Does wire splice matter?

I just had my load center moved by a licensed electrician. The original location was in a closet on an interior wall with lots of attic access above it, so the electrician was able to pull the old wires out of the old load center and feed them into a large junction box mounted above the old load center in the attic. For most of the circuits, a cable was run from the new load center breaker to the new juction box (about 20 feet), and the new cable was spliced to the original cable in the juction box for each circuit done this way. The splices were done by twisting the conductors together, then using a wire cap. In this area, the inspectors actually allow the splices to be made in the old load center (after it is "gutted") but it was easier to do it in the new junction box.

The circuit I'm mostly concerned about is the standalone circuit for the electric wall oven. It's a 10/3 cable on a 30amp double breaker. The cable is about 90 feet long. Should I be concerned that there is now a splice in that cable about 20 feet from the breaker? Does a splice affect the load capability of the cable in this scenario?

Also, should I be concerned about the kitchen countertop circuits having another splice in them now? They are all 20amp circuits using 12/2 cable with runs of about 100 feet.

Thanks,
Ira

Correctly done splices are not a problem. It sounds like they were done correctly unless you had aluminum wires.

Everything on my side of the meter is copper.

Thanks,
