Couple of hundred. Make sure to go with a brand name like GE, Square D, Cutler hammer. Stay away from the cheapie brands. My personal suggestion is to go with a min of 200 amp for a home. I have a couple of 200 amp ones I installed for my home. One for the house and another for my shop. I also like to have at least 10 percent spares for future use.
Be sure to get quality circuit breakers, I also suggest a good decent ground. I have a 10 foot long 3/4 inch copper ground rod driven in the ground that I used to replace the pencil sized one that was in here before me. I had a lightning strike not long ago, I lost a lot of electronics had some tripped breakers but I am convinced the ground did its job.
I did my own work dont know what an electrician would charge. I replaced the entire panel for the house, and added a 200 amp panel for my shop and finished it all up in about 3 hours. (Not the wiring in the shop, just the panel and breakers. I had to install new, wiring took up another day as I had numerous 220v runs to make for air compressors, table saw, planer etc. My total cost was under 300 dollars. I bought everything at City Electric over on 1960. Â
