You are placing Category 6 unshielded twisted-pair (UTP) in cable tray down a hallway past the elevator mechanical room. What action should you take to avoid effects of electromagnetic interference…

Per ANSI/TIA-569 and BICSI TDMM guidelines, a minimum separation of 1194 mm (47 in) is required between unshielded copper cabling and high-power EMI sources such as elevator motors and associated electrical equipment. This distance is sufficient to attenuate the magnetic field intensity to levels that will not induce noise into the UTP signal pairs. Maintaining this clearance avoids the need for shielded cabling or conduit in most hallway routing scenarios.

2060 mm (81 in) far exceeds the standard-specified separation distance for this scenario and is not a figure defined in TIA-569 or BICSI separation tables for elevator motor rooms.

Requiring architectural modifications such as metallic foil wall shielding is outside the scope of a cabling installer's responsibilities and is not a recognized solution in BICSI or TIA cabling standards for EMI mitigation.

RMC/IMC provides mechanical protection for cabling but is not required throughout all areas within 4.6 m of an elevator room solely for EMI mitigation - proper separation distance is the primary prescribed remedy.
