How can I jump my electrical boxes? I just recently bought an apartment building and I would like to make it one whole house and I would like to run the downstairs apartment to upper.. there are to separate boxes that run each apartment side by side.. I was told I could "jump" one box from the other temporarily. How do I do this?

Basically , without seeing the actual arrangement, all I can suggest is remove the two meters, install one larger meter ,install two disconnects matching the panel feeders.

The riser should be large enough, but may need reworking.

Anything done temporary at this location is dangerous and should only be done by professionals, with proper knowledge, tools, and protective gear.
