What must be done to all cut ends of rigid conduit?

The requirement for cut ends of rigid conduit is that all cut ends shall be reamed. This process involves smoothing the rough edges and removing burrs from the cut surface of the conduit. Reaming ensures that there are no sharp edges that could potentially damage conductors when they are pulled through the conduit. Furthermore, reaming helps to facilitate easier insertion of electrical conductors and minimizes the risk of short circuits or grounding issues.

Additionally, preparing the cut ends through reaming helps to maintain the integrity of the conduit system by promoting a proper fit with connectors and other fittings. This procedure is vital for ensuring both safety and compliance with electrical codes that mandate neat and effective installations.
