Technical boundary FAQ
Which ratings must match across an HV connection?
State the exact subcategory, application platform and project stage first. Then provide Voltage category, Continuous / fault current, Ingress / sealing, HVIL / mating system, Shielding / EMC. Tie every value to a specific variant, test condition and public source; keep unknown values explicit and close them during sample, PPAP or contract review.
