Here's what I want to do, but I need some advice on how to do it:

We will have a 200 amp service panel at the new house. I want to run a 100 amp service to the barn where I will have a second panel box. All wiring will be direct burial cable and I may install it in pvc just for added protection.

I was all set to install a 100 amp breaker in the 200 amp house service panel box and connect the run from the barn to the 100 amp breaker. Then I read the post in "Electrical Panel" that mentioned the added heat from the single 60 amp breaker vs the 20 and 40 amp breakers. This really got me to thinking that I may be in for trouble if I use the 100 amp breaker to feed the barn electrical service

What do you suggest? I don't want 2 meters or anything like that, but I want to ensure that I can run electricity out to the barn safely. Thanks for your help.
