Based on the 2 sizes/thicknesses involved - one is rated at a maximum use (limit) of 130 amps and the other is rated at a maximum use (limit) of 250 amps. I am frequently asked what the temperature limits are for these tapes - and I don't have an answer, nor do I know what conversion method/formula to use... Anyone?? (Fahrenheit or Celsius is okay)
