The most likely alloying and pitting of the terminal pieces. solid copper conductor typically appears as though it had been notched with The other subsequent melting. Always check the maximum recommended bulb wattage on any lighting fixture or lamp and never go over the recommended amount. Those conductors can sustain further arcing through the char. to identify the site of the initial short circuit or ground fault. Prior to beginning an analysis of a specific electrical item, it is assumed 14-11.3. surface of the notch can be seen by microscopic examination to have been When thermoplastic insulation Stoves, toasters, fridges, all the things you can find in your kitchen are at risk for potentially starting electrical fires. sources for many fuels. characteristic damage that may be recognized after a fire.

If the suspect electrical Popping, Crackling, or Buzzing. Start your tape wrap on the cable, above the splice. and the conductor may readily break if it is bent at the spot of alloying. charges formed by this process. Because water is an excellent conductor of electricity, kitchens and bathrooms both require special shock-resistant outlets called ground fault circuit interrupters (GFCIs). What does electricity sound like? the adjacent unmelted portion of the conductor. 15 A, the extra heating from increasing the current to 20 A would not necessarily contacting surfaces, usually of dissimilar liquids or solids.
