Conductor Naming and Continuation

General

In Elecdes all line segments are considered to be potential conductors. This is explained in the section, How to Generate Connection Schedules.

A "network" of line segments is defined as "a set of physically connected line segments on your diagram".

A user defined wire name or cable and core (conductor) name and specification is assigned to a network of line segments by placing a wire marker or a cable core (conductor) marker on one of the line segments in the network. If there is no wire or cable core (conductor) marker, then the line segments are considered to be an unmarked conductor, described below.

Unmarked Conductor Naming

During the interconnection analysis, EBASE will assign default numbers to all conductors. If any wire or cable core (conductor) markers are present, on any conductor, then the default conductor name will be replaced. Conductors that do not have an attached wire or cable core (conductor) marker will not have any catalog information. They will retain the default conductor name and be placed in the panel wire schedule.

Unnamed conductors are assumed to be panel wires.

These are also referred to as internal wires in EDS.

The default conductor name is composed of a six digit number, unique for each identifiable conductor found in the project, enclosed in curved brackets: "(??????)", e.g. (000123).

Wire naming and continuation

Elecdes supports wire continuation across line segments which are not physically connected on your diagram. For example, a wire can be "continuous" across 2 or more sheets. There are two modes of wire naming that can be used to represent continuity of physically disconnected wires (or wire networks).

  • The first mode allows all wire markers to cause continuation of a wire.

    Thus any network of line segments with a wire marker with the same wire name is considered to be part of the same conductor.

    In the first mode, wire extension markers have no functional difference from standard wire markers. They provide only a different visual appearance.

  • The second mode allows only wire extension markers to cause continuation of a wire. The second mode is the default mode.

    Thus another network of line segments with a wire marker with the same name is not considered to be part of the same conductor - unless a wire extension marker joins them.

    Wire extension markers are sorted into alphanumeric order by drawing or sheet, then position. They are then joined in pairs from that sorted list. The pairing of wire extension markers can be controlled explicitly. This is described below.

The wire continuation mode can be changed from the Elecdes preferences for cables and wires.

If the second mode is chosen, then each different wire with the same name is identified by a unique network value in the report.

The second mode is very useful when multiple panels are "cloned" in a project and wire numbers are common in each panel.

Wire naming rules when "All wire markers can be continuations"

  • If a wire passes through any device (which could change the voltage/ current signal or disconnect it), it should be given a new name.

  • If a wire passes through a terminal strip then the wire name can remain the same but a suffix should be appended to clarify that the wire has passed through a terminal e.g. W001 [terminal] W001/1. Adding the suffix ensures that for Elecdes they are considered to be different wires, however visually they are seen to be related.

Wire naming rules when "Only wire extension markers can be continuations"

  • If a wire passes through any device (which could change the voltage/ current signal or disconnect it), it should be given a new name. If you break this rule you can optionally receive an "invalid equipotential warning".

  • If a wire passes through a terminal strip, then the wire name can remain the same. Elecdes will consider the wire on the other side of the terminal strip to be a completely separate conductor.

    Ebase will assign a unique network value to each different wire that has the same name.

Explicit wire extension marker pairing

Wire extension markers can be explicitly paired with other wire extension markers by specifying a unique wire network. It is only necessary to dictate the pairing of the wire extension markers if the same wire name is used for different wires.

The wire network value (a number, of string of characters) is entered into the WIRENET attribute of the wire extension marker. This attribute can be added to existing custom wire extension markers that were created for previous versions of Elecdes.

Specifying a unique wire network across multiple wire extension markers

Each different wire is assigned a unique wire network value. The same wire network value should be entered into the WIRENET attribute of all of the wire extension markers on one wire.

When the same wire network value is used for each wire, it is not necessary to have an even number of wire extension markers (in pairs) for each wire. Every wire extension marker that has the same wirename and wire network value is considered to be connected.

Wire network values can be re-used only on wires that have different wire names.

Cross references for the wire will refer to a reference list that is placed, by default, next to the first wire extension marker.

If different wire network values are entered for one network of line segments that is physically connected on a drawing, Ebase will optionally report "Inconsistent wire network" in the WARNINGS column of the various wire schedule reports.

Explicitly joining each pair of wire extension markers

Each pair of wire extension markers that is to be joined is assigned its own wire network value. A different wire network value should be entered into the WIRENET attribute for each pair of wire extension markers.

Wire extension markers must exist in pairs.

Wire network values can be re-used only on wires that have different wire names.

Cross references for the wire will be made between each pair of wire extension markers that has the same wire network value. There will be no reference list.

Different wire network values are used intentionally on one wire, therefore the warning "Inconsistent wire network" must be disabled as it offers no useful information. See information about disabling warnings.
