Another point to remember when a wall wart is used - make sure your ground
connection is established BEFORE you power the equipment up. Otherwise it is
possible for the wall wart powered equipment to jack itself up to a higher
voltage relative to earth, then nasty things happen when you make the
connection. This is a problem with ALL double insulated/unearthed equipment.
