wiring sub panel to shed

I am running power to my shed (shop). I plan to have 2 110 ACs
, 2 large lights, Fans , 110 air compresser, other misc. tools. My shed is about 30' from the main panel. In the past someone has came out of the main box outside and ran a 2nd 100 amp circut to a 2nd panel box outside. Out of this 2nd box they have ran a 50amp breaker to double oven. A 30 amp to cook top, And 30 to 220 AC. Is this the right way for it to be done and if so how do I proceed with wiring my shed the cheapest yet safe way? What size wire and breaker out of 2nd panel? What size panel in shed with what size breakers in it? What should be ran on each circut out of panel in shed? THANKS 4 your help!!!

It would be preferable to run your feeder to the shed from the main panel rather than from the second panel. A 60-amp feeder of 6/3 UF cable connected to a 60-amp double-pole breaker in your main panel, burying the cable 24" deep out to the subpanel in the shed should be good for your setup. The existing subpanel will provide a good model for your new subpanel, but if the shed is detached, you will also need grounding rods. Don't forget to keep the neutral wires and grounding wires isolated in your subpanel (unlike your main panel). The shed subpanel should probably have all 20-amp circuits on 12/2 cable. You might want to have an electrician compute whether the service you have from your power company can handle the additional load.
