Constrained layer damping tape on toroidal transformer?

I just bought a toroidal transformer for a project and it actually came with a foam mounting pad for isolation. I plan on gently tightening the mounting bolt so the foam doesn’t compress too much. Not bolting it down at all seems a little too risky.

Thanks for the tip, Ralph! I think I’ll mount my transformer with a non-magnetic stainless bolt.

I would like to know why you say not to use a stainless nut, though. I build a lot of stainless parts for race cars and for food and beverage and try not to use stainless nuts on stainless bolts due to galling, but that’s only if they have a decent amount of torque applied to them. For lightly tightened things like a transformer, though, there usually isn’t a galling problem. So, why not use a stainless nut? You could always use a little bit of anti-seize if you’re worried about galling.

Sorry, but not bolting a high voltage component to the chassis is idiotic. Plus, if you isolate the bolt and transformer correctly, it will be like it’s not bolted in at all until you actually need to count on the bolt, like if you pick the component up and forgot you didn’t bolt it in, someone bumps it, etc.

Why not leave the transformer outside of the chassis and just run the wires into it? I mean, you might as well go all the way if you’re going to be dangerous about it.
