Study Notes
Purpose of Electrical Conduit
- Protects electrical wiring from physical damage, moisture, and chemical exposure.
- Provides a structured pathway for electrical conductors, ensuring safety and organization.
- Facilitates easier upgrades or repairs to wiring without considerable disruption.
Materials Used for Electrical Conduit
- Rigid Metal Conduit (RMC) made from galvanized steel or aluminum, offering durability and strength.
- Intermediate Metal Conduit (IMC) is lighter than RMC but provides similar protection.
- PVC Conduit is non-metallic, lightweight, and resistant to corrosion, suitable for wet environments.
- Flexible Metal Conduit (FMC) allows for bending and maneuvering in installations, adapting to complex layouts.
Installation of Electrical Conduit
- Typically installed by licensed electricians or electrical contractors at the site of electrical equipment.
- Electricians assess project requirements to determine the best type and layout of conduit needed.
Wiring Regulations
- National Electrical Code (NEC) often governs the use, form, and installation specifics of conduits.
- Local building codes may impose additional requirements and standards for electrical installations.
- Compliance with these regulations ensures safety, reliability, and proper function of electrical systems.
Early Interior Wiring Protection
- Knob-and-tube wiring was commonly used for interior wiring protection in early electric lighting installations.
- This technique involved porcelain knobs and tubes to support and insulate wires, though it is now largely outdated due to safety concerns.
