?I have a 2 inch lb 63 cubic inches diameter. It is on the outside of a house under a disconnect looks like somebody changed the service. It has a piece of SER Cable in it with three 250 kcmils and a ground i need to know how to calculate this its seems to be very small to me. Thanks.:?

Most LB's that size have the wire size stamped on it but if the wire is there you won't be able to see it. I think it is 4 --3/o conductors

Conductor fill may be ok but you might want to check the minimum bending radius if it's installed in the form of a jacketed SER cable.

I agree, in almost every scenario SE cable is an LB conduit body is a violation.
