Which cabling configuration options are acceptable for installation in hoistways?

• A. EMT
• B. IMC
• C. RMC
• D. All of the above

Answer: (D)

In hoistways, wiring must have a rugged, protected path to withstand movement, vibration, and potential contact with moving parts. Metal conduit raceways provide that physical protection and are allowed for vertical installations when installed to code and the equipment manufacturer’s requirements. EMT, IMC, and RMC are all metal conduit options that can be used in hoistways. EMT is a thinner-walled option that’s easier to bend and install; IMC offers greater wall strength with good protection while remaining relatively manageable in weight; RMC provides the strongest, most durable protection for harsh or high-damage environments. Because each type can meet the protection and installation needs when properly installed, all three are acceptable choices for hoistways depending on specific site conditions, space, and code requirements.
