This is really a question. Are there any recommendations for 2pin vs 3pin plugs for IT equipment.
When setting up a laptop, you might have 2 screens, a laptop, a dock, all with their own mains supply.
My advice would be either have all psu with 2pin plugs or have all with 3pin, but never mix, some with 2pin, others with 3pin.
What do other people think and why?
Assuming all devices involved passed regulatory testing it doesn’t really matter all that much.
It’s just that there have been reports of some problems when mixing them, that is fixed if they are not mixed.
You don’t need to mix for that, you just need an ungrounded one with high enough leakage, the legal limits for that are unfortunately high enough to be perceptible for most people. Actually mixing in a grounded one may help in that case.
Pretty sure that can also happen without mixing and definitely with multiple different floating psus involved.
I think that’s a very bad idea if the original PSU had 3 pins.
Ground is there to protect you in case of short-circuit, current will flow through ground instead of your body if you touch the appliance (if I remember correctly, 10mA are enough to kill you).
I meant is the psu was designed to 2 pins, have 2pin designed PSUs for all devices, or have 3pin designed PSUs all round.
Not plug a 3pin designed PSU into a 2 pin plug.
