Developers | A cost saving method for your electrical system

Reading Time: 4 minutes

As a developer, you must make difficult decisions in order to keep costs low, especially now with inflation rates, materials shortages, and delays. From the design process to the construction of your project, you must decide which direction to go when it comes to the materials to use in your development. So today, we dive into a topic that electricians are currently facing—What type of electrical conduit to use?

Electrical contractors are dropping PVC for ENT to save costs.

To deal with the current supply chain and shortage issues, developers must find new strategies and best practices—one of those strategies is the installation of ENT instead of PVC in their project.

PVC & ENT—What Do They Stand For?

  • Polyvinyl chloride (PVC) conduit: Plastic conduit is typically constructed from durable PVC and is used to route and protect electrical cables and wiring. It is generally installed within a wall cavity but is also favored in exposed locations such as a basement or attic space to prevent damage to any cabling.
  • Electrical Nonmetallic Tubing or “Smurf Tube” (ENT): is a thin-walled corrugated tubing that is moisture-resistant and flame retardant. A non-metallic, flexible, corrugated raceway of circular cross-section with integral or associated couplings, connectors, and fittings for installing electrical conductors.

ENT is designed to replace EMT, flexible metal conduit, or other raceway or cable systems for installation following Article 331 of the National Electrical Code, other applicable sections of the Code, and local codes.

PVC is getting very expensive and increasing project costs. Some electrical contractors are switching from PVC to ENT to save cost. Here is a breakdown of the price of PVC for the last 2 years, and the recent cost comparison of ENT to PVC:

*Exact ratios of installation labor, weight, and material cost vary depending on the conduit size.
