Generator interlock kit

[Blaze75]

Hi Everyone.

Question to the group. I have 2 x 150A panels. I currently have an interlock kit to one of the panels which services my main floor and sub panel basement circuits.... I am now looking to provide coverage to my other panel pictured on the left. In order to do this.... Do I just install another 30a breaker to the panel where my existing interlock kit is installed in and install another 30a breaker on my other panel?

Thanks,
Jeff
