I have several unopened B-Poni's available if anyone wants them. I believe CH/Eaton stopped making them. So if you want to add to your IMPACC/PowerNet system you will be forced to change all of your B's out to I's. At least this was good information when I checked last. been awhile
Contact me if your interested, I was thinking something in the range of 1/4 retail and you pay for the shipping. That should be about half of what you would normally pay.
