Near Miss: Almost Fried Myself on a 240V Panel Upgrade Today

Man, just hit my master electrician cert after 15 years grinding in the field, and wouldn't you know it, first big job after is a sketchy 240V panel swap in this old house out in rural Ohio. Customer's been complaining about flickering lights for months, so I pull the meter, start swapping out the ancient Federal Pacific for a new Square D QO, but damn if the main breaker didn't have some hidden arcing behind it. I was two seconds from touching that bus bar when my voltage tester buzzed like crazy, pulled back just in time, heart pounding like a jackhammer. Been doing this in rural Ohio forever, and these old farms always got one surprise waiting. Honestly, think every sparky should carry a Fluke 87V as standard, saved my ass more times than I can count. Still, getting that cert feels good, even if it means diving into more headaches like this. YMMV, but don't skimp on PPE, folks.

Those old Federal Pacifics are a DEATH TRAP, inspectors in my area won't even let you leave one in during a sale, total nightmare for us sparks.

Square D is solid, but I've seen guys swear by Siemens for the price point, especially on residential jobs. Fight me if you disagree.

Always double-check with the Fluke before touching anything.

Master cert? Congrats, but the real test is surviving the idiots who DIY their own wiring. Seen too many close calls like yours from that crap.
