The job ended up taking a bit longer than anticipated, but after much sweat, some cursing, and only a minor injury, I ran the new power circuits as planned.
My laser is still several weeks away from being delivered (I hadn't anticipated it taking this long to arrive), but I'm taking this time to try to prepare the space where my laser will live. Part of this includes running a couple new electrical circuits to handle the load of the laser and it's support machines.
