Default How to mount a toroidal transformer vertically?

I need to mount two 45v toroids vertically. I know I can use an L-shaped bracket, but what about using U-bolts to affix them to the base of the chassis?

Exclamation Don't!

If the U bolt is conductive and if it is electrically connected to the chassis (which I assumed is metal) it will result in a shorted turn. If you can guarantee insulation of the U bolt from the chassis it will work but will not be a sound design since these locations can be difficult to insulate permanently.

I've always used an L bracket for vertical mounting.

It doesn't matter whether an U bracket is insulated from the chassis or not. In order to avoid a short, the "turn" U bracket - mouting bolt has to be interrupted somewhere.

Best regards!

Andrew, I was wondering about that. I could use some relatively thick rubber to make mats that would go between the toroids and the chassis, and that would also provide some compression/tension for tightening tyraps down.

The insulation is the interruption.
