yes, the diagram in post 6 is the usual way to mount an open toroidal transformer

if its fitted in a low profile metal enclosure just make sure the lid can not touch the bolt head and form a shorted turn !

Feeling stupid now but, make sure what cant touch the bolt?
The chassis would be in contact with the screw by mounting it in it or am i missing something?

[john swift]

Any connection between the bolt head and the chassis will result in a shorted turn

but if its fitted in a low profile metal enclosure
then it may be possible for the top to be deformed and touch the bolt head if pressure is applied !

How about the lower end? The nut will be in contact there right?

[john swift]

the lower end is OK as the chassis , bolt and top mounting disk don't form a complete turn around the toroidal core

its only when you close the loop by connecting the mounting disk to the chassis by a conductor outside the core

Allright, thanks!
When were at it, what type of fuses would you use for a PSU?
