15 Amp breaker tripping while printing

have them temporarily cut power at the meter

I think that's true when you're changing the main breaker, because the house feed terminates at the breaker's wire entry and you (well, I) don't want hot feed wires flopping around. To change a branch breaker, though, you just trip the main, the bus bars go cold, and you keep your hands away from the top of the main breaker.

If you're me, though, you first measure the bus bar voltage before you go messing around inside, but that's because I lit up the sky, once upon a time, back when I was young and stupid.

Fortunately, nowadays I'm just stupid... and should probably pull the meter. [sigh]

The building codes are probably different everywhere you go. In the part of Florida where I live, very few homes actually have a main breaker. Don't ask me why. I think it's kind of stupid. Anyway it's actually very easy to change a breaker even with the bus bars hot. (not that I would recommend it for someone who has never done it) There are a few youtube videos on how to do it for anyone who is brave enough to avoid calling an electrician.

Yeah i have changed many a breaker while hot but no main? How is that even possible. All panels are manufactured with the spot for the main. You cant wire it without it. Never heard of such a thing

Years ago you were not required to have a Main breaker, and since a lot of houses don't, you really need to assume especially when giving advice over the Internet that its all "Hot". You also need to assume the person you are giving advice to has zero mechanical or electrical ability.
