help I don't understand 406.4.d GFCI. CAN I FEED OFF A GFCI BREAKER TO OTHER OUTLETS. OR MUST I USE A GFCI OUTLET.
 
2017 NEC 406.4(D) is about replacing existing receptacle outlet devices. The replacement receptacle outlet device must be installed in a manner that results in GFCI protection on that which is plugged into the receptacle. Whether, or not, the replacement receptacle outlet device is a GFCI is a design choice based upon the wiring method conditions. You have to result, when you are finished, in being able to do a 5.0 milliamp ground fault test with something plugged into the replacement receptacle and get a trip in the GFCI, where ever it is (right there, upstream in another device or at the circuit breaker.)

Yes, a single GFCI receptacle may be used to protect down-stream receptacles.

Each receptacle must be GFCI protected, but does not have to be a GFCI device.
 
You are replacing old two wire receptacles with grounding receptacles and there is no EGC right?

  • You can replace every receptacle with a GFCI receptacle.
  • You can replace one receptacle in the circuit with a GFCI receptacle and use the feed through to supply the rest of the receptacles after it. You can either leave the old two wire receptacles or replace any or all with grounding receptacles.
  • You can install a GFCI breaker to supply that circuit. Again you can either leave the old two wire receptacles or replace any or all with grounding receptacles.

In all cases you have to put labels on all grounding receptacles that says "no equipment ground". They will come with the GFCI receptacles or you have to make them up.

To add to Hal's post, any EGCs in such a circuit (typically extensions made with new cable) should not be connected to each other or to grounding receptacles. You wouldn't want a hot-to-case fault in one load to energize the case of another.

Instead of my imagining a whole lot of imaginary things, why don't you share what you are working on. Let us offer some ideas, and examples, about the wiring you are asking about. You've seen the job, yes?
