/diy/ - Do It Yourself

I have three 230v 20 amp outlets in my garage. It's a standard 3 wire, 2 lines and a ground setup. Now the problem is, there's two breaker panels. 1 old one, and one newer one. The crazy part is one of the line wires for all of the outlets is hooked up to a 30 amp breaker in the old breaker panel, and the other line is hooked to a 50 amp breaker in the new breaker panel. So you have two different breakers (different amps too) providing power to each of the power lines to the outlets.

I'm ok with home wiring, but I'm no electrician. When I saw this though, I started wondering if there's something I'm missing here, or if this is just a batshit fucking crazy setup. Any help?
