Fusing for Bias Supply? Fusing for the OT?

[makinrose]

I have a couple of questions on fusing. 

A.  I recently started using some transformers with a separate bias winding that I plan to use with a full wave bridge rectifier.  Is it good idea to protect it with a fuse?  I'm assuming if I did fuse it I'd use a slow blow 2 to 3 times the current rating of the winding?

B. While I fuse the windings on the power transformer is advisable to use fuses for the OT too? Or would that be redundant?   If I should so what's the most effective way to do that?  

Thanks everyone for the help!
