Thank you Ray, it shows how much I know about power supply units LOL.
So I will only install a fuse on the incoming AC (black wire). Since this is 110VAC, 15A circuit should I put a 15A fuse? perhaps less?
And how you install a fuse on the 110VAC? with the same fuse holder they sell for the DC circuits? or perhaps a 15A breaker?
Richard thanks for the tip but we have settled the bridge rectifier; Hood suggested earlier a 400PIV, 25A which I will purchase from mpja.com at $2.70 (item #5248 BR)
