I bought a switched PDU from aliexpress, and i broke the rule of buying from ali... I tested it! The Live and Neutral wires on the PDU are crossed over.
I've attempted to return it, but aliexpress keeps denying me saying its a grounding problem with my test setup... hence why i stuck the fluke in directly for a direct illustration.
Sure, and if they used a type F plug on the device I'd agree with you, but they went with NEMA 5-15, which has polarity requirements.
