A lot of professional audio gear uses 5.08mm connectors. I bet WAGO makes some of them!
But be careful with NM-B cable. I didn’t find an exact reference in the NEC, but I bet that Article 200 and friends would not approve of the reuse of the bare conductor for anything other than ground and might also disapprove of using the white conductor for anything other than neutral. (If you’re not installing the cable in the wall, maybe it’s not subject to the NEC.)
Get some nice TC cable instead.
- rsync 3y agoI wonder if we're misunderstanding each other ... I am not suggesting you dual-use your high voltage romex and also send audio signals on it ... I am suggesting you run additional runs of romex dedicated solely to audio. This would be NEC compliant.
- amluto 3y agoWould it? You’re allowed to use chapter 3 wiring methods for audio, but two speaker circuits is four “ungrounded conductors.” Red and black are fine for this purpose. I’m not so sure about white and bare.
- donor20 3y agoCan you tape the ends red and black in this case? I thought there were some provisions for options there in case you had some super heavy cable but wrong color
- amluto 3y agoThe rules are different for <=4 AWG wires versus smaller wires. I don’t know why.
- sokoloff 3y agoYou can use tape or heat-shrink to re-identify a wire if its 4 AWG or greater or if it's part of a multiconductor cable (which NM-B is). The reason for the 4 AWG rule is probably an economic one. Having spools of larger conductor cables in a variety of colors is not inexpensive. Allowing the reidentification seems reasonable, though I'd probably argue the cutoff could be thinner than 4. The multi-conductor cable exception is a practical [and economic] one. You might not be able to get multi-conductor cable assemblies with the exact color coding you need.
- donor20 3y agoAhh - makes sense - high amp cables get insanely expensive
- epcoa 3y ago> using the white conductor for anything other than neutral. Where the NEC applies, you can use the white conductor in a multiconductor cable for anything as long as it is "permanently reidentified", that is color coded where it is exposed. cf NEC 200.7.
