Analog Circuit Wiring Requirements and Limitations
1. Cable length per circuit - 4,000 feet maximum including all "T-tap”
runs. “T-Tap” wiring is not allowed on signal circuits.
2. Use twisted cable wherever possible, even when in conduit.
3. Twisted cable required on all open wiring runs involving 1,000 Ft. or
more.
4. Avoid running circuits parallel with power wiring for any distance.
5. Avoid running circuits parallel with cables having high switching rates.
6. Avoid running circuits parallel with fluorescent fixtures.
7. Avoid running analog circuits parallel with signal circuit wiring.
8. Shield signal circuit wiring , even if in conduit, if run together with
analog circuits.
9. Maximum conductor resistance for circuits is 25 ohms.
