Yes, always, always, always verify power is off with a multimeter. We just saw a 23 year old electrician electrocuted in Anderson, SC yesterday after he cut a live wire.
I have a bathroom with 2 switches - one for the light, one for the fan. They are on different CB, with the fan being on the GFCI circuit for the outside outlets, and the light on a normal circuit. I got surprised on that one once!!
The correct way and also the way it is taught to electricians in the power plant I worked at and the all of the field workers (Lineman, troubleshooters, underground and etc) is to test your meter first on a known live circuit test what you are going to work on and then test again on the known circuit, also known as live-dead-live testing. This way you are assured that your meter did not fail. The common phrase is “safety rules are written in blood”

I consider all conductors live until proven otherwise.
That lockout plug from Amazon is a nifty thing to have on hand. Thanks.

So true. I should do a video on this…
