CB, MC, OLR COBMINATION SCCR VALUE

UL_CoC_3RT2_2_202101210940587334.pdf

I was going to upload the above 2 files, but it's possible to upload only 1 file.

There are two proposals.
1. Calculation of SCCR value by combining CB+MC and CB+OLR
2. Calculation of SCCR value by combining CB+MC+OLR.

For CB, UL489 should be applied.
When the second plan is applied, the CB rated current value increases compared to the first plan.
I would like to apply the first proposal, but please answer if it is applicable.
