    If you have a older box then you may not have a separate ground bus.

    What ever bus that your box Ground rod is connected to is where the bare ground wire should be connected.

    There does not appear to be a separate ground connection to either bus.

    The main feed wires are definitely larger than #10. They are not labeled, so I can't tell what gauge, but they are at least twice the thickness of everything else in the panel.

    Are you COMPLETELY removing the tandem breakers AND the wiring to them? If so, and it was because they were not being used then they were not a factor in the original panel's load, and you are adding 25-30 amps to the panel.

    They are being completely removed. They feed outlets that are not being used. There are at least 4 dedicated circuits on this panel that feed outlets for window air conditioners. The previous owner must have had air conditioners in every window. I am removing two of these dedicated circuits to make room and have no intention of ever using the others. I was planning on removing the wires from the panel and capping/disconnecting at both ends (panel and outlet), otherwise I'd have to rip open walls all over the apartment to completely remove the wires. That being said, I would still like to test the panel to see how many amps it is drawing before I go ahead with this. What is the best way to test it?

    You need an AMP meter.

    Turn everything on that you can, then use a clamp on meter at the input of the wires to the box. That will tell your total load.


    Be careful playing with electricity.
