6. Planning Electrical Connections
6.1. Routing Cables
6.1.1. General
Whenever possible, keep high-voltage and power cables away from any other cables. Use separate trough in duct
system. Minimize cable length between the line disconnect and the system cabinet power unit to reduce voltage
regulation problems and wiring costs. For information about the cables supplied with your system, please refer to
Chapter 8.
6.1.2. Conduit
Using conduit imposes some important considerations when used with this system. Of primary concern, the majority
of cables used are pre-terminated. Pre-termination greatly simplifies interconnection but makes cable-pulling
difficult because of the added dimensions of the connectors. Conduit must be large enough to pass the cable and
connector through with all other cables already in the conduit. Also, the size of conduit chosen must allow for future
growth. There’s the possibility of additional cables being added later as the system is developed and options are
added. The use of conduit is recommended for cables running overhead between rooms, especially when a diagonal
run provides the shortest cable path.
6.1.3. Floor Ducts
Floor ducts have advantages when used with a single room or two adjacent rooms. Floor duct combines cabling in a
neat, functional appearance with accessibility and room for expansion. The disadvantage is the amount of work
required to install it, which is generally prohibitive in existing installations. For the same reason, it is impractical to
attempt to add on to existing floor duct systems.
6.1.4. Power Distribution
The following diagrams illustrate the options for providing system power.
