Before I started the electrical it was mentioned to tap directly off the 200A meter feed straight to the 100A shop panel. This would make the shop panel a "main panel". The disadvantage is that I would need to kill the 200A main (which also feeds the house main panel) to work on the shop main panel. I decided to add a 100A disconnect below the 200A meter main, and feed the shop panel from there. The only purpose of the disconnect is to allow the power to be cut to the shop panel without killing the house power. This still makes the shop panel a "main panel". The shop panel is still fed directly from the meter main at the pole. As I understand, A sub-panel is fed from a main panel with separate breakers. This would be true if I taped the house 200A main breaker box and fed the shop 100A box from there, which is not the case. The Shop main panel is wired the same as the House main panel, and nether feed each other.
I am familiar with electrical safety, as my concern for not seeing a solid ground with the ground check. I feel confident that with two ground rods down (one more than my old shop has) I should be fine. The old shop has stood for 6 years, and I run computers / internet / OTA TV / and a bunch of other electrics and haven't lost anything to lightning (yet). I will keep these concerns in mind with the new shop as I move forward. I may be getting a full building MOV suppressor from a decommissioned one at work that would mount outside the main panel that would protect all the circuits from spikes.
Thanks for everyone's concerns and advise, what I have is a far cry from the extension cord method, and the old shop tied to the house main through a 20A breaker.
