TopWorx is informing its customers of this circumstance in accordance with Section</br>21.21 (b) and 50.55 (e) of 10CFR21. </br>Applicability: This notice applies only to the C8, M8, and H8 series of switches.</br>Discussion: A potential nonconformance was discovered during product review when X-Ray analysis revealed a small piece of loose solder inside a completed C8 switch. Investigations revealed that the cause of this defect was the amount of solder used to hermetically seal the switch and enclosure together. Under the right conditions and circumstances, excessive solder on this specific switch model could potentially bridge between a circuit connection and the internal surface of the switch enclosure causing a high potential (Hipot) failure.</br>Extent of Condition: No other series of switches are affected by this information notice.</br>Actions Required: The recommended corrective action for installed switches is to continue monitoring for ground fault indications. If you do not currently monitor for ground fault indications, then a resistance check using an ohmmeter from each contact to the case to ensure no continuity to ground exists. Any switches exhibiting continuity to ground should be returned to TopWorx for replacement.</br>10CFR21 Implications: TopWorx requests that the recipient of this notice review it and take appropriate action in accordance with 10CFR21.</br>Customer notifications (Quantity purchased and Customer Purchase Order numbers):</br>Nuclear Logistics Inc.</br>(Qty 2 - PO #NLI57759, Qty 1 - PO #NLI-50192 REPL)</br>Control Southern Inc.</br>(Qty 10 - PO #X230280199, Qty 24 - PO #X230303436, Qty 1 - PO #X230315950, Qty 14 - PO #X230336922)</br>Ralph A.
