.....sure, sometimes you need to do some trimming to make 12 or 10 ga fit comfortably in a connection if you're not using a banana plug, which I don't feel are necessary at all....what I feel best doing is removing/cutting/stripping the insulating covering back about one-half to three-quarters of an inch, and then flair the outside individual wires leaving the inside core of about 1/3 of the individual wires standing straight up....then I snip the 1/3 of the individual strands left standing up at their base where the covering begins, and then raise back up the outside ring of indivdual wires and twist....the inside 1/3 of the individual wires beginning at the point where the covering is stripped back to, is then encased by the outside ring now reduced to fit the connection.....think of it as looking down on a dime, and with a wave of the magic wand, the middle third is removed, and the outside ring left reduces to fill the hole.....it's really not necessary to do this, but it's just something I feel better about....if this is clear as mud, I'll try again.....
