I pulled out my electrical panel this winter to replace the battery selector (see cracks in photo). While I am in there I've thought about improving the positive buss to breaker arrangement. As can be seen in the photo, the existing consists of a copper strip screwed to the hole in the stab connector on each breaker. This seems jury rigged. Could it have come from Ericson this way?
I like the idea of the buss directly connected to the breakers (mimimum joints). However, this arrangement depends on the screw cutting it's own threads in the hole on the stab connection. Several of these connections were very loose.
One option I've considered is purchasing a length of copper bus. Found sections 1/8" x 1/2" x72" at Mcmaster Carr. Could drill and tap every 5/8" to screw into but can't seem to identify an E-T-A (or other brand) breaker with the correct configuration.
Alternative would be to purchase a 10 screw Blue Seas bus and run short jumpers to each breaker. Would be neat but add a few new connection points for extra resistance to creep in. Would also want to mount the bis to the back of the panel. Any suggested adhesive? Could attach with screws through the panel with finish washers on the exterior, but would like to minimize visible fasteners on the front of the panel as much as possible.
As usual, the collective wisdom of this forum has probably worked this out before in ways I haven't yet thought of, so am trolling for ideas.
