feeders may be too short
Considering replacing subpanel. There is 3 wire #8 thhn going to it but putting in a new panel, with different configuration of enclosure, I am thinking its possible the new feeders will be a bit to short.
Can I splice/extend the wires of the feeders?

Also, what size is the breaker that protects this feed?

Cable? If so, is it 8-3/G (2 hots, 1 neutral and 1 ground)?

Its not cable. Its in rigid. You already knew that though otherwise I would have said it was 8/3 with ground. Its protected by a 40A breaker and 2x20A in the subpanel.
You bring up another concern. When am I able to splice in the panel?
For example, one circuit controls a few outlets and the other controls a few ceiling lights. Those devices are wirenutted in the subpanel and pigtails go to each breaker. The returns are also pigtailed the same way. Is that code compliant?

Which THHN are you missing? You need 4 wires, hot, hot, neutral, ground. You may need to run one more in the conduit. "When can you do it"? As soon as the power is removed. Splicing within the subpanel is compliant.

The conduit is the mechanical ground. Im not asking about a new installation here.
Splices can be made in the panel.

A double pole 20 is not a 40 amp breaker. It is a 20 amp breaker.
Splices can be made in the panel. I might just pull new #12's instead of splicing.

Also, it sounds like there are just 3 conductors in the conduit and the conduit provides the path to ground. If so, is it bonded at both ends? Also, since this is a subpanel, are the neutrals isolated in it?

The breaker in your main panel and the feeders are both sized for 40A. The breaker in this subpanel is limiting it to 20A. Is there a reason for that?

And since your asking, the conduit is bonded. The EGC bus is bonded to the enclosure which is connected to a ground rod. The neutral bus is not bonded to the enclosure.
And since we got on the topic of 3 wire vs. 4 wire.... I wonder how does grandfathering play into this? I think that 4 wire was a 2008 change correct?

It is not a double pole breaker and their is no main in the subpanel. There are 2 separate 20amp branch circuits serving the structure (detached garage) which is wired with #12.

I'm not sure about the others, but I don't volunteer my time to be berated by someone like you. Not all installations have continuous rigid, thus the grounding effect is not there. You don't need to come back at us with quippy remarks when it is you who is seeking advice.
You asked about splicing in a panel. I answered. It wasn't what you wanted, so you had to make a smart remark. Keep your comments civil, please. You may get better answers that way.

Pete, you've been a member here for a few months now. I assume you've long since read Electrical Forum Rules and Policies [PLEASE READ BEFORE POSTING], but this might be a good time to read through it again - especially the last section.
In fact, anyone who hasn't read it, or hasn't read it in awhile, would probably benefit from reading it.
BTW, Pete, you might have thought that Chandler was teasing you with his question. He wasn't. If he ever does decide to tease you, I promise you'll know it. And regardless, you could have asked.
