My house is 100 amp, its no big deal to add a new breaker with power on. They clip in and out, about as dangerous as flicking a light switch.
BUT......the breaker may just be doing its job!!!!
It is important to call someone in to insure that you do not have an electrical issue down the line that is causing the breaker to pop.
This happened everytime I turned on the toaster at home....
Then the toaster tried to electrocute me!!!! The issue was the worn out toaster not the breaker.
