I see a lot of talk about devices not rated for high amp. I get that. I also feel it's somewhat of a gimmick - or just call it a place of confusion for john q public.
In the US, most house circuits are 15A. I personally have never seen a power cable go through a wall just to one socket. it's always a daisy chain through a few rooms.
My Seedan/CMARS outlets are rated at 10A. that is a ton of juice. The idea that someone truly needs a device that can handle 20A or more... always makes me shake my head.
Perspective - a blow dryer is 1500w. (ymmv). 12.5 A. Now. I was a hardware engineer when I got out of college, specializing in AC/DC. When we built something we used the 'factor of safety' rule. thats 10% over design. Your 1500w hair dryer really puts out 1350w at max. 11.3A
The 10A rated outlet is 10% off as well. it's really 11A. I realize we're close here but this is just point of discussion - spending tons of money to get a 20A rated outlet or relay is nuts since the circuit is a 15A outlet to begin with! What we need to be looking for is 15A rated outlets!
