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.
Interesting. When I had my panel upgraded they had to put the main breaker right behind the panel. Guess they've got leeway if that's not actually possible.
Probably depends on your locality. Got a new service 4 years ago and the only main breaker is in the service. The city can it it from the meter I suppose if they need to.
