After this thread was posted, I split the circuits on the fans so the main puller is fed by an auto-reset circuit breaker and the pushers are protected with a separate in-line blade fuse. The two circuits now do not share the same fused feed. I never liked the "single point of failure" with the one glass fuse feeding all the fans. That was such a trivial mod that it didn't even warrant a new thread with detailed pics.
