Hookup wire vs NM-B behind walls

I ran four separate 10 gauge 600 volt PVC insulated wires through conduit from one side of my garage to a junction box near my panel for a 220 VAC power source I need. I need to go from the junction box into the panel itself to connect to a 30 amp GFCI breaker I've installed. My question is this: Do I need to run NM-B wire from the junction box into the panel (behind the wallboard) or can I run the individual 10 gauge wires? The run length from junction box to breaker is about three feet.

Thanks ahead!

You can rule a cable or individual conductors in a conduit. Individual conductors cannot be used loose in the wall.

You only need 2 wires plus ground for 240 (you don't have 220). You only need 4 wires if it is 120/240. What are you hooking up?

Why not use some more PVC conduit into the service panel?

Ray2047, I'm running a neutral as there's a control panel that manages the 240 load that runs on 120.

Furd, it might be easier to run cable instead of conduit behind the wallboard. It's tight back there.

Several kinds of cable you could run ( inside the wall ? ) . Or flexible conduit with individual conductors .

God bless
