Always err on the side of caution and seek the help of a licensed electrician.
“Hiring a licensed electrical contractor to complete any new builds or additions in your home or business is an absolutely necessary expense. Even if your project may appear to be less complicated, like modifying an existing building or adding a second room, the skills of a professional electrician will go a long way towards both the safety and the integrity of your final product. Many of our customer have some experience with electrical work, but when it comes to something as potentially dangerous as wiring and electricity, we always recommend erring on the side of caution by hiring a professional.”
