So I was about to mount my 750VA Toroidal transformer to the cabinet back board with the supplied fixing bolt, metal plate and large rubber washers
e.g this kit > https://airlinktransformers.com/imag...photo1_CM5.JPG
Plan was to drill and tap the metal back plate and secure the bolt into it.
Then I read this - https://diy.stackexchange.com/questi...-metal-chassis
From what I understand the bolt itself plus the top mount plate and chassis can form a C shape around the winding and induct a current. People mention fires and things blowing up which I'd like to avoid!
So now I'm thinking to mount to a phenolic (insulating) sheet so the mounting bolt does not touch the cabinet back plate directly. The transformer also has an earth wire.
Any issues with this, or better suggestion people use?

Thanks
