Here's the section from your question:Example:
In a single family dwelling, code states that a minimum of (2) two 20 amp GFCI protected circuits are required for the kitchen countertop receptacles.
If both (two) of the 20 amp kitchen countertop circuits have a quantity of (4) four 20 amp duplexes each and each OCDP is 20 amp GFCI, does Table 210.21(B)(2) apply since all (4) four of the duplexes on each branch circuit will be cord & plug connected to accomodate small plugged-in kitchen appliances? If Table 210.21(B)(2) is applicable in this example, what is the maximum OCPD load for the circuit on this example 16 or 20 amps?
In your example you have 8 receptacles (4 duplex) on a 20 amp circuit. The load on any one of those 8 receptacles cannot exceed the ampacity from the table which would be 16 amps for a 20 amp device or 12 amps for a 15 amp device.210.21(B)(2) Total Cord-and-Plug-Connected Load. Where con-
nected to a branch circuit supplying two or more receptacles
or outlets, a receptacle shall not supply a total cord-and-plug-
connected load in excess of the maximum specified in Table
