220V Bipolar PSU : safety rules

Recommended Posts

Dear Midiboxers

I've made a Bipolar PSU 220V AC : +/- 12V DC, following those rules :

=bipolar&s[]=psu]http://www.midibox.org/dokuwiki/doku.php?id=bipolar_12v_psu&s[]=bipolar&s[]=psu

It works fine, i've done it on verobaord with Fuse and switch, but i'd like to protect the user (me !) against electric shocks as it will be handled and used as is (not in a box). I've already put some nails enamel on the 220V circuit before the transformer and i would like to know if it is efficient (and enough !)

Any advices welcome :)
