Finally got around to hooking up my second meter. I couldn’t put it on the main line because the two wires were too close to each other and there was very little room to maneuver without killing myself so I connected it to my 40amp AC lines. That covers half the amperage in the house. 60amps on my garage and 40 on my AC.
One day I’ll have the box upgraded and I’ll get it on the whole house but for now this’ll have to do.
