Main Breaker

I hope someone can answer this simole question. I purchased a home with a newer main panel and it has 2 100 amp main breakers bridged together with a bar on the toggles/switches does this mean I have 200 amp service?

You have an 100A service.

What this means:
- You can have up to 100A @ 240v
- You can have up to 100A on each of your two legs. (in theory 200A @ 120V, but they will never be equally balanced).

And before you ask... if you add up all the breakers in your panel, they will most likely be greater than 100A, which is okay.

For a normal-sized house with at least some gas appliances, 100A is usually quite sufficient.

Ya got 100 amp service there and it is very typical for that size of house if most of applainces are gaz fired then yes 100 amp service will work fine but if all electric appalinces then all bets is off it will have 200 amp service or larger depending on size of house.

Typically most 100 amp service they useally have 20 or 24 space breaker box. [ from time to time 30 space will show up as well ]
