What is the professional method to mount Burndy Blocks in a J-Box?

My idea was to buy a PVC block or a Nylon Block and screw the Block to the J Box and screw the Burndy blocks to the Nylon or PVC block.

It dawned on me that there must be a professional method to do this.

Thank you in advance
 
If you mean just mechanical lugs, depending on your application you can buy power blocks. These are mugs that are already mounted to nylon or fiberglass to insulate them from touching each other or metal.

Use an enclosure with a backpanel, Hoffman and Saginaw are two common companies. NEMA 1, 3R, 4, 4x.
The backpanel is separate and mounts on threaded female bosses on the back of the enclosure, Don't short your self on room.

Most terminal blocks like I think you are talking about are already mounted on an insulator - you mount that insulator to the enclosure you are installing it in.

Same ....

You should be able to buy the backplate as an accessory. I mark out the holes for the blocks and tap them to bolt the blocks on. I usually have to drill the mounting holes out just a little to accommodate a 1/4-20 screw.
