Fuses, primary, rails, current limiters and channels?

Hey Guys,
Thsi is my first chip amp and torroidal PS (Brian's 4780 kit, but 6 channel). I am using an Avel 800va. I was hoping to fuse each channel, but I am realizing that not so easy, unless you fuse the rails and I am not so sure that is a good idea incase one goes and the other does not. Also, I considering a current limiter in series with the primary fuse -- for 6CH, I was thinking of a 8A current limiter and a 10 amp fuse. What do you guys do for the PS? Thanks for any inputs.
