[Arcadia]

What is the correct answer for the Electrode configuration selection for typical electrical equipment. my thoughts are below:
Panelboards (VCB)
Distribution boards (VCB)
Switchboards (VCBB) 20/20/20 in
Switchgear (HCB)
Typ. Transformers (VCB)
F/NF Disconnects (VCB)
UPS-PDU-RPPs (VCBB)
ATSs (VCB)
