Help ID this wire please

[curdy]

Hi everyone, hoping someone on here can help me ID this wire that I have. Originally I was going to use it for wiring in a barn but sold the farm. I'd like to sell the wire vs scrapping it since it's good stuff, but will go that route if it's not easy to sell. It has 8 solid wires: 14ga x 6 wires, 12ga x 2 wires (white). I have close to 300 ft of it. I thought it was 3 phase but IIRC someone told me it wasn't.

Thanks in advance for the help.

That is 14/4 super neutral with an isolated ground. Scrap it because no one wants it because no one uses it anymore.

What the heck was the application?

My guess is cubicle connections… its got conductors for 1 MWBC on 3 phase 208Y/120 and an additional set of conductors for a single circuit, giving the quad cubicle set 1 circuit per desk…

Very similar to what someone asked about the other day.

And....this thread is the answer.

Can someone confirm this wiring please?

Made an acquisition today on some standing desks that have built in surge protectors. Am I correct in stating that the way it was wired in the office was on 2 separate building circuits feeding the 4 desk circuits? I didn't have access to the electrical room, but to me it looks like they used...

Why the up sized neutral?

Why the up sized neutral?

Non linear harmonics. Electronics ( specifically the then new electronic ballasts ) caused something of an issue. Oversizing neutrals were thought to eliminate or mitigate the additional loads on the neutral. I cannot claim to truly understand the issue, but I do recall all of the hubbub about it.

Supposedly some fires started in cubicle wiring from the overloaded neutrals. Odd harmonics add in magnitude leading to increased current in the neutrals.

Yup 3rd and especially 5th harmonics will do that..

Here is an explanation of how the harmonic energy adds on the neutral

What are Triplen Harmonics and where do they happen?

The triplen harmonics are the odd multiples of third harmonics.The triplen harmonics orders are 3,9,15,21,.The triplen harmonic frequency
