What should be done to protect electrical wires running through drywall?

The correct approach to protect electrical wires running through drywall is to install conduit. Conduit serves as a protective housing for electrical wiring, safeguarding it from physical damage, moisture, and environmental conditions that could cause wear over time. By encasing the wires in conduit, you help ensure they remain secure and insulated, reducing the risk of shorts or electrical failures that could arise from exposure.

Using a larger wire size, avoiding running wires through drywall, or using low voltage wires alone does not provide the same level of protection as conduit. While larger wire sizes may handle greater loads, they do not inherently protect the wires from external damage. Avoiding drywall altogether may not be practical, especially in typical construction scenarios where wires need to be routed through walls. Lastly, low voltage wires may be sufficient for specific applications, but they do not address the overall protection concerns associated with regular electrical wiring in residential or commercial settings. Thus, installing conduit is the most effective and safe solution for protecting electrical wires within walls.
