Which types of liquidtight fittings can be used specifically with LFNC-B?

The correct answer highlights that only fittings marked "LFNC-B" or "FNMC-B" are suitable for use with LFNC-B (Liquidtight Flexible Nonmetallic Conduit, Type B). This specification is important because it ensures compatibility and maintains the necessary standards for safety and performance in electrical installations.

Fittings marked "LFNC-B" indicate that they are designed specifically to accommodate the characteristics of this type of conduit, such as flexibility and resistive properties against fluids and corrosion. Likewise, "FNMC-B" fittings are applicable in similar contexts and are rated appropriately for use with conduits of this nature. The use of compatible fittings helps prevent issues like leaks and failures that could arise from using fittings not specifically designed for LFNC-B conduits.

This understanding is critical for electricians and installers to adhere to code requirements, ensuring not just compliance but also the safety and reliability of electrical systems.
