Applications and Features:

Southwire Armorlite® Type MC Cable Neutral-per-phase products comply with NEC 200.4 requirements (added in the 2011 NEC) for the installation and marking of neutral conductors. Neutrals are not to be used for more than one circuit (branch, multiwire branch, or ungrounded feeder). See NEC 200.4 for complete requirements.

Southwire Armorlite® Type MC Cable - Neutral per phase is suitable for use as follow:

Applications affected by harmonics generated from non-linear switching loads, such as computers, variable frequency drives, electrical test equipment, and office equipment.

Multiple circuits for branch, feeder and service power distribution in commercial, industrial, institutional, and multi-residential buildings.

Fished or embedded in plaster.

Concealed or exposed installations.

Environmental air-handling spaces per NEC 300.22 (C).

Places of Assembly per NEC 518.4 and theaters per NEC 520.5.

Installation in cable tray and approved raceways.

Under raised floors for information technology equipment conductors and cables per NEC 645.5(D) & 645.5(D)(2)

Class I Div. 2, Class II Div 2, & Class III Div. 1 Hazardous Locations.

Binder tape with print legend wrapped around assembly.

Type THHN/THWN rated 90ºC Dry.

Southwire Armorlite® Type MC Cable -Neutral per phase meets or exceeds the following requirements:

^† Ampacities have been adjusted for more than Three Current-Carrying Conductors
^† Ampacities based upon 2023 NEC Table 310.16 and do not take into account the overcurrent protection limitations in NEC 240.4(D) of 15 Amps for 14 AWG CU, 20 Amps for 12 AWG CU, and 30 Amps for 10 AWG CU (independent of the conductor temperature rating and stranding). Also, see NEC sections 310.15 and 110.14(C) for additional requirements.
