I would feel comfortable if the size of the GEC was based upon the size of the MBJ since the service size doesn't take us beyond the Table 250.66 sizes.
If the MBJ is factory installed, and it looks like it is, the only item would be to determine its size so that a properly sized GEC could be installed.
The images are posted on my site also and I asked Ryan to send them in so that we could see what the service looked like.
