Bob,

     Do you have any opinion on a fuse block with a built-in "forest of 

ground tabs" such as this one?

   Yeah, I looked at those when I started selling the fuse blocks.

   It SEEMS like a good idea. So do switch/breakers.



   It's a matter of architecture.  Do you WANT your single point

   ground to be right next to the bus, or does it fit better elsewhere?

   Also, the products I has available to me then offered fewer grounds

   that bus feeders. In my experience you need about 1.5 times more

   grounds than feeders.



   Same thing with switch/breakers. The notion of combining

   control and protection functions into a single device FORCES

   some portion of the bus structure to be located right behind

   the panel. It can also make for some interesting looking

   bus structures when the switches located for human factors

   reasons don't lend themselves to being grouped with their

   respective busses.



   I think the fuse block, toggle switch and forest of tabs

   ground block as separate products gives the builder a low

   cost, minimum parts count, architecturally elegant solution

   to doing the best we know how to do.
