What do they mean when they say : "As a rule of thumb: #12 wire may loaded up to 16 amperes, #16 up to 10 amps and # 18 up to 8 amps."
Do I need a voltage meter to make sure I'm not over wiring it? I talked to my dad on the phone tonight and he more or less told me that whether I use the connecting clips or electrical wire that it should be safe. His only concern was whether it would be indoors or outdoors. He might know what they meant by the amps, but he might not. He's a little forgetful and doesn't always remember stuff these days.
Thank you all for the help, between the video and youtube I understand how to wire it together. The parallel webpage was helpful too now I know how to tell them what I want, in the one video they called it "daisy chaining".

"Yeah I'd like this wire daisy chained."
"Daisy-what?"
