When planning for cable routes, we consider any obstacles within the route and identify the best practice for signal separation, pulling tension and bend radius.
Best practices we follow:
- Signal cables should be routed in a completely alternate path from power cables.
- Use rigid, metallic conduit for signal cables when nonmetallic conduit (PVC) is used for the power or when power and signal cables are close together over a distance.
- Do not put microphone cables and speaker cables in the same bundle or conduit.
- Keep voice lines separate from data lines to avoid spikes and data clicks in audio.
- If there is only one conduit, do not mix high level (line or speaker level) and mic level signals.
- When planning a cable route, keep your signal cables as far away as possible from sources of electrical noise; fluorescent lights, transformers, motors, elevator relays, radio transmitters for burglar alarms, and similar sources of noise.
- Install pull boxes every 100 ft or 180 degree of bends
