Question: If you saw this drawing note would you always interpret the raceways to be a "Wiremold" type of raceway or EMT etc.?

Without seeing the drawing note, it's impossible to say definitively how it would be interpreted. However, here's a breakdown of the likely interpretations and what additional information would be needed

Why it's not automatically "Wiremold":
"Raceway" is a Generic Term

Raceway is a broad term for any enclosed channel designed for holding wires or cables. It includes Wiremold, EMT, PVC conduit, cable trays, and more.


EMT is also a common raceway
Factors Influencing Interpretation

To accurately interpret the drawing note, you'd need to consider: The Drawing Note Itself

This is the most crucial element. It should specify, clarify or define the type of raceway intended.


Context of the Drawing



Type of Project

A residential remodel might lean towards Wiremold for surface mounting, while a commercial or industrial project could favor EMT or other heavy-duty options.


Location of Raceways

Are they exposed on a wall, concealed in a ceiling, or buried underground? This influences the choice.

Other Symbols and Legends

The drawing should have a legend that defines symbols and materials used. Check if a specific symbol is associated with a particular type of raceway.


Previous Drawings/Specs

If this drawing is part of a larger set, check previous drawings or specifications for consistent use of raceway types.

Industry Standards and Local Codes

Electrical codes (like the NEC in the US) dictate acceptable raceway types for different applications.

Typical Scenarios and Interpretations (Without the Note)



Ambiguous Note (e.g., "Install Raceways")

If the note is vague, you'd need to look at the context of the drawing. If it's unclear, it is best to

ask the engineer, architect, or designer
for clarification. Note with Size/Material (e.g., "Install 3/4" EMT Raceway")

This is much clearer. You'd use 3/4" Electrical Metallic Tubing (EMT).


Note with Specific Brand/Model (e.g., "Install Wiremold V4000 Raceway")

This leaves no doubt. You'd use the specified Wiremold product.

In Summary
You cannot automatically assume "Wiremold" or any other specific type of raceway based solely on the word "raceway" in a note. You need to consider the entire drawing, related documents, and any specific details provided in the note itself. When in doubt, ALWAYS seek clarification from the designer or engineer responsible for the drawing. Flag for review
