Anandtech electricians need some advice

So much misinformation. You can have 2 hots and one neutral as long as they are on different legs. If they are different circuits, but same leg, then no. Also, if you share a neutral, they must be on the same breaker (two pole). Lastly, if you have two hots from different circuits, but the same leg, you will not get 220v between hots. You will instead get 0v.

Doh! Left out the most important part. If you have 20 amps on one of your hots, and 20 on the other, the shared neutral will have 0 amps, not 40.

Aren't sine waves wonderful?

Oh right I guess the thicker stuff like Telcoflex #2 and stuff would be considered standed. I always still considered that solid, as the "strands" are very thick but guess it's still stranded given it's not just one big strand inside. Just never seen any "building" rated #12 or similar residential sizes stranded before so that's why I was surprised.

Maybe the confusion came from mixing up cable assemblies and wire. Telcoflex, Teck, MC, and Romex are cable and meant to be installed on their own, barring rules about physical damage and weather resistance. 'Wire' is a different beast and is meant to be installed in raceways or tubing. If you google THHN then you would be looking at the most common wire installed in those raceways.

Granted, THHN is just a descriptor of the insulation and comes in solid and stranded conductors, but in the trade it is assumed stranded because if someone says THHN, it is implied that you will be putting it in a raceway and stranded is preferred in this application.

If we are talking AWG, then #6 is the largest solid conductor I have seen, it has all been stranded larger than that. I have only personally dealt with 1500 kcmil wire, which was stranded, in aluminum only.

I disagree. I covered the conductor type misinformation, and master_shake took care of the MWBC misinformation.

i went ahead and pulled the extra ground instead of bonding all my receptacles.

Good call. We always do the same, no point relying on cheap connectors staying tight and the EGC doesn't count as a current carrying conductor in pipe fill derating anyways.
