Eskom have released a fact sheet on selecting and installing household generators. I was initially quite excited because I though maybe they'd highlight some of the problems with camping and site type generators being totally inappropriate for domestic back-up use.....but alas no.
My suspicions were raised when I saw the reference to '12 gauge ground wire' in question 10. After some elementary Googling I see they've mostly plagiarized a Popular Mechanics article that was published in June 2011. At the bottom I see they've cunningly stated it was compiled by Eskom Corporate Affairs February 2015 as opposed to written so I guess they're not even trying to hide the fact it's not their handiwork. I hope they're paying royalties!!!
