Electrical Safety

I need someone to answer the attached paper. Very simple terms I need definitions for them. NOTE: each definition should be briefly cited (from where did you get the definition). No Wikipedia, only academic sources. USE NFPA 70E book and you can find all the term there. If you can't access the book use any other academic resources that are available online. Keep it simple and clear. I need this as soon as possible. Two days maximum. I am willing to pay
