Got a nasty shock from a mislabeled breaker in a 1970s house retrofit

I was updating the kitchen wiring in an old Portland home last month. The panel schedule was wrong, and I thought circuit 14 was dead. It was not. My hand brushed a neutral bundle and I got a full 120v jolt. I shut the main off, then used my Fluke T6-600 to verify each wire before touching anything again. Has anyone else found a good way to double-check old panels when the labels are clearly lying?

Yikes, those old panel labels are more like creative writing exercises! I've learned to trust my meter more than any piece of paper taped inside the door. It's the only way to be sure you don't become part of the circuit.

My buddy found a label that said "garage lights" but it actually controlled the sump pump. The meter doesn't lie, but someone had a weird sense of humor.

I read a tip about using colored tape to mark wires as you test them, so you can see at a glance what's live. That extra step seems worth it after a scare like yours. Better to spend a few extra minutes than get another surprise.

Honestly that tape trick sounds good in theory. But tbh I've seen tape fall off or colors fade over time. The meter check is the only real way to know for sure.
