lighting panels

[Simplot]

I have been given the job to remove an old 112.5 kva transformer that has been feeding 2 lighting panels. I will be adding a third lighting panel. The two exsisting panels have their own breaker. The primary side also has a breaker. The new panel will have a main breaker. All three have different lenghts. Question, how do I tie all three panels into the new 112.5 transformer to the three panels???? :?

as long as the sum of the ratings of the mains of the three lighting panels are less than 125% of the transformer secondary current you are fine.

if not, you need some kind of OCPD to protect the secondary of the xfmr.
