According to the Belden wire table, 10awg carrying 32 amps will produce a 35C rise above ambient. And according to them, the bundling factor is 1.0 for 1, 2, or 3 bundled wires. If you're qualifying anything up around 40C high temp, your wire's going to be 75C.
5C doesn't give you much overhead for 80C rated wire. So, you might want to think long and hard about using 80C rated wire for such an application. IMO, you'd have to start with a minimum 105C rated wire. 8awg at 32 amps looks more like 23C rise above ambient. - Doug McKean ------------------------------------------- This message is from the IEEE EMC Society Product Safety Technical Committee emc-pstc discussion list.
