I have an additional question regarding when to use a 2-pin or a 3-pin AC cord to the adapter or device.
Specifically, When are 3-pin required and when are 2-pin required? My assumptions were up to now that for Enterprize class products, a 3-wire cord is always required whether it feeds a rack mount unit or a desktop unit. Are there any country exceptions to that? For SOHO units, it is my understanding that either a 2-wire or 3-wire is ok except where the product clasification warrants a 3-wire. Examples of that are PC's, home DSL routers etc. Are there any countries that force the usage of 2-pin cords for SOHO products? How about Finland where they rely on non-grounding for safety at the home? How about a brick powered router that is metal enclosed and being fed by a double insulated adapter? is grounding necessary for the mere fact that it is connected to a telco or cable (if a cable modem)?
