Ok, so I've been planning and shopping the past two weeks, and I plan to start decorating after Halloween. I am using mainly 16-gauge extension cords, especially for the crepe myrtle. I purchased a grounded 3-way for it, so I think I will end up stacking 3-4 plugs (no more) and hook 1-2 strings into some of the end plugs, which should be less strain (stacked plugs, no melting Lol). The CM will be hooked into an outlet in the basement which SHOULDN'T be on the same breaker as the other receptacle. I will then be hooking the same amount of lights into the other plug as usual (I threw out my DIY mini trees and purchased spirals because I like them better) plus maybe 2 more strings than usual (about 270 more incans added to that outlet). Then, I will hook the dogwood and cross into another outlet. I also plan to look at the spreadsheet posted further back on this thread. I would appreciate any kind of constructive criticism/advice on my plan, especially with electrical safety (I'm a horticulturist, I just like Christmas decorations, no electrical experience).
