Klillemo,

I agree with MasterInBama, also.
It looks like the neutral goes under the clamp and into the weatherhead.
If your brother in law's house is around here (I'm also in the Metro), then this is actually a not uncommon solution for bonding the parts of the service entrance to the line side grounded conductor, when the socket to mast connection is not trusted or approved.

I see it from time to time on plain old 120 / 240 Volt three wire single phase services.

The grounded conductor, connected to the overhead drop does continue into the meter socket. Cut Xcel's seal, you'll find it there. . . . I'll just bet.

Mast is only neutral conductor

Mast is only neutral conductor

Nope, the mast only has two conductors. The neutral feed terminates at the clamp below the weatherhead and goes no further.

I like intentional connections. This connection relies on too much happenstance for my comfort. I am sure that there will eventually be, if not already, some swing in neutral voltage depending on the household load. Enough swing in the neutral and appliances will start to fail from overvoltage.

Thanks one and all for your contributions.
