I believe that someone done this to be intentionally, and it did infact catch on fire. The two wire were spliced together and it lay across my heating vent. Mind you the wire laying across the heater never melted it was just off the heater were it caught afire. I was thinking that something was pasted or pored on the wire to make sure that it would catch, something like asatone or a paint product? Here are some of the numbers and letters that were on the wire AWM 2468 VW-1 60 degree 300V AWG24 H.W.G. C. Please and Thankyou Im just looking for answers.
Hi, A live conductor has more possibility to fire.Firstly u put the path of wire in a wrong way.A live conducor in the field of heat may produce some arcs and if proper quenching methods are not adopted,it may cause fire. As per the specification of wire u given,it is sufficient.But because of the atmospheric conditions and temperature from the heater,the electrical insulation failed . Anyway, pls don't adopt such type of wiring. Thank u
It's possible for the wires to catch fire if there was a bad connection. When you have a connection it gets warm naturallyIf the wires aren't connected correctly the wires can get hotter because of the way the electricity is traveling and catch on fire.
The heat duct only gets to about 110°F, well below the ignition point the wire. If it's not too hot for a human to touch it's not too hot for the wire. Heating ducts are often electrically connected to Earth ground. A break in the insulation, a bad splice, or exposed splice could cause a short. A partial short can cause arcing. AWG24 is small. It is only good for several Watts. Sending excessive power through the wire causes it to heat up, and the insulation fails, and if it continues the metal itself can burn. Melted insulation from small wire like that can catch fire from spark or enough heat. The ignition point is not very high. I can easily cause AWG24 to catch fire. Placing household chemicals on the wire would not likely cause a fire. Acetone, alcohol, and such dry quickly, there'd be nothing left to cause a fire.
