Problem with adding new cable type

I have to add another cable type (P1-#2) to the ACRS_CABLE_TYPE table. I have verified that the PERMISSIBLE_SEGR_CODES data matches the tray I am routing it through. The problem comes when running a "Raceway-Regen," I get this error for all cables of this new type:

2013-03-21 08:38:05 NO NEC TRAY FILL RULE FOUND, Cable=1P630-1G, Cab Type=P1-#2, Raceway=1TP008

Got any ideas on how to fix this?

It sounds like a table might have some conflicting, erroneous or missing, data.  The program is searching for the correct set of NEC rules to use based on the cable being routed and the raceway it's being routed through.  The rules consider the whether the cable is single or multi conductor; the voltage class of the tray; the tray type (Ladder Solid Bottom); and the conductor size.

Hope that helps!  If not feel free to email one of us from the contact page or you can call the office directly if you're still having issues.

Based upon your comment that the warning occurs when a rege/resize is run, I am guessing that you had cables routed at one time using a different cable type. Then you added the new cable type and changed one or more of the routed cables to use this new type.  I am also guessing that the new cable type has a conductor size which is not defined in the project data table.  Please refer to the Cable Roting Primer (under main menu help), paragraph 3.3.

Another possibility is that the cable is single conductor and the tray type has a solid bottom and the cable is not triplexed.

I have checked the conductor size, it is listed as #2. #2 is listed in the project data table. The cable is a single conductor, although all of the tray is TRAY LADDER 6H, not solid. I tried changing one of the cables to a different cable type, and on the regen/resize that cable error goes away. So I am still lead to believe something is wrong with the "P1-#2" cable type.

Hmmm... I know that Stanley has their own method of placing the databases on an FTP and supplying us with the access to them vs. the standard GSN FTP method.  Is it possible to upload the databases so that I may look at that them.  If not, another option would be to export the 'Service Level' and the 'Cable Type' tables into Excel format and emailing them to me; though a database would lead us to the problem quicker.

Without seeing the database I would guess that the mixture of cables in the tray in question is not allowed based on the rules of the NEC.  For instance a conductor size that is greater than or equal to 1000 being run in the same tray with smaller cables...

I am having a similar problem. I have a coax cable and am getting the message "NO NEC TRAY FILL RULE FOUND, Cable=I-YIC-8A, Cab Type=RG6U-MC, Raceway=TP-003/I"  I get the same error whether I put "18" or "coax" into the "conductor size" field in the ACRS_CABLE_TYPE table. The tray has a divider and a specific size has been assigned (i.e. P-6/I-6). Fiber optic cables are also routed in the tray.

The first thing that needs to be looked at is how many conductors does the Coax cable have in it according to the cable types table?  If it is saved as a 1 conductor now, change it to a 2 conductor cable; counting the foil and the stinger separately.  

Because the foil and the stinger are 'Landed' in different places in the field, the program has to know about both of them.  This should clear up the problem.

Indeed. Thank you.
