Spade Connector at Main Lug

[CNewhouse]

Would this be considered a double tap? I don't think I've ever seen this done.

Wondering if the connector would prevent the lug from securing the 4/0 aluminum conductors properly.

I doubt the breaker's connector was engineered for that. Also, paralleled conductors need to be same material, size and length, so that the current divides evenly between them. Write that baby up.

Then there's that copper on aluminium thing.

I was wondering about the copper and aluminum. Thanks fellas.

All the connections in that meter main are incorrectly made. I doubt it was done by an electrician.
