I have done some tile work over the years but am far from being an expert. I was on a job site recently and began talking with an electrician about tile installation. He said that ceramic tile had to have “360 degrees of deflection.” I have never heard this term. Does it have relevance or was the electrician just spouting off?

I'm about like you, experience-wise. I can't figure out what it means.
(Do you have more context?)
What he means is that a floor to be tiled must have deflection not greater than L/360, meaning it can deflect 1" for every 360" of length. Here's a good place to check out whether your floor can be tiled:

I think David is right. Another case of someone popping off with slightly distorted info. It would sure be interesting to hear how Sparky would define his own comment.
