14/3 NMD 90 Cable

14/3 NMD90 electrical wire has two main types: two-core cable and three-core cable, both with exposed ground conductors. NMD90 cables use annealed (soft) copper conductors and are insulated and protected with heat-resistant thermoplastic polyvinyl chloride (PVC). Protecting the conductors from moisture, chemicals, and physical damage is essential to ensure long-lasting performance and safety. Additionally, each individual conductor is wrapped in a nylon jacket, providing an extra layer of protection. The overall construction includes a durable PVC jacket that encapsulates all conductors, increasing their resistance to external elements and potential wear and tear during installation and use, providing safe, efficient electrical wiring for a variety of applications.

Application

14/3 NMD90 electrical wire offers a variety of applications, making it suitable for both exposed work in dry conditions and concealed work in dry or wet environments. These cables provide flexibility in a variety of installation scenarios. Temperature considerations play a vital role when installing NMD90 cables. Before installation, the cable material must be stored correctly to ensure that it remains above 0°C for at least 24 hours. The maximum allowable conductor temperature for NMD90 cables is 90°C. Able to efficiently handle current while maintaining safety standards, this pre-installation preparation guarantees optimal performance and longevity of the cable in a variety of environmental conditions. The maximum voltage rating is 300 volts.

Certification

NMD90 cable is UL and cUL certified to meet the stringent safety, thermal, and performance standards established by Canada. The cables meet CSA C22.2 No. 48 standards, making them a reliable choice for wiring in residential and commercial buildings in North America.

FAQ

Q: What does NMD90 mean on wire?

A:"NMD90" is a designation for a specific type of electrical wire commonly used in residential and commercial wiring in Canada. N stands for Non-Metallic. M stands for Moisture-Resistant, and D stands for Dry. The "90" refers to the maximum operating temperature rating of the wire, which is 90°C (194°F).

Q: What is the voltage of NMD90?

A: 300 VOLTS

Q: Can you put NMD wire in conduit?

A: Yes, you can put NMD (Non-Metallic Dry) wire in conduit. Conduit is typically used to protect wires from physical damage or in environments where additional protection is needed, such as in outdoor, wet, or exposed locations. Conduits also make it easier to replace or add wires in the future. While you can run NMD wire inside the conduit, it's not usually done because NMD wire already has a protective sheath, and the extra sheath adds bulk, making it more challenging to pull through the conduit. In tight spaces or long runs, pulling NMD wire through the conduit can be difficult due to its stiffness and the friction created by the non-metallic sheath.
