multiple GFCI duplex receptacles on one circuit?

[melissas1]

Does the NEC permit multiple GFCI receptacles on the same circuit for residential wiring? Is only one required to protect all outlets above kitchen countertops? Or is each box containing two receptacles above a kitchen countertop required to be GFCI-protected by a GFCI outlet in that box?

Any way you want to do it.

No. You need at least two because two SABCs are required on the c-top.

The GFCI and the protected receptacle(s) need not be in the same box.

Yes of course

Is only one required to protect all outlets above kitchen countertops?

No, you need minimum 2 circuits to supply kitchen countertop receptacles and you need at least one GFCI per circuit

Or is each box containing two receptacles above a kitchen countertop required to be GFCI-protected by a GFCI...

Yes ALL 120v 15a and 20a receptacles above a kitchen counter must be GFCI protected.

... to be GFCI-protected by a GFCI outlet

Doesn't need to be a GFCI outlet that is means of protection. A circuit breaker GFCI would suffice

... by a GFCI outlet in that box?

The device providing the GFCI protection is not required to be located at each and every receptacle location.

The requirement of 210.8(A) is that 120v 15a and 20a receptacles "shall have ground-fault circuit-interrupter protection for personnel". Which really just means that so long as a GFCI device is properly installed upstream then you have met the requirement.

We as a company have adopted the practice of installing all CIRCUIT BREAKER style GFCI and AFCI devices where the protection is required in lieu of outlet style. This saves a small amount of money in locations where both GFCI and AFCI is required (like the kitchen). As an added benefit, if something has tripped, no matter the cause, it's always at the circuit breaker.
