Conduit Selection Guide for Cable Protection

Step 1: Identify Application Type

Flexible conduit for machinery with moving parts. Rigid conduit for fixed installations. Split conduit for retrofit without disconnecting cables. Liquid-tight for wet environments.

Step 2: Determine Protection Level

Light duty: indoor, low mechanical risk. Medium duty: general industrial. Heavy duty: construction, mining, heavy machinery. Extreme duty: military, aerospace.

Step 3: Choose Material

PA (nylon): flexible, good chemical resistance. PVC: economical, UV resistant. Galvanized steel: maximum mechanical protection. Stainless steel: corrosion resistant. PVC-coated steel: waterproof + strong.

Step 4: Check Environmental Conditions

Outdoor: UV resistance needed. Underground: corrosion + crush resistance. High temp: metallic or PTFE conduit. Chemical exposure: check compatibility chart. Fire safety: metallic or LSZH conduit.

Step 5: Verify Standards

IEC 61386: international conduit standard. UL 1696 (NFPA 70): North American. EN 61386: European. BS 4568: British standard. Ensure conduit meets local electrical code requirements.

Quick Tips

Allow 40% maximum fill per NEC/NFPA 70 for power cables. Always use proper fittings — never mix conduit and fitting brands without verifying compatibility. For outdoor installations, include drain holes at lowest points.
