I have a situation where my oven and counter-top range are split up, but fall within spec of being able to utilize one 50a breaker on the panel.
My plan is to pull a single 6/3 cable to a large junction box, inside which I’d splice the two sets of 8/3 wires from the oven and range with the 6/3 cable (hots and neutrals, the grounds are skinny enough to use a twist-connector). Because the all the cables combine to be pretty thick, I am not sure a twist-connector on the hots/neutrals would be a good choice (previous owner had it that way, but even with smaller cables it felt a bit sketchy).
With NEC 2017 in mind, what type of connectors can I use? In the automotive world I’m used to things like a multi-terminal connector/distribution block. Is there something like this in the home-owner world?
Tried searching and found some split-bolt suggestions - do I just wrap it with lots rubber tape to insulate? Can a split bolt be used to connect three wires (one 6ga and two 8ga or even just 3 6ga if a future oven has that)?
Another option I found are Polaris connectors. Expensive but seem straightforward. Would they or the split bolts need to be secured to the inside of the box, if used?
Any additional suggestions or recommendations are welcome.
