Because I buy somebody's switchgear, they used folk lugs for CT and ABB test switch. I want to them to change to ring lugs. But they said it not UL.CSA, NEMA, IEC..... forced.
That is why I looking for the standard.
Hi all, could anyone tell me which kind of lugs used for CT secondary if the installation is to be to UL requirements or CSA? I know should be use ring lugs , but where is the UL or CSA standard? Could you send to me the link address?
