NOTE

CONDUIT WIRING AND FITTINGS II

Conduit wiring refers to a method of electrical wiring installation where electrical conductors (wires or cables) are enclosed within conduits, which are rigid or flexible tubes made of metal or plastic. Conduit wiring provides mechanical protection to the conductors and enhances electrical safety by preventing accidental contact, damage, and exposure to environmental hazards.

Types of Conduit Wiring Fittings

  1. Conduit Couplings: Couplings are used to join two sections of conduit together, allowing for continuous runs of conduit. They come in various sizes and materials to accommodate different conduit types and installation requirements.
  2. Conduit Connectors: Connectors, also known as fittings or fittings boxes, are used to connect conduits to junction boxes, outlets, switches, or other electrical devices. They provide a secure and watertight connection between the conduit and the device, ensuring electrical safety and code compliance.
  3. Conduit Elbows: Elbows, also called bends or sweeps, are used to change the direction of conduit runs, allowing for turns, corners, or changes in elevation. They come in different angles (e.g., 90 degrees, 45 degrees) and radii to accommodate various installation needs.
  4. Conduit Tees: Tees are used to create branch connections in conduit runs, allowing for the installation of additional circuits or devices. They provide a junction point where one conduit splits into two or more conduits, maintaining continuity and organization in the wiring system.
  5. Conduit Adapters: Adapters are used to transition between different conduit sizes or types, allowing for compatibility between conduits, fittings, and devices. They facilitate smooth transitions and connections in conduit installations where different components are used.
  6. Conduit Bushings: Bushings, also known as grommets or insulating bushings, are used to protect cables or wires from abrasion and damage where they enter or exit conduits or junction boxes. They provide a smooth and insulated pathway for cables, reducing the risk of insulation wear and electrical hazards.
  7. Conduit Locknuts and Washers: Locknuts and washers are used to secure conduit fittings to junction boxes, devices, or other fittings. They ensure a tight and secure connection, preventing loosening or detachment of fittings during installation or operation.

EVALUATION: 1. Define conduit wiring
