I have a situation (In Central Florida), that a 3PH commercial service does not have any main disconnecting means. The POCO CTcabinet is feeding inside the building to (2) 225 amp MAIN LUG panels. Outside, there is no disconnect; only the CT cabinet. We will be adding a new sub-panel inside for additional space inside.

To bring this site up to code, it is my understanding that a disconnect must be added outside (the ct cabinet is 5 foot away from the edge of the building), and the panels need to be main breaker, since they are not adjacent to the disconnecting (or lack of) means. Am i wrong in my understanding?

What is the best option in your opinions to approach this?

You need a disconnect means inside or outside unless you have local amendments you don't need both. The disconnect means can be a main panel breaker. you may have an issue with how much un fused conductor allowed inside the building. contact your AHJ for what is required.

... The POCO CTcabinet is feeding inside the building to (2) 225 amp MAIN LUG panels. Outside, there is no disconnect; only the CT cabinet.

If there are two panels off of the CT cabinet, but still a total of no more than 6 breakers between them, the "6 hand rule" could apply.

If the 6 hand rule is being applied correctly, you would need to have your new panel fed from one of the existing panels. For example Panel 1 has 3 breakers in it, Panel 2 has 2 breakers, you can add a 3rd breaker to Panel 2 to feed your new Panel 3.

If your two panels already contain 6 breakers, then you either have to feed it from some other downstream circuit in a sub panel (if any), or install an overall main as you suggested.

If the two panels have more than 6 breakers (or for some other reason violates the 6 hand rules), you will need to bring it up to code.
