Is this the exact file you are using as a footprint? If so, instructions for the fix follow, along with some block-building 'best practices'. If not, post back with the actual file you're using as the footprint.
If you are indeed using this file as your footprint, there are a number of things to address: Block files should not contain other blocks; Block files should only contain what is necessary to the block - no junk; The insertion point is pretty far off.
The fix workflow (DO NOT do any of this through symbol builder, just treat it like any other dwg)
1. Open the drawing file and explode the main block.
2. Also explode the block that makes up the graphics.
3. At this point, you should have nothing but attributes, lines, some polylines maybe, and the wipeout. There shouldn't be any geometry in there that is more complex than that, meaning, no more blocks and no groups. If there is, explode/ungroup it.
4. Run the PURGE command. PURGE ALL, then do it again, then again, until it no longer displays purgeable items. Don't worry, you can't hurt the block by doing this. You're just getting rid of junk data. This makes the block file smaller.
5. Finally, the insertion point. Enter BASE at the command line. If it isn't already, define the base point as 0,0,0.
6. Use the MOVE command, and select everything you see. Pick it up by the midpoint of the line that goes all the across the graphics of the terminal block. Set it down on 0,0,0.
7. Save the file.
8. Double check your entry in the footprint lookup database.
9. Restart ACADE.
10. Give it another go.
Did it work this time? It did for me. Post back and let us know.

MAKING BLOCKS - BEST PRACTICES
Some of the things that 'should' (depending on who you speak to) be done to make a proper block:
1. Use only the simplest geometry possible. (I never use anything more complex than polylines and polygons, in ACADE.)
2. Always use PURGE to get rid of unneeded junk.
3. Always use 0,0,0 as your base point.
4. If there is a wipeout, remember that they carry a pretty decent performance penalty. This used to matter more, back when computers had less RAM, but there is still a correlation between performance and the number of vertices in your wipeouts. I always try to 'cheat' wipeouts when I can. Remember, all they *have* to hide is the DIN rail.
