Tray Cable/ IT room floors - 04/25/05 11:43 AM
2 Questions.
1. 645.5(d), type mc cable can be used in raised floors in IT rooms.
Is this right? I thought it all had to be liquidtight.
Or am I missing the section somewhere that if water lines are under the floor, it all has to be liquidtight.
2. Where do I find where Thhn is cable tray rated? I was at a lumber mill the other day and noticed what I thought was 500mcm in cable tray. Single conductors, not tray cable.
Any help appreciated.
