RE: [CAD_CAM_EDM_DRO] Re: question for you electrical guys

Technically you are correct about the sizing, but practically I don't think
it's much of a concern. The switch in question is NEMA rated which means it
is really robust and would be quite difficult to overload. If you take an
IEC rated device and overload it you will have to replace it soon. NEMA
rated stuff seems to last forever.
