What is the dimension of the generator load conduit entry area if we plan for bottom entry?

• A. 2.50 x 12.0
• B. 3.94 x 19.69
• C. 4.0 x 20.0
• D. 3.0 x 18.0

Answer: (B)

When you plan for bottom entry, the conduit entry area needs a size that can comfortably accommodate the incoming conductors and fittings, while matching the standard opening used for generator installations. The typical bottom-entry opening is 100 mm by 500 mm, which converts to about 3.94 inches by 19.69 inches. This exact size gives enough width for multiple conduits and elbow fittings and still leaves room for grommets and securing hardware. The other options are smaller or not the standard bottom-entry dimension, so they wouldn’t reliably fit the required conduit configurations.
