspections to make sure the work is done correctly. Electrical work that is not done correctly can result in electrical fires and shocks to people using the space. Electrical companies must be licensed, bonded, and insured for commercial, industrial, and residential electrical services. This is one aspect of home improvement that does not lend itself well to DIY projects.
