Step one: For just 4 circuits, you'd be better off just home running all 4
back to the main panel. Lots less hassle and discussion. If you're out of
room on the main panel, then put the sub panel right next to the main and
see step one.

Hello, I want to install new circuits in my basement and I want to do
it off of an electrical sub panel. The subs i see are only 1 phase.
How to I tap into the main box? Do i still use a double pole
breaker? Single pole breakers only go upto 30 amps. I want to run 4
separate circuits off the new box. Thanks.
