For those of us who, for one reason or another, have to plan on bugging in, this might serve as a reminder to stock some cheap but necessary items that you may not have considered. Judging by the number of survival threads and articles that I have read, a number of us plan on maintaining, if possible, some sort of energy source should EMP, flood, hurricane, terrorist act or other event disrupt our electric service. At times like this, we can expect blackouts, rolling blackouts, brownouts, surges, peaks or other electrical gremlins to occur. All of these things place stress on electrical and electronic devices and the components designed to protect them; fuses. In addition to blowing out, fuses wear out. This is most common in devices that draw large amounts of power and are switched on and off frequently such as home HVAC units. Heavy current flow through a fuse generates heat and the fuse link expands and contracts with the temperature change until metal fatigue finally takes its toll.
