AS Bob said
if a device is back fed it must be secured to avoid poping out if the panel cover is removed for service.
408.16 (F) Back-Fed Devices. Plug-in-type overcurrent protection devices or plug-in type-main lug assemblies that are backfed and used to terminate field-installed ungrounded supply conductors shall be secured in place by an additional fastener that requires other than a pull to release the device from the mounting means on the panel.
Don't for get the requirements for gounding second buildings or structures, Article 250.32. Esp if you have interconnecting metal raceways or water piping)
do you need 20 circuits??
