What is flex conduit? Flexible Conduit Systems are designed to provide the very same cable protection solutions as Rigid Conduit Systems- protecting cables, conductors and wiring within industrial, commercial and even residential applications.
What is flexible conduit used for? Flexible conduits are used to connect to motors or other devices where isolation from vibration is useful, or where an excessive number of fittings would be needed to use rigid connections. Electrical codes may restrict the length of a run of some types of flexible conduit.
Is flexible conduit code? You may use flexible metal conduit in any length as long as you follow the Code rules for support (Sec.
350-18) and grounding (Sec.
250-18).
Where do I need flexible conduit? Flexible metallic conduits or FMCs are often used in commercial buildings. This conduit is specifically used in areas where it is not possible to use a rigid conduit. It can provide ample strength and protection with the added benefit of flexibility.

Should I use metal or plastic conduit?
PVC is an excellent corrosion resistant material and doesn’t break down in corrosive environments like salt water or chemical exposure.
The downside to PVC is that it does not have grounding capabilities, being a non-metal conduit.
To address this, electricians use an extra grounding conductor in all PVC conduits.
How long does it take to install conduit?
You can get rigid couplings and connectors that use set screws and doesn’t need threading. I would use 6 man hrs per 100′ if 1/2″, 7.5 hrs if 3/4″. Use a man lift if mounting more than 12′ above floor. Additional labour for boxes and devices.
