A kitchen might benefit from more storage space and counter space with the addition of an island. According to the National Fire Protection Association, the presence of an electrical receptacle on an island is required by the National Electrical Code if the island has a countertop area that is bigger than 12 by 24 inches. This is the case for the usual island. Running the wire under the floor is the simplest way to get it to the outlet; however, this may not be an option if the floor is made of concrete or if you are unable to access the space below it. If this is the case, you may route it down a decorative pillar after passing it through the attic.
