You can get dedicated USB testers for not a lot of money, but to be honest if you want to test a USB outlet just plug in a cheap USB light.
All you’re testing is a 5v dc supply.
If you know which pins on the plug are the power and which are the data transfer... get an old usb lead, cut it down to the individual cores and use a multimeter to verify 5v + or -
I’ve never actually checked any I’ve fitted. I assume the customer would soon say if it wasn’t working, then it’s a trip to the wholesalers.
BUTCHER!!!!!!!!!!!!!! You will give us electricians a bad name We adapt and manipulate I'll have you know.Thanks for that and hadn’t even thought to butcher a lead what a simple solution
does anyone test these in any way if so what do you use. Or do you just test the 13a sockets and make an assumption that the usb skts are working ?
plug your phone charger in....sorted
Better than plugging your far more expensive phone into a potentially faulty port.
My USB socket was only outputting 2.5V after an IR test. My tenant didn't use it so I don't know what it was like before - but still I'm highly suspicious that the IR test fried it...Interesting question, USB sockets are SELV supplies so does anyone routinely measure IR to confirm isolation? 612.4.1 requires insulation resistance measurement for SELV, one to think about.
Some do, some don't.Not had any experience with USB sockets does doing an insulation test at 500v to earth fry them or is it only between L & N?
Do I take it then a 500v test to earth is safe but between L and N could not be.Some do, some don't.
You'd need to check what manufacturers state for their accessories. If unsure then just do L&N to E.Do I take it then a 500v test to earth is safe but between L and N could not be.
