According to the installation description, how far away from the conduit body must the conduits be supported?

The requirement for supporting conduits near conduit bodies is outlined in the National Electrical Code (NEC). The correct answer indicates that conduits must be supported within 18 inches of a conduit body. This is important because proper support helps maintain the integrity of the conduit system, ensuring that it is secure and protected from damage, while also accommodating any changes in direction or adjustments made through the conduit body.

Supporting the conduit at this specified distance prevents any sagging or potential strain on the connections at the conduit body, which can lead to wear and compromise the electrical integrity over time. This regulation is in place to enhance safety and reliability in electrical installations, promoting a sound conduit system that adheres to best practices in electrical work.

The other answer choices represent distances that exceed the code requirements, leading to potentially unsafe conditions if the conduits are allowed to hang unsupported beyond the specified limit. The 18-inch requirement serves as a balance, ensuring both adequate support and flexibility in the conduit layout.
