Yes I did look at the link, thank you. It's a 30 amp service box and the one in the illustration does look like it. I'm just trying to do some research prior to this week end. My jobs getting in the way of actually going and getting my rig from storage to work on it. I am a little intimidated with the electrical part. I was hoping it would show a way to access the breaker Box in the illustration you sent me however when I looked at it looks like theres four screws on the front thats once removed more likely to give me access to the breakers. I just need to figure out how to remove the breaker and from the Box and install the new ones. I understand there's a latch or a retainer that keeps the breaker in the slot that needs to be Removed?
