    Hi R T,
    The amperage ratings for the conductors you have described are comparable so that should not be a problem as long as the insulation ratings are alike as well. NEC 312.8 speaks of splices and taps being permitted inside panel boards and cabinets, as long as they do not take up more than 40% fill. Based on this, I don’t see a problem, just make sure to use approved splicing methods and identify all of the spliced conductors properly.
    I hope this helps,

    I have 2 #4 cables that I wish to place under a 00 circuit breaker. Can I use a short 00 cable and insulated splices for the 4? This would be in the main disconnect panel.
    Room is not a problem but can I make splices in the main panel?
