Hi,
I'm designing a simple dual rail PSU using linear regulators. I have a couple of safety/best practice questions.
1. Fuses. I presume the best place to put fuses is between secondary and rectifier rather than after the regulated outputs?
2. Is it safer to mount in an earthed metal enclosure, or unearthed ABS or similar?
3. Is it safer to allow ground to float, or connect to mains earth ?
Thanks,
