I finally understood after sparking up an old junction box
I was thinking back to when I first started, and how we just ran coax everywhere without much thought. The other day, I got called to an old house for a cable upgrade. I assumed it would be easy, like the old days. But when I started drilling, I hit a bundle of phone lines from the 80s that were still live. Sparks flew, and the customer's landline went dead. It made me realize how much has changed with all the old systems still in place. Now I always scan with a detector first, something we never did back then. It's a different world now, with more stuff hidden in the walls.
