Which practice is recommended when pulling a group of cables through conduit?

When pulling a group of cables through conduit, making a snout is a recommended practice. A snout is a tapered end, often made by using electrical tape to wrap the cables into a conical shape. This design allows the bundle of cables to be presented more smoothly to the conduit, reducing resistance and friction as they are pulled through. A well-made snout can help prevent snagging and can ensure that the cable ends are less likely to get damaged during the process.

Using a drill might seem like a tool for assisting with the installation, but it isn’t typically recommended for facilitating cable pulls through conduit. Cutting the cables to length could lead to unnecessary waste and complications if the lengths are measured incorrectly, which can be avoided by pulling the cables in longer lengths initially. Twisting the cables together could create difficulty in managing the individual cables and can hinder their ability to move smoothly through the conduit, potentially leading to damage or increased friction during installation. Hence, making a snout is preferred as it ensures a more efficient and safer pulling process.
