The reason that I ask is that I came accross this some time ago & it has made me cautious.
"When I used toroidals for power sources I was made aware that these devices
exhibited substantial switch-on surges on power up. Not fancying subjecting my
very expensive DCC kit to possible hazards I arranged to feed the toroidal
outputs to commercial style 12 V latching relays to isolate any nasties from the
loads."
I don't remember where I got it from but I could probably find it again if I need to. It might be complete rubbish but confirming that, one way or the other, is way beyond me.

Sounds like it's been through a game of chinese whispers. The primary side (the mains input) may exhibit a switch on current surge which can cause fast blow fuses to pop. You should use anti-surge fuses with toroids.
