What is a general recommendation for the size of conduit for a mast?

The general recommendation for the size of conduit for a mast is indeed that it should be 2 inches or larger. This is due to several important reasons related to safety and functionality. A mast typically carries conductors that may be involved in supplying power, and larger conduit sizes help accommodate the necessary wires while also providing space for proper bending and pulling of the wires during installation.

Furthermore, using a conduit size of 2 inches or more allows for better protection against physical damage and environmental factors. It provides more room for air circulation, which can help to keep the conductors cooler, ultimately contributing to their longevity and reliability. A larger conduit can also facilitate easier upgrades or replacements of wires in the future, since pulling multiple or larger gauge wires through the conduit can be quite challenging in narrower sizes.

Using a conduit size smaller than 2 inches could lead to overcrowding, making installation more difficult and increasing the risk of conductor damage or failure. Therefore, opting for a conduit size of 2 inches or larger is a standard practice in ensuring both compliance with electrical codes and the safe operation of electrical systems.
