White Panel in Hoffman Box

[fifty60]

What is the white panel inside a Hoffman box made out of? This is the plane that the din rails mount on. It must be a conductive material, right?

I have seen metal panels in boxes but I cannot say if they were Hoffman boxes or not

If you are talking about what I think you are talking about it is just a sheet of mild steel that has been painted (most likely powder coat method).

they are painted steel usually.

although you can also get galvanized panels.

I think some very small plastic boxes from other manufacturers come with a plastic mounting panel but they are unusual.

I think some boxes are available with aluminum panels as well. not real common.

If the outer box is steel, then the included inner plate is steel. To check use a magnet.

To determine if it is conductive use an RF sensor such as an inductive prox switch.

What would you expect?

The steel plates are not a very mild steel. They drill and tap hard. Use cutting oil. I believe a dull drill will heat harden the area being drilled. You can break a tap easily. The original TapMagic was real good, the new stuff not so good. Aluminum TapMagic is still good. http://www.tapmagic.com/

You ask many questions, but don't return with feedback on your end solution.

It is conductive, you want it to be conductive or the items mounted to it would not be grounded.
