Splices

Yes keep in mind the 6X or 8X rule for the splice box if the conductors are #4 or larger.
 
Gentlemen, Thank You for all the helpful information. Much appreciated! On this same job the inspector ( Taylor MI ) is requiring a disconnect switch mounted outside. I am searching for that language and cannot find anything that says I need a separate disconnect after the meter. (The panel has a main Breaker) Any ideas?

230.70(A)1.
Maybe someone will have better answer when you need to install outside disconnect if panel is too far from point of entrance min. Feet distance

New requirement in the 2020 NEC.

It appears you are splicing service conductors and not feeder conductors.

NEC limits distance service entrance conductors can enter a building - yet doesn't give a distance and this leaves it up to individual AHJ's to determine what they will accept.

Most places have at least allowed service disconnect mounted on exterior wall with service conductors going directly outside.

Now as mentioned 2020 NEC requires an outdoor emergency disconnecting means on one and two family dwellings, it doesn't necessarily have to be rated as service disconnecting means though and there are a few ways it can be done depending on conditions, and maybe some questions remain on what is allowed - I sort of expect some changes next cycle to clear up some questions here.

Where are you getting that from? Looking at 314.28, I don't see a difference on the 8x whether it's spliced or pulled through.

Thanks.

I think the code was written for pulling purposes the splicing would pertain to box fill calculations.

There is no box fill calculation once the conductor size is #4 or larger. Table 314.16(B) ends at #6 AWG.
 
Still for pulling purposes,

Old saying goes six for tricks eight for straight.

You can need more room for a straight through pull than is needed for other possibilities
