[QUOTE="dennishoddy, post: 4055950, member: 5412"] Yes. Why would it not be if involved in electrical work? Maybe they thought being in a space vacuum would negate the heat? Everything is flammable at one point or another. We see rocks melt in volcano's. I don't remember my numbers as it's been a "few" years and I've cleared my RAM memory of anything to do with work as I'm retired, but I saw heats with an IR meter that were over 1100 degrees in switch gear. I've also seen the ceramic or whatever it is in 1000 amp fuses burn in half while the fuse element remains intact and working. It's all about Ohms law and heat from that formula if one wants to get into it deeper. Bad contact by corrosion or weak fuse holders creates heat on the surface of the fuse. The current through the fuse is just fine if the end caps are secured tightly, so it just keeps running. Scary situation for the electrician though. I've worked everything from 60,000 Volts to 5 volts DC. You're in a great high paying field that will keep you and your family in a lot of money. Get through the apprenticeship and your world will open up for you. [/QUOTE]
