After struggling getting my 3 wires into their terminal blocks, using my multimeter to ensure I had enough connection without too much extra resistance (highly recommend doing this step, if even just to ensure you have a good connection), I managed to get the cover back on and ran my wire down the support beam under my house. I had to trace some knob and tube and cut it out as part of this, since two lines were in my way… No big deal, it took me about 40 minutes to climb over, behind, and move enough stuff that I got my 30 foot spool to unwind and terminate in my breaker.
