Southwire Romex® Brand SIMpull® Type NM-B (nonmetallic-sheathed) cable may be used for both exposed and concealed work in dry locations as specified in the National Electrical Code®. Le câble NM-B est principalement utilisé dans le câblage résidentiel comme circuits de dérivation pour les prises, interrupteurs et autres charges. Le câble NM-B peut être utilisé dans les vides d’air des blocs de maçonnerie ou les murs carrelés si les murs ne se trouvent pas dans des endroits humides. La tension nominale du câble NM-B est de 600 Volts.

* 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 if size is present in table). Also, see NEC sections 310.15 and 110.14(C) for additional requirements.
* Inductive impedance is based on non-ferrous conduit with one diameter spacing center-to-center.
