Any time low-voltage cables are part of an electrical installation, they need to be in conduit.
Low-voltage wiring is susceptible to damage or disruption from other sources of power such as regular household electricity. To protect your wiring and ensure that it runs safely and efficiently, conduit should be used.
Conduit creates an enclosed space for the low-voltage wires so they can’t be easily damaged or interfered with by other electrical systems. It also guards against water and moisture which can cause electrical shorts or destroy insulation. Placing low-voltage wiring in conduit helps to provide maximum protection and longevity for the life of your wiring system.
In some cases, low-voltage wiring does not need to be in conduit. For instance, in an area of a building where there are no other electrical systems or possible interference from water or moisture, then the wiring can often be run without the need for additional protection. However, these instances are rare and should not be assumed, so always double check with your local code enforcement office for approval before proceeding.
Using conduit will help keep your wiring system safe and running efficiently for years to come. With proper installation and maintenance, you can rest assured that your wiring system is well-protected and securely in place.
