I'm planning to design a few low voltage DC hobby circuits (<12V) that I want to put in metal project box/enclosures. I intend to power the circuits with regulated AC/DC adapters (Wall Warts). Being that the power supplies will be isolated, can I stick with the floating ground approach I use in plastic enclosures or must I establish a single point chassis ground? Any advice regarding what the rule of thumb is would be greatly appreciated!
