as far as google goes, i think i just learned soem stuff, the fat side of the plug is the HOT, and the ground and nuetral are pretty much the same thing...... however, if ther is an internal error with a short of an appliance, the product can ground itself through the nuetral or the ground as a backup failsafe, and you wont get shoced from touching it


now, what if i dont have that ground on our plugs? almost all of of outlets in the house are 2 prongs..... how can i make these all 3 prong, safely? it appears that some plugs are the gfci plugs with the buttons and a couple others throughout the house are also a 3 rong outlet...... how can i verify these are indeed, safe.... and also.... can i make all the otehr 2 prongs into 3 prongs, or would new wiring need to be run or what?
