who I believe is a supply house. We were informed by GFI that one of their customers had 9 failures and requested immediate action. We were never provided end customer’s information. Around the same time, we began to see a high failure rate during our internal testing. This plus field failures culminated in a full design review and change, attributed to the fusible plug tip angle. Since change, we have seen 0 internal failures. I will also note that even prior to change, all shipped fusibles passed internal FAT.
