What is characteristic of BX cable?

BX cable, also known as armored cable, has specific characteristics that contribute to its classification as a type of electrical conduit. One key attribute of BX cable is that it is indeed challenging to pull old wires and insert new ones due to its construction. The metal armor surrounding the conductors can create stiffness, making it difficult to maneuver within existing conduit systems or tight spaces. This can become especially problematic during renovations or repairs when existing wires need to be replaced or new wires added.

Additionally, the cost of BX cable tends to be high compared to other types of wiring options, such as non-metallic sheathed cable (like Romex). The production of BX cable involves extra materials for its armor, which adds to the overall expense.

Therefore, the combination of its challenging handling characteristics and higher cost makes it accurate to characterize BX cable in these terms. Each attribute collectively highlights the practical considerations a contractor must take into account when choosing wiring methods for different applications.
