What is electrical conduit?

Electrical conduit is a hollow tube that houses and shields wiring from physical damage, moisture, and environmental exposure. Building codes and safety standards require conduit in many applications, particularly where wires might be exposed to impact, moisture, or contact hazards. Different types serve different environments and building types.

EMT (Electrical Metallic Tubing) is a thin-walled steel conduit commonly used indoors in residential and light commercial settings. It is affordable, easy to bend and install, and provides good protection against minor impacts. However, EMT cannot be used outdoors or in wet locations without additional protection.

PVC (polyvinyl chloride) conduit is a rigid plastic pipe used primarily outdoors and in wet or corrosive environments. PVC resists moisture, chemicals, and UV exposure, making it suitable for below-ground installations and exterior work around Sanford. It requires support straps every 3 feet and must be carefully bent using heat or special fittings.

Rigid metal conduit (RMC) is heavy-duty steel pipe that provides maximum protection in demanding applications. It is often required in hazardous locations, wet areas, and for outdoor industrial installations. RMC is more expensive and labor-intensive to install than EMT but offers superior durability.

Electricians determine conduit type based on location, moisture exposure, impact risk, and local code requirements. Choosing the right conduit protects the wiring system and ensures compliance with Florida electrical codes.
