and now my chiropractor is wondering why his boat payment is late. I bought one of those carts last fall after a slab pour in Billings put me on my knees for a week, and let me tell you, it pays for itself the first time you don't have to hear your spine crack like a knuckle. The guys on my crew laughed at me for being soft until they saw me laying down double their footage without a single grunt. Now they fight over who gets to push the thing, which is fine by me because I'm too old to play hero with a bundle of #5 on my shoulder. You want back pain? Go haul rebar like it's 1985. I'll take the funny looks and the $900 any day.

Wait, did you check if the old panel's EOL resistor even matched what the new panel expects? That's the gotcha I've seen bite people more than wrong values, some panels want 2.2k and others want 10k, and if you just swap panels without checking the wiring diagram you're setting yourself up for a headache. I had a similar deal at a restaurant where the old installer had used a 1k resistor because the door contact was actually two contacts in series, so the math only worked out for the old board. Honestly, I've started carrying a small resistor assortment kit in my truck just for this, it's saved me more than a couple of Friday afternoon callbacks. The real trick is to trace the zone back to the actual device before you trust any resistor you find in the field, because half the time it's not even a proper EOL setup anyway.
