We recently moved and our basement needs work. I would like to put an oven somewhere in the basement. If I'm not mistake it needs a 30A Breaker correct? I looked at the breaker box and noticed that there are some space for a 30A breaker but how will install the breaker in the panel? I know I should turn off the main breaker first but are there any other precautions before I tackle this job? Any pointers or help will be greatly appreciated.
