If your state plans on adopting the 2003 IMC, you may want to consider proposing a change at the state level to section 506.5.3.

The section states that: "an upblast fan shall be hinged and supplied with a flexible weatheerproof electrical cable to permit inspection and cleaning.

Am I the only one that thinks it should read something like "...and supplied with an approved flexible wiring method, in accordance with the National Electrical Code" ?

I would hate to think that the IMC governs wiring methods! I couldn't get this change in on time to the national level, but I will be submitting it at the state level...you may wish to do the same before you have to break out the Mineral Insulated Cable!
