Making electrical wire longer

[3Ts]

I need to reroute an electrical conduit and will end up making it 2 or 3 feet longer. I hate to replace 4 wires that are 65' long with ones that are 68' long. Is it legal (as in code compliant) to use a crimper to join 2 wires in a butt splice if they are inside a conduit? Amazon has a 10 ton barrel crimper that I would use and these wires are #2 THHN. The splices would be staggered so they're not all in the same place in the conduit.

Note: To replace the wire is about $1k, the crimper and splice barrels are about $50 which is what prompts this question.

pretty sure it has to be in a box, or an approved in wall splice kit if you care about code

I agree just add a splice ready conduit box or a junction box.

I would not have a splice in the conduit itself.

As far as I know it has to be in a box. Unless this will work?

There has to be some place on that 65 foot run where an outlet box would be useful. Closer to one end or the other would be nice (save on wire). But, Do it right! Use a box and wire nuts if nothing else.

Heck! Put in TWO outlet boxes "somewhere" . A good layout might not waste much wire at all, and provide some convenience.

He's talking about 2 AWG THHN. Gonna be pretty tough getting that wrapped around the terminals on an outlet.

I really should read the o.p. ;-)

NEC requires splices to be in a box.... Just use split bolts and rubber tape then plastic tape....

NEC requires splices to be in a box.... Just use wire nuts and appropriate box.....

I'm not sure you can use wire nuts on 2 AWG THHN proper connection would be a butt splice crimp connection.

Not allowed, use a box.
