Splicing on Sub Feed Conductors

Hello, TN Licensed Home Inspector here.

We recently came across a 6/4 electric conductor routed through an attic space which was spliced at two different locations within two separate junction boxes. This conductor was servicing an electric sub panel at the rear of the house.

This seemed like an unusual amount of splicing on a large gauge conductor which we do not typically see, but we were unsure if this was a reportable issue. We noted the condition was "not typical, could be further evaluated".

My question is, are there any issues regarding splicing larger gauge conductors feeding sub panels which would result in a notable loss of power/ohms/amperage?

If these splices are acceptable, is there a maximum amount of splices which can be used on larger gauge conductors servicing sub panels?

Thank you,

As Tom stated there is no limit and with two splices in a single feeder there is nothing that should be mentioned in your report.
 
Proper size box? I came behind a carpenter that spliced 6-#6 thw in a 1 1/2” deep octagon box using Kerneys! He managed to get the cover on, but one of the kerneys shorted against the ungrounded box, energizing the nails that pierced the foil sheathing. The gas guys weren’t overly thrilled about getting shocked when they drilled a hole through the siding. LOL!
 
Yes feeders get spliced all of the time. In commercial work it may be necessary to splice a single feeder 3 or 4 times if the length is great and there are lots of bends in the conduit run.
