Sounds ok. Some may be concerned with the buss rating of the meter stack if it is under 800 amps, however there is no requirement to protect it at its rating by an OCPD unless specifically stated in the destructions.Can an over size breaker be used if it is only being used as a disconnecting means? I want to use a tap box with an 800 amp breaker to feed 4 gang stacked meter socket. The 4 gang socket will have 4 150 amp breakers.
I having trouble understanding this scenario.
You’re feeding meters *after* a main disco?
...
What exactly makes the 800 amp breaker oversized? Just the combined ratings of the (4) 150A breakers? Or something else?Can an over size breaker be used if it is only being used as a disconnecting means? I want to use a tap box with an 800 amp breaker to feed 4 gang stacked meter socket.

It’s bigger than the load
As long as it protects the wire and equipment that's fine.It’s bigger than the load
My take on the OP (which may be assuming too much) is that if everything upstream of the 150A breakers were rated for 800A, there would be no question. So my interpretation of the OP is that the question is this:As long as it protects the wire and equipment that's fine.
