Thats what I just installed monday.Decided to go with these inside appropriate box types for wire transitions (solar wire to MC) and splices. Seemed simple enough, reusable and designed for the purpose.

I got lucky on this since I was combining the small wires from the power supply on the orange pi 3 lts thats running solar assistant and the power for the surveillance cameras and such.I could not find kits for the DK6N only the DK4N. The DK6N does 8 awg, the DK4N does not. I needed up to 8 awg
Right approach, as long as you check on them periodically. Personally I have seen miserable safety results in the past with crimp or set-screw butt splices. The only thing we ever allowed was compression butt splices on 4/0 or larger; we replaced small wires.Decided to go with these inside appropriate box types for wire transitions (solar wire to MC) and splices.

I'm assuming "mechanical" also means the connection point at the breaker ?Right approach, as long as you check on them periodically.

Mechanical splices have a way of being forgotten and working themselves loose. This is especially true for connections that cycle from zero to a continuous >60% load daily.
Even for high voltage DC? (or does it AC / DC even matter)Box and wire nuts are perfectly fine.
When I first came to the USA, wirenuts frightened me to death and made me laugh all at the same time but over the years I have come to appreciate them immensely. Done properly they are one of the safer connection methods available.
The breaker connection is generally easier to inspect though. Few places inspect splices unless they have had a problem with them.I'm assuming "mechanical" also means the connection point at the breaker ?
If they are made up properly it won't matter. But, if they are loose or have eccentric strain then internal arcing seems possible and higher risk with DC IMO. I don't think voltage matters much below 600V.Even for high voltage DC? (or does it AC / DC even matter)
