For starters, "Polaris" type connectors are fairly chunky creatures, with a 3-port, 4-14AWG splice taking up over 2.5 in 3, far more than a wirenut or even a push-in type splicing device would use. The other factor in play here is that with either route you take, you'll want to use something larger than a typical 4 or 5" square junction box to house the splices. This compares favorably to having to get three insulated mechanical connectors at around $20/piece at the time of this writing, and also provides a neater installation as the PDB gets fastened to the back of the box so that nothing can flop about. Under these constraints, the cheapest option would likely be a Mersen/Ferraz MPDB63163 with a trio of MPDBC6263 covers depending on where you shop, you'll be looking at about $40-$50 for that, which takes care of both hots and the neutral in one go. What you're looking for is also, aptly enough, called a power distribution block however, in mains-wiring-land, you need to be careful not to confuse them with power terminal blocks, as you must use a part tested and listed to UL 1953 (QPQS category code in the UL database), not a part that's only been component recognized under UL 1059 (XCFR2 category code in the UL database). Fortunately, there is an analog in the mains world to the distribution blocks you're used to in the automotive world. While Ed Beal's suggestion of "Polaris" type insulated mechanical lug connectors will work, it's a bit ugly to have big honking connectors flopping about in a box. Would they or the split bolts need to be secured to the inside of the box, if used?Īny additional suggestions or recommendations are welcome. 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)?Īnother option I found are Polaris connectors. Is there something like this in the home-owner world? 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. 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). 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). For help with product selection and use, consult your on-site safety professional, industrial hygienist, or other subject matter expert.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.
