Wiring These Receptacles

At a little bit of a loss how I should figure the conduit for these since there are no sharing of neutrals, a lot of separate circuited devices and no specifics on any drawing as to whether these are flush or surface.

1. I don't think it's possible to run the conduit surface mounted horizontally at all. There are tele/data devices in between. In the there area where there any tele/data devices I think there are too many circuits to run one conduit surface horizontally.

2. I don't think I should figure vertically surface either.

3. Only other choice is individual stubs vertically within the new CMU block walls.


What's your opinion?


Thanks.

If you set one box and stub per opening up the wall, you will have more options/flexibility per opening.
 
What about Wiremold at the baseboard? The larger series, like 4000 or 5400, has a split/2 compartment raceway that can house power in one part and communication in the other.
 
I would first look at the architectural drawings to see what they show on the walls and the size of the block. Judging from what i can see it looks as if it is 4 to 6" CMU. If that is the case its going to be pretty tight to get the boxes in the wall but not impossible.

If in doubt send an RFI for clarification.
 
Do spec's say anything about recessed or surface mounted equipment? Just judging from the drawing clips you posted and if walls are new construction, the client wants recessed outlets.

Is there a height specified for various outlets?

Probably best to stub up each teledata outlet. I'd have no reservations about running one stub up and horizontal raceways for the power outlets on one wall, perhaps even around corners.
 
Ok so another question to add to this scenario. If you were running EMT vertically and had to get to a homerun box on the ceiling about 15' away on an exposed ceiling and the spec read that ALL exposed ceiling conduit to be run in RGS would you transition over to RGS with and adapter once your out of the CMU wall and on the ceiling or run RGG right from the receptacle to the HR box?
 
Well if they get technical about it, you cannot come out of the CMU wall with EMT because that would be exposed. So your transition has to be right at the surface or within the wall.

I'd be okay with stubbing up with GRC all the way or use EMT and transition with a GRC 90° elbow at the top coming out... as the installer.
