Will splice cause voltage drop?

I'm about 10 feet short on my 200 foot run of #6 aluminum wire feeding a subpanel. I only need 25 amps but I'm worried that if I splice on the 10 feet that I need that I'll have too much voltage drop.

Any need for worry? How is the best way to splice, with copper or stick with aluminum?

The voltage drop due to a splice should be negligible if done correctly.

Use a splicing means that is compatible with AL conductors.

I agree with nap and joed both.

If this is direct burial cable you can get a direct burial splice kit for it.

If it is conduit you MUST have the splice accessible in a junction box. You CANNOT splice inside conduit
