| 9.4.3 | Running cable through existing raceway
You may already be familiar with raceway, since it is routinely used to hold other types of cable. It is not uncommon for raceway to exist in buildings where LANs are being installed or expanded. Because that is often the case, people often wonder if cable can be routed in existing raceway. The answer depends on the type of cables that are currently contained with the raceway. Can you think of any types of cable that you would not want to run next to CAT 5 UTP cable? This would include any type of power or electrical cable.
