For many reasons, you should never attempt to do electrical work on your own.
No matter how simple the task might be, fires, electrical shock and serious injury can occur if the work is not done correctly.
Some states will not pay for any damages if electrical work is not done by a professional, licensed and insured electrician.
If the work is more involved, there are building codes to be followed and inspections that must take place.
Everyone wants to save money, but doing electrical work yourself can cost you more in the long run if you attempt to take things into your own hands. Even installing a simple light switch can be done incorrectly if you don’t know exactly what you are doing.
