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.
Are you dealing with aliexpress or the store? Escalating is straight up necessary - one relay board I bought had the MC enable pin grounded and after fixing that the relay pin would flicker high on boot. No idea how that got to production as without modifications it didn't work at all, then with mods only worked badly. The store first didn't understand the issue then accused me of user error. Escalation was my go to
Thanks, I'll try to ensure i'm dealing with ali and not the seller.
