I have the service entrance panel in one building(say bldg#1) and it feeds to an existing building(bldg#2) with a 400A underground feeder. An additon is required to the building#2. Due to that total service required is 600A. Can I add a second 200A underground feeder to building#2 while the previous 400A underground feeder is stil there? This is for Ontario Canada. Do not mixup with Rule6-102 whic is applicable for multiple utility services. In my case utility meter is in bldg#1. No more utility meters are required for bldg#2.
