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.
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.
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.
