Yesterday I went out to look a house that is planning on building a stand alone RV garage. He wants to put a 100 amp sub panel inside the garage and told me his 'electrician friend in Alaska' said that he will definitely need a disconnect outside the garage. My initial thoughts are that there is a disconnect in the main panel along with the 100 amp breaker in the main that should serve as a disconnect. Or am I missing something? Is there a code requiring a disconnect on the outside of the building within a certain distance? Kind of like with pools.
The second question is with the ground. I was taught that there is only one ground. And that is at the main panel but seems like I have read somewhere that detached structures require there own ground (ufer). Is that right and where is that in the code book?
Thanks in advance guys.
