[QUOTE="cotjones, post: 6089934, member: 573988"] peak power is a sketchy concept though also. There is no definite power level at which the coil is guaranteed to fail or not fail thermally. the thermal conductivity of the coil largely comes into play. So the coil will fail at different levels depending on the time a given level of heat has had to conduct through the coil, At which point the properties of the coil itself will change with heat, adding more variables to the problem. heating Copper by 200 degrees Celsius doubles the resistance.
