Don't forget to include the difference in having and not having to open the trough in your comparison. :wink:

I have to open the trough anyway as I need to repull the feeders from the disco. to the trough to make new taps. the old wire is actually bare in a few spots. Looks like it got rubbed off or maybe rat-chewed or something. Either way, bare 4/0 wire in a steel trough is not a good idea. Thanks!
