I'm going to be installing a switch and 40 workstations/printers in a building. All the rooms have raised floors with cable trays running in various grids and there are cable trays going between the rooms accessible from the basement. Most of the runs will be between 200' and 300'. All the runs will be going from the switch in the computer room, under the floor in cable trays and then popping up and directly connecting to the workstations/printers.

I remember back in the day it was a big deal to use solid cable for horizontal runs but that was usually between a switches or other stationary devices. I've been seeing problems with similar situations where a solid cable was used because people move stuff around and eventually the conductors break.

Now in the modern day does anyone see a problem with using stranded cables for this type of installation?

Use solid core wire for structured wiring (in-wall, above ceiling, etc), it's cheaper.

Use stranded core wire for everything else (eg, wall to computer, in-rack, patch panel to switch, etc)


To directly address the question as stated:

I remember back in the day it was a big deal to use solid cable for horizontal runs

That makes no sense at all - whoever made this a big deal was uninformed at best.

that was usually between a switches or other stationary devices

As stated above, solid core is for structured wiring, not "stationary devices" which have a tendency of moving over time. It should only be used where the endpoints are part of the building.

I've been seeing problems with similar situations where a solid cable was used because people move stuff around and eventually the conductors break.

Correct - which is why you never use solid core outside structured wiring.

Now in the modern day does anyone see a problem with using stranded cables for this type of installation?

You never cited any actual problems with using stranded core cabling in the first place. The only reason it wasn't used for structured wiring is price, stranded is more expensive than solid core.

Nice canned answer but it doesn't answer the question. How about from switch, under floor, up from under floor and directly to computer? I don't have the option of a wall connection. –  murisonc Apr 4 at 20:43
    
Yes, it does. That's not structured wiring, so it's in the "everything else" bin. Also, I'd recommend not doing that in the first place. –  Chris S Apr 4 at 20:48

+1 I can't tell you how many times I've seen solid-core terminated in RJ45 plugs, directly to the server. That is not a good situation, for many reasons. –  EEAA Apr 4 at 20:52
    
@murisonc You really should reconsider your no-patch-panel situation. –  EEAA Apr 4 at 20:53

Ok, I get what you mean. Unfortunately I don't have a choice because of the way everything was setup 15 years ago. They won't let me put a patch panel in each room. Typical Government craziness. –  murisonc Apr 4 at 20:55
