Distance to Main Disconnect

I'm sure this question has been asked before, but here goes anyway.

If you have a service panel which has no main disconnect of its own, and more than 6 breakers, what is the maximum distance from panel to a main disconnect? Also does this main disconnect have to be in line of sight? can it be outside of the house under the meter? any other requirements, etc?

Any help is greatly appreciated.

No limit if the main disconnect is in the same structure. But there are limits as to how far your first overcurrent protection can be from the point of entrance. So it might depend on whether or not your main disconnect also provides overcurrent protection.

OK....the main dis'con looks like a circuit breaker.....so that should be ok(assuming it is in fact a breaker)... right?

Thanks again for the response...

There is no limit on the distance between the main disconnect and the panel. However, the main disconnect must be located at the point of service entrance, or at the closest point inside the building. Putting the main disconnect adjacent to the meter is a common practice and completely legal. After that main disconnect, the panel it feeds could be anywhere in the home and still be legal.

Yes. The main disconnect of your home has to provide overcurrent protection. A breaker will handle that duty nicely, as will a fused disconnect switch.
