The current edition of the NFPA Journal has a good article about electrical maintenance. (Use [url='http://www.nfpa.org/publicJournalDetail.asp?categoryID=&itemID=43863']this link to read the article[/url].)

The article points out that we should not let other priorities distract us from needed electrical maintainance, and it identifies overcurrent devices as being at the top of the list. The article states:

"Although all electrical equipment needs to be maintained, the most important, from a safety standpoint, are the overcurrent devices that trip circuits when a fault occurs. These determine the length of time the overcurrent conditions exist, which determines the amount of heat, energy, and damage that will occur."

But, the article also points out that other areas also need to receive maintenance attention.
