Question GFCI neutral question

Serving a small shop with one circuit. Have two recptaciles being protected off of one GFCI, that GFCI and two lights in the shop. Does the nuetral wire with the GFCI protected hot have to be a seperate nuetral wire for the regular circuit nuetral. In other words do I have to pull two nuetrals in part of the pipe or will one work throughout? Oh and also same question with the ground wire.
Thanks!!!

You need two seperate neutral wires to make that setup work.

But you cannot have GFCI and non GFCI conductors in the same conduit.

If you want the gfci to function properly then you need to connect either line and load to their perspective places- that includes the neutral. You cannot use the gfci neutral to feed a light that is not part of the gfci load.

Neutral & hot must be on the load side of the gfci or both must be on the line side of the gfci.

The gfci senses the current of the neutral and the hot. If it reads 3-5 ma difference between the two then the gfci will trip.

I'm assuming the GFCI protection here is a receptacle?..and you don't want the lights protected? Pigtail your circuit in the GFCI's box and go to the line side of the GFCI and also to the lights. The load side of the GFCI can protect downstream receptacles.
