These blocks are a much nicer option than the standard "bus bar." Each of the 20 positions is well numbered (both below and above) where the wire inserts so you're probably not going to mis-connect a conductor. The screws for tightening down on the conductor are as expected a standard screw driver. A 10 gauge wire easily fits in the terminal blocks points. The other thing that I really like about this block for an ac distribution is that it's going to be pretty hard to shock yourself because all of the metallic points are either recessed or mostly inaccessible. I bring this up because several previous boats which I have worked on had the typical open faced terminal blocks which you could (in a tight space) brush up against and shock yourself. Overall, this is a nicely executed product and I am glad to have used it on my sailboat.
