[RE-wrenches] lay in lugs

[Dan Rice]

For the record, another equivalent of the Ilsco and Burndy lugs already
identified is the NSi GLC-4 DBP.

| Burndy's changed its part# from the CL50-DB-T to the CL50-1TN. Still
| direct-burial, still tin-plated, still "commonly used for solar panel
| grounding." The tech support guy I spoke with last December said that
| their lugs are now all direct-burial, so they decided that there wasn't
| a point in keeping up the DB designation.
