Romex, which is a brand of non-metallic sheathed electrical cable, should not be placed in conduit for various reasons. One reason is the heat generated when Romex is pulled through the tight space of the conduit. To avoid any safety issues, it is best to stick with insulated wires when using a conduit. Here are some other reasons why Romex is not recommended for use in conduit:
Romex is not designed for conduit use: Romex is not manufactured to be installed inside a conduit and it lacks the required insulation, which can cause overheating and melting of wires inside the tube.
Flexibility: Due to its stiffness, Romex wires don’t always fit smoothly inside conduits which can cause friction and result in heat that may lead to electric fires.
Lack of ventilation: Conduits that are supposed to improve space utilization in the electrical conduits by compacting the wires also prevent air circulation, not allowing the heat dissipation resulting in excessive heat that can damage the wire insulation over time.
In summary, while using Romex in conduit may seem like a cost-effective option, it’s not worth the safety risks. It’s always wise to ensure safety first and invest in efficient, safe electrical wiring solutions.
