I need to replace a faulty breaker. Here's a picture of my main breaker box. There's no master switch that I can see that shuts off power to all of the breakers.
Following the line up and out of the box, it runs along the basement ceiling and out through a hole in the foundation.
Let me know if you need to see something else.
Edit. Resolved! I found a master switch on the outside of the house in a panel adjacent to the meter. Weird that anyone can just walk up to my house and turn all of the power off.
This is really strange that there is no master switch. Are you sure this isn't a sub-panel which is wired into another breaker box somewhere else in the building? I'd go hunting, following the main wire.
There's less than half of the number of breakers on here that I'd expect in a house.
There is a subpanel that this one feeds. See the 70 amp breaker? That's goes upstairs to another panel there.
