Probing inspectors minds

Im not an inspector.
I havent seen an inspector question a panel with or without handle ties.
Seems its more work that its worth to prove they needed to be used, plus if theres an issue the EC will be getting the call.
I have too much trouble finding them plus it used to be cool to pull 3 hots and a neutral , itll start a riot these days.

Well, Bill Kriegh is correct that a MWBC is a single circuit, the rest of the thread is to scattered to talk about, is there a specific question?

In this thread - not really

In the one linked to - The OP seems to question whether handle ties are needed for a full boat MWBC and if the code even allows them for such MWBCs.

In recent editions of NEC you must use either approved handle ties, or a true common trip multipole breaker for MWBC's. Either option meets the requirements for disconnecting all ungrounded conductors of the circuit simultaneously.

MWBC's are not required to trip all poles automatically just to open all of them when manually switching the circuit off. Even a MWBC supplied from a fused safety switch fulfills the requirement - one fuse can blow independently but all poles are opened when operating the switch.

While I appreciate your post, I was merely answering Roger.

Derek, what I was asking was, is there a part of that train wreck that was a specific question or does the OP just want to ask the original question here.

My bad for quoting you instead of just posting what I had to say - I was not disputing or asking for more about anything you specifically said. I need to find different practices I guess as I quote things to remind me what was said or what it was that triggered my though process while composing sometimes but is often taken as criticism of what was quoted, which most of the time is not what was intended.

Your post was correct and fine, I did not feel you were criticising me, it was simply that I did not post the original question.

What I should do is copy your post and post it over at the HI forum. I am a member there, but have not participated in quite awhile.

The original question by the OP was whether or not it is code compliant to use handle ties on MWBC's on a three phase system.

The answer would be yes. SQ D and CH both make handle ties listed for three breakers and I would say others do as well, I just haven't had reason to check the others yet.

I posted the link thinking others might be interested in the absurdity of the negative arguments of some of the "professionals" on other sites. I guess I was wrong.

Not familiar with that site, but not surprised with what was posted either. Seems to be many inspectors out there that are not too open minded and do not want to be told they may be wrong about something. Most that do come to this site seem to be willing to at least listen when something goes against what they think is right.

I will say I only read first 10 posts or so in the thread that was linked to in OP, but thought that if it was a site for inspectors I would have seen an answer similar to what I posted here withing first 10 posts or so.
