Question about symbol on plans

In the attached pic there is a receptacle that shows it is on circuit #12. Then it shows that we'll be pulling circuits 10,12,14 to the receptacle. Am I just looking at this incorrectly? Does it mean something else?

Thanks

I agree with Mac, a 3 circuit home run and you branch out from that receptacle box with the other two circuits.

These days, no common neutral?...

That was my first thought, too. It's been a LONG time since I used plans on new construction, but I think the symbols mean three hots, three "neutrals," and a ground? Makes me wonder what the benefit is unless this is in conduit (term includes EMT...) and they are saving pipe.

I saw three neutrals! I thought we were trying to save the planet. Now, more wire is being used, not less!

Are ckts 10 and 14 nearby? It looks like a 3-ckt homerun to me, and then the other two will go from there to ....

Thanks, that's kind of what I thought (and am used to) but one of the circuits is a good distance away in another room so it didn't seem correct. I guess it's possible the architect and I have a different idea of how the circuits should be run.

I've been on some jobs where I was allowed to do it my way, and reflect it on the as-builts. I've been on other jobs where I had to do it their way.
 
sometimes the way the engineer denotes a homerun on your power prints makes more sense when you check how the circuit is identified on the panel schedule.. which is a great way to find out it may be a mistake, or correct. or, even realize it may be the wrong panel. i have learned the panel schedule is, in the end, the absolute of what you are selling the customer, regardless of discrepancys on the power prints. however, the number and location of actual power outlets are absolute... err- usually! always dble check all your sheets, especially when it comes to your equipment schedules on the hvac schedules.

+1 great advice.
Oh, 3h,3n.
 
I always call the engineer or architect and get clarification and see if you can wire it your way. I would not want all those circuits run into a receptacle. Maybe a jb above if you have a suspended ceiling but not to the receptacle.

With the common disconnect requirement for MWBCs in 210.4(B), it has been a long time since I have seen an engineered set of drawings that permitted multi-wire branch circuits.
 
I think if you did happen to call the engineer his reply is simply going to be ,,,,, "OOOOOOPS".

We are going backward. Spending more on resources to do the same task.
A common neutral was good until it wasn't...
I don't fight them anymore, just pass the cost on to the public...

You now have three wires in that conduit that we didn't have years ago. That includes the ground wire if this is an EMT conduit.

What a total waste of copper, conduit (increase in size), and labor.
