Wire-splicing and pigtailing within a loadcenter cabinet (panel enclosure) is expressly permitted by NEC 312.8 (A), and is quite safe (provided the splices are made up properly, of course):
Wire-splicing and pigtailing within a loadcenter cabinet (panel
Learn how to install a distribution box safely and correctly. Covers wiring, placement, standards, and expert tips for a compliant setup.
Electrical panels are not junction boxes. Learn why splicing wires inside the main enclosure is unsafe, non-compliant, and what to do instead.
I was told that the distribution panel does not require a main circuit breaker (disconnect). I contend that in order to disconnect the power to the distribution panel, you have to open both the normal and
Wiring arrangement: Arrange the wires neatly in the box, fix them with zip ties, avoid wires from tangling or coming into contact with sharp edges, and reserve a certain amount of space

1) Splices must be made with a wire nut or other rated connector. 2) All wires must be sized to be compatible with the amperage rating of the breaker they are connected to.
In the main panel, the neutral and ground must be bonded by Main Bonding Jumper (MBJ) wire from manufacturer as crossover tie bar, but in sub-panels, they must be isolated. Never connect the
