Buying Guide: Key Considerations For Exterior Wiring Conduits
- Material and weather resistance: Non-metallic conduits resist corrosion and are lighter, while galvanized steel conduits offer superior mechanical protection in harsher environments.
- Flexibility vs rigidity: Flexible conduits simplify routing around obstacles but may offer less protection in heavy impact areas. Rigid or semi-rigid options provide stronger shielding for high-traffic spaces.
- Size and capacity: Choose conduit inner diameter and wall thickness based on the number and size of conductors, as well as future expansion plans.
- Environmental exposure: Consider sun exposure, moisture, temperature extremes, and potential chemical or oil exposure when selecting a conduit.
- Installation practicality: Quick-connect fittings and accessible connectors save time during outdoor installations, especially for long runs or tight spaces.
- Code compliance: Ensure the chosen conduit type meets local electrical codes and is rated for outdoor use or direct burial where applicable.
- Cost vs durability: Balance upfront cost with long-term durability and maintenance needs, especially in outdoor settings where replacements can be disruptive.
