Electrical – Where is the Main Shutoff the Cutler-Hammer Breaker Box

electricalelectrical-panel

Kind of confused where my main shutoff is. When I read and looked at breaker boxes for examples, most had a big shutoff right at the top. Where is the switch on mine? I'd like to remove a breaker, but I'd like to turn the whole box off. Any ideas?

What you have is called a split-buss panel.

Code allows up to six "main" breakers or disconnects. The top six double-pole spaces in your panel are all main disconnects. One (spaces 9/11) is the "lighting main" which shuts off the bottom half of the panel.

The lugs at the top of the panel are unfused lines coming from the meter.

As a side note, the single-pole breakers in the top half of your panel are technically a code violation since that caused you to have more than six disconnects to shut down all power.
