MC Cable Expands Its Reach Electrical contractors have been enjoying the installation benefits of
metal-clad (MC) cable for more than three decades. In jurisdictions
where it’s accepted (and that’s most of them), MC cable saves
significant time over traditional pipe-and-wire approaches, because
conductors and their protective sheathing are installed in a single
step. A number of specialty products now bring the same performance and
installation benefits to a growing number of applications.
Protect Against Ground Faults With Better Bonding The term “grounding” often accompanies “bonding” in manufacturer’s
descriptions of their electrical fittings. It’s a bit confusing, because
grounding and bonding actually are two separate tasks that share the
common goal of protecting building occupants from dangerous fault and
over-current conditions. But, while grounding is the effort to direct
surges of electricity safely to the earth, bonding is the act of
directing fault-related current back to a panel, where it can be
controlled by a breaker or fuse.
AC and MC Cable: Understanding the Difference Armored cable (Type AC) and metal-clad cable (Type MC) can look very
similar, as they both feature flexible metal armor encasing a number of
pre-installed conductors. And both types of product can enable much
faster installation, versus old-school pipe-and-wire methods. However,
AC and MC cable actually are constructed differently from each other,
which leads to differences in their permitted applications.
