I have an MOV with FLA=15.1A and an installed cable with a rating of 14A. I have been asked to deterine if this will be acceptable. I ave used ETAP to show that the damage curve will not be approached based on the stroke time of the valve, but I am being asked what the temperature of the cable will be after the stroke is complete. In other words, I'm looking for a way to calculate the temperature of a cable after short duration overload.
Just because I know everyone will ask:
The cable is 600V, 3-conductor #10 with CPJJ insulation. I know it's rated at greater than the 14A but this is a design standard I am required to use.
Does anyone know of a calculation method for this that I could reference in an exception to my comany's design standard? It would need to be ANSI or IEEE or something (probably ICEA).
