So section 7.4.2 in the OSG (Currently page 93) says that Band 1 data cables and Band 2 mains power cables need to be 150mm apart from each other, except under certain cases defined under sub section (a) like where they are enclosed in a separate conduit, are of mineral insulated type, etc...

Just teared down a cheap USB power supply from a USB hub, and to no surprise :rolleyes: the isolation between the mains primary side and the SELV secondary side was suspicious at best. Not only did my non contact voltage detection stick react to what should have been the separated isolated 5V...
