General Field Wiring Guidelines

22.5.1.1 General Guidelines
Make sure these guidelines are accounted for before wiring:
• All wires must be 18 AWG, or as the local code dictates.
• Conductors must test free of all grounds.
• All wiring must be done using copper conductors only, unless noted otherwise.
• If shielded wire is used,
- the metallic continuity of the shield must be maintained throughout the entire cable length.
- the entire length of the cable must have a resistance greater than 1 Megohm to earth ground.
• Underground wiring must be free of all water.
• In areas of high lightning activity, or in areas that have large power surges, the 2081-9027 Transient Suppressor should be used on
monitor points.
• Wires must not be run through elevator shafts.
• Wires that run in plenum must be in conduit.
• Splicing is permitted. All spliced connections must either be soldered (resin-core solder), crimped in metal sleeves, or encapsulated
with an epoxy resin. When soldering or crimped metal sleeves are used, the junction must be insulated with a high-grade electrical
tape that is as sound as the original insulating jacket. Shield continuity must be maintained throughout.
• A system ground must be provided for earth detection and lightning protection devices. This connection must comply with approved
earth detection per NFPA780.
• Only system wiring can be run together in the same conduit.
