I'm sure this was a question on some test I took in high school, but ...
If I am plugging in 20 feet of heat tape, does it take more, less, or about the same amount of power to wire them as (5) 4' strips or (1) 20' strip.
I'd prefer to have a separate plug-in and strip per shelf since my shelving needs vary and I built adjustable shelves, but I don't want to use insane amounts of electricity either.
If this is an easy one for you, PLEASE share the answer 
Thanks!
Adam
