What wiring method should be used in the workshop?

The proper choice for wiring in a workshop environment is the use of electrical metallic tubing (EMT) alongside Type NM (non-metallic) cable. Using EMT provides a robust protective conduit for the wiring, which is particularly important in a workshop where tools, materials, and activities can pose risks to exposed wiring. EMT is constructed of metal, offering excellent physical protection against mechanical damage, which is common in a work area.

Incorporating Type NM cable within the EMT allows for flexibility in wiring while still maintaining a level of protection. Type NM cable itself is rated for residential use and is suitable for dry locations, making it ideal for a variety of lighting and outlet circuits typically found in workshops.

This combination ensures that the wiring is safeguarded against abrasions and impacts while allowing for easier installation and access compared to more rigid electrical methods. Overall, combining EMT and Type NM cable meets safety standards while accommodating the unique demands of a workshop setting.
