Many homeowners try to save money by performing basic electrical repairs on their own, such as replacing a light switch, outlet, or light fixture. What looks to be a simple project could turn into a nightmare due to not knowing the electrical code and inexperience. You could have faulty wiring, overloads, electrical shock, or even a fire. Doing your own electrical work could cost you more in the long run if not done right. The best thing to do is hire a professional licensed and insured electrician.
