    What is the applicable definition of "storage?"

    I always heard you guys North were at 50Hz!

    The story was that you could see fluorescent fixtures flicker!

    OK, we all hum at 60Hz together!

    The story has no validity. Canada is 60Hz.

    Canadians have different vision abilities?

    I've seen a lot of fluorescent flicker, some rather strange pattern as well, but have figured it to be poor quality control or other malfunction and not direct result of source frequency.

    Maybe a colder ambient temperature thing?

    Do the electrical grids cross at all? Maybe just places like Point Roberts, WA?

    I don't think it's much of a hazard. The windings might reach 175°C during a "normal" overload, but the lid won't be anywhere near that hot, let alone close to the infamous 233°C. (Fahrenheit 451)

    (B) Clear Spaces. Working space required by this section shall not be used for storage.
    Violation or not, it wouldn’t hurt to label it "CAUTION: Electrical Apparatus - Hot Surface - Keep Clear".

    Don't be so quick to judge. Many people who live in the South don't have much tolerance for the cold, and some people with cold-intolerant medical conditions migrate to the South.

    understand. I know some of those you mention.

    I myself don't tolerate heat very well anymore, summers about kill me, even when it isn't really that hot. I don't like extreme cold, but am fine with 25 - 60 F for the most part while working.
