I have a question on article 338.10 b (4). It says where installed in thermal insulation you have to use the 60 degree column. Can anyone explain what thermal insulation is. By reading this, it says now number 2 alumium ser is only good for 75 amps. Might be wrong how iam reading it but wanted some opinions.
