Just like with a light switch, changing out an electrical outlet is something a novice DIY enthusiast can likely tackle. There's really not much involved beyond cutting the power at the fuse box, removing the outlet from its existing wiring and attaching a new one before popping it back into the wall. Where you get into trouble is when you have an old home with outdated wiring. Home electrical systems are clearer cut these days, but if you have an old house, then that black and white striped wire in the installation diagram may be yellow or brown. This is when a power meter comes in handy. Or maybe your cell phone to call in a professional.
