Branch Circuits & WiringQuestion 226 of 521
Which cable relies on its metal armor together with an internal aluminum bonding strip to serve as the equipment grounding path?
a.Type MC
b.Type AC
c.Type NM
d.Type UF
Explanation
Per 320.100, Type AC cable includes an internal bonding strip that, combined with the armor, forms an effective ground-fault return path. Type MC generally includes a separate equipment grounding conductor, while NM and UF use an insulated or bare EGC, not the armor.
