Aluminium Profile Type Router - Initial questions

[CNCRY]

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

What you MUST NOT do is connect anything to the bolt on the top side that is connected back to the chassis as that would then make a shorted turn. The rubber washers are there to protect the transformer for mechanical damage to the winding.

I'm going to throw a spanner in the works here and point out that I've built dozens of machines that use the bolt thru chassis method with rubber pads and I've never had any issues with shorts, fires or getting zapped with stray volts/current etc.
Like Clives mentions it's a Big No No earthing to the bolt but other than that then you won't have any issues provided the transformer sits on the rubber pads.

So just get on with it and don't worry is what I'm saying. If you want to put a rubber washer on the bolt then why not for what it costs but I wouldn't mess around with Phenolic boards etc.
