Buying Guide
- Intended environment: Choose outdoor or direct burial rated conduit for exterior installations, or indoor-rated solutions for panels and equipment cabinets.
- Diameter and wire count: Confirm that 2″ conduit accommodates the total cable diameter and number of conductors in your run; use innerduct or a higher gauge if needed.
- Material and flexibility: PVC and non-metallic conduits are lightweight and corrosion-resistant, while flexible designs help in tight spaces and complex routing.
- Fittings and compatibility: Ensure the conduit kit includes compatible connectors and that they work with your system’s existing connectors (straight and 90-degree options are common).
- Installation considerations: Look for smooth interiors to ease pulling, minimum sharp edges, and ease of cutting or joining in the field.
- Code and compliance: Verify that the conduit and fittings meet local electrical codes and utility requirements for your project type.
