9.1 Trays
A tray is an electrical raceway that has at a minimum service level, raceway type, length and from
and to nodes. The From Offset field should be left blank. When the size lock is not ‘Y’ ,
CableMatic will size the tray and select the raceway catalog number according to NEC rules. The
user may change the raceway catalog number but that value should be consistent with the
raceway type. To ensure that the data is consistent, select a value using the F3 key pull down.
CableMatic can also store an accurate geometrical path of the tray. This type of data would be
imported from a 3D application. Utilization code may be used to keep cables from automatically
be assigned to the tray during automatic routing. The rule is that if a raceway has a utilization
code, then a cable using it, must have the same utilization code. From and To Location is printed
on the tray fill report. CM+ supports separators for the trays. See Using Tray Dividers or
Separators in the help menu.
9.1.1 From and To Points
The From and To points on Trays create a connectivity network between trays that enable
automatic Cable Routing. When designing trays in TrayMatic, From and To Points get entered
automatically by updating (synchronizing) CableMatic data with TM data. The format and the
naming conventions of the From/ToPoints are as follows.
The From point of a tray is on the side of a Tray that has the lower X, lower Y or lower Z location.
The To point is the other end of the tray. If a tray does not connect to another tray, the node point
will be named <tray name>:A or <tray name>:Z respectively.
Eg.: TC-001:A, TC-001:Z
If the tray connects to another tray or list of trays, the tray with the lowest name (alphabetically) will
be used as a node name, followed by “:”A” or “:Z”. That node name will be listed on the from or to
side of every tray connected.
If the project does not use TrayMatic, the user will use the ACRS_TRAY_END_CONNECTIVITY
table to enter the connecting tray ends himself . After that, run Advanced Tools->Process Tray
Connectivity List to update the From/To points.
9.2 Guide Conduits and Duct Bank Conduits
A Guide Conduit is a virtual conduit that represents a group of embedded conduits that follow the
same path. The idea is that all cables following that path can be routed (temporarily) in the Guide
Conduit without restriction to overfill or service level segregation. CM+ will report fill by the cross
sectional area of cable for each cable segregation code and therefore you can decide how many
conduits to input for each service level. When entering the Guide Conduit, use ‘00’ for the service
level and ‘GUIDE CONDUIT’ for Raceway Type. Utilization code is used for the duct bank
conduits to “force” cables into specific conduits. The rule is that if a raceway (or duct bank
conduit) has a utilization code, then a cable using it, must have the same utilization code. Data
required is the same as for trays (service level, raceway type, length and from and to nodes).
9.3 End Run Conduits
An end run conduit is an electrical raceway that has at a minimum service level, raceway type,
length and ‘From’ and a to node (should be an equipment tag). An end run conduits may leave a
tray at an offset or leave a tray or other conduit at a node. The ‘From’ may be a node or a tray.
When the ‘From’ is a tray, you must enter a ‘From Offset’. The ‘From Offset’ may have several
input options:
1) If a number is input, then that number is the length in feet from the ‘From node’ of the tray that
is in the ‘From’ field.
2) If a percentage is entered then that percentage is the portion of the length of tray in the ‘From’
field as measured from the ‘From node’.
3) To measure from the ‘To node’ of the tray in the ‘From’ field, input the node number followed
by a ‘\’ and then either a length in feet or a percentage.
When the size lock is not ‘Y’ , CableMatic will size the conduit and select the raceway catalog
number according to NEC rules. The user may change the raceway catalog number but that
