Electricians won’t get any bonus points for organization. Technically, the ability for the wiring to conduct electricity has nothing to do with how organized the cables are. Still, if you look at your wiring and see a haphazard mess, take caution. There could be a larger problem at play.
Signs of disorganization indicate that an electrician was in a rush or that he or she didn’t care about the work. Don’t settle for a wiring rat’s nest. If you see tangled wires, have your electrical wiring inspected as soon as possible. It’s better to be safe when regarding the integrity of your home.
