Electricity Rules For Electrical Outlet / Countertops
The National Electrical Code (NEC) has a number of rules regarding the correct placement of an electrical outlet above countertops.
The primary rule is called the 12 / 24 rule as it stipulates that countertops that have free area where the dimensions are greater than 12 inches x 24 inches must have an electrical outlet above the counter tops.
This rule applies to all countertops with the exception of bathrooms (where separate rules apply) including bars, islands (which have some exceptions), and peninsulas.

If you are remodeling a kitchen or doing a major diy kitchen home improvement, it is important to keep the 12 / 24 rule in mind as a change in the dimension of countertops by as little as one inch can change your electrical outlet requirements.
Following is a pictorial description of the electrical outlet requirements for kitchen countertops:
Figure 1 - Placement of electrical outlets on countertops with sink or cooktop
As shown in Figure 1 above, the break in the countertop does not have to be complete. In this case the insertion of a sink or cooktop in the countertop creates, as to the rules in the National Electrical Code, two separate countertops, one that would require an electrical outlet and one that would not.
Countertops require an electrical outlet to be placed a minimum of 2 feet from a wall or end of the countertop and another no more than 4 feet from it, if the countertop is greater than 4 feet in length but less than 6 feet in length there must be 2 electrical outlets. A countertop that is greater than 6 feet but less than 8 feet would require 3 electrical outlets.
A homeowner should remember that this is a minimum requirement and if, because of the number of appliances or devices that you may wish to have on a countertop exceeds the electrical outlet minimum there is nothing within the code that prevents you from adding electrical outlets.
Remember that all kitchen electrical outlets must be GFCI protected, either with a special GFCI electrical outlet or a GFCI circuit breaker.
The electrical outlets must be no more than 18 inches above the countertop and may be mounted in a vertical or horizontal direction, see Figures 2a and 2b.
