Most TVs require a standard outlet, which costs between $130 and $290 for materials and installation. Installing an outlet for your TV or entertainment unit offers enhanced convenience and safety compared to using multiple extension cords.
Most countertop and over-the-range microwaves require a 120V, three-prong outlet on a dedicated circuit. The cost of these outlets is on the higher end of the typical 120V cost range.
Replacing a light switch costs approximately $10 to $30 per switch. Material costs depend on the type of switch. Standard switches can cost just $1, while high-end smart switches and other options can cost $500 or more.
