The Canadian Electrical code is very restrictive with regard to allowing a service to be placed out doors. I have noted the NEC does allow this.
One of the biggest objections is related to breaker performance when it is cold outside.
What about in the state of Alaska? Are there specific amendments to the NEC for Alaska? Are all the branch breakers allowed outside too?
I have seen test data that shows ambient can effect the operation of breakers and that 135% overloads do not clear in the prescribed time in the breaker standards.
Tell me what you know about this.
Thanks
