hi,
se cable is used frequently to feed new or existing sub panels in residential or commercial applications like aprtment complexes. you can not get away with running it unprotected from the meter base to the main, but from the load side of the the main there is no restriction on using it that I am aware of.
Also, I am not aware of any problem feeding a 125 amp panel from a 200A main lug panel. It is all dependant on the load being served.
My main consideration is the size of the main and the ampere rating of the meterbase..I am not familiar with any residential meterbases that are larger than 200A.
I will have to do some research to see what the actual calculation is to determine exactly what the code says about sizing breakers for this type of situation.
I was sure that this is not a unique situation and that someone else has already been down that road. If you are dooing a large home a single 40 ckt panel is not going to be large enough to handle all the circuits, so usually two load centers are installed side by side...i am just curious as to the size of the main etc..
I have seen plenty of 200A panels with 100 & 125A breakers in them!
thanks for any ideas/comments.
I will dig into it and see what the good book says.
thanks
frodo
