Query on power cable with IEC C13 and US 2-prong

While @ditusa is correct that double shielded devices do not require a ground, the double shielding mark is absent, and internally it does not appear to be double shielded. Also, internally there IS a connection from the ground pin to a chassis screw (based on a picture).

Having said all of that, the chance for contact between the power and chassis exists only at the 200mA fuse. Everything else looks very well insulated and I’d say that the chance of an actual Hot to chassis fault is nearly zero, barring immersion in liquid.

My Luxman B-12 mono amps from 1976 have a two prong plug, no ground. 😎

@ditusa  I have a Luxman 507ux, and it is also groundless.  I'm also not convinced this is appropriate for the US.  It's not rated as double insulated or Class II, and the fuse and other wiring could, in theory, come into contact with the chassis. 

I'm afraid I'm not knowledgeable enough in regulatory compliance to know if this is as it should be or not.

@erik_squires,

My Emotiva XPA 1 gen 2 mono amps from 2016 have two prong plug, no ground. See below: 😎

Read your owner's manual. If the list of "what's-in-the-box" states 3-prong power cord that means the unit is made for sale in the US and Canada. 

If the unit is double insulated (I doubt it) then there will be no continuity between the IEC receptacle's ground pin and the chassis. If there is (which I am sure) then you got the wrong power cord.
