Recommended Wiring Practices

General rules
Wire bundling
98
• All wiring must conform to local codes and practices.
• Wires carrying similar types of signals (Table 9-1) may be bundled
together, but bundles with different types of signals must be kept
separated to prevent inductive or capacitive coupling.
Table 9-1 shows what wiring should be bundled together to prevent
inductive or capacitive coupling.
