LOL...yeah..i'm starting to change my mindset from 'last few hurdles' to 'one hurdle at a time'.

Am I ok with this? https://www.inverterdrive.com/group/...0-203-H1F-P-A/

Out of interest, why is it that I can get away with it on a 13a plug if it states 21a input current? Is that because it won't draw that much in practice?
