Running new circuits in outside conduit

I need some clarify on this,

So if I do run

2 blacks, 2 whites and 2 grounds (or 1 ground since that can be share) I can just have two completely seperate 15amps circuit without the dual poles 15 amp breaker setup ( or handled-tied)? I understand the colors of the wire may be confusing when do the wiring but that can be taken care of using differ color.

Thanks

Yep.

I'm curious about something, though. If I was going to do this much work I'd make the circuits 20A each. Is there a reason you're planning to install the lower-capacity circuits?

Wait. I just scrolled back to the beginning of this thread to look for an answer to that. I didn't find one, but I did find a reference to #12 wire, which is rated for 20A. So now I'm confused.

What size wire and what size breakers are you planning to install?

So let say, I do want two competely separate 20A circuits, it is do able with 2 x hot, 2 x neutrals and 2 (or 1) x ground? Let put aside the materials spec of this setup.

Five wires - you only need one ground.

Let's not. Since you specified 20A circuits, the wire must be 12AWG or larger. Since you're running in an exposed exterior conduit, it must be rated THWN.

The two pole or handle tied breakers would only be needed if you only ran one neutral.

I ran mine separately, and also with GFCI protection since they were outdoors.

But that was not required or probably needed unless they went to a special purpose receptacle such as bath or kitchen and those can usually be more cheaply protected with a GFCI receptacle.

In case you missed it, the answer is Yes.

You are running two separate dedicated neutrals so you should be good to go. Only one ground is necessary.

Around here anything that can be plugged into outdoors is GFCI protected. That is also the code requirement. Circuits that begin and end inside the structure, but travel outside without interruption, do not require GFCI protection. As Ray said,
