Hi Marc

I'm not sure, but the ones with the massive bus leads look like indoor
current transformers for a 2,400 volt distribution system. They are put in
series on a line wire to measure current flow. The ones with the beautiful
square cores are perfect for homebrew HV transformers. Big square cores are
difficult to find, and I have never found one myself. If they are as big as
they look, they are a FANTASTIC find. They got my attention!
