Hello!

I’m looking at doing a panel swap for remodel where I’ll have to move the panel a small amount my concern is if I need to extend the wires no more that 2 feet will i need to arc fault / GFCI protect the circuits I had to splice to get into new panel because the nm jacket will not reach. Also I’m looking for a super clean j box designed for just this thing were it sits on top the panels in she stud bay any links to the right box !? Thank you very much for your advice ! Pictures attached a 2x4 wall will be build for panel to sit in
 
I would just add a screw cover box and a few nipples. If they're 24" or less you won't need to worry about derating.

The exception to 210.12(D) was clarified in the 2020 code to say that only the length of wire outside of the two enclosures is included in the six foot maximum extension. The wire inside of the enclosures is not counted.

Which if I remember correctly was not the original intent of adding the 6' rule to the AFCI requirement. Maybe Dennis will chime in.

Only the wire outside of the enclosures is a hazard. Dennis submitted the PI that changed the exception with the following substantiation.
I wrote this section but the code panel members added the 6' limitation. IMO, this is not long enough. I wrote the section to cover panel change outs where wires would not reach and had to be extended. If the wire has to be spliced in an attic or a crawl space and we add the amount of wire inside the panel and splice box then it defeats the purpose of this section. I don't believe the wiring inside the panel or a junction box should count in the measurement and from experience a few extra feet is very helpful when high ceilings are encountered.

His original proposal for the 2104 code is below:
2-115 Log #536 NEC-P02 Final Action: Accept in Principle
(210.12(B))
________________________________________________________________
Submitter: Dennis Alwon, Alwon Electric Inc.
Recommendation: Add new text to read as follows:
Exception: Where extension of the branch circuit does not include any added outlets or devices.
Substantiation: Often times when changing a service in an older home the branch circuit conductors do not reach the new location of the panel. The wire is sometimes just spliced inside the panel to reach the termination points while other times the circuit may need to be extended a short distance to reach the new location. Since many areas are inspecting this differently throughout the country this exception would clarify this section and bring uniformity throughout.
Panel Meeting Action: Accept in Principle
Revise the proposed wording to read as follows:
“Exception: AFCI protection shall not be required where the extension of the existing conductors is not more than 1.8 m (6 ft.) and does not include any additional outlets or devices.”
Panel Statement: The revised wording provides clarity and satisfies the intent
Number Eligible to Vote: 11
Ballot Results: Affirmative: 9 Negative: 1 Abstain: 1
