Default IEC mains connector poll

Which way up do/would you mount IEC mains connectors (earth up or earth down), and are you in 50Hz land or 60Hz land?

I think it'll be divided about 50/50, and have a theory why.....

I have seen both left, right, up and down.

I prefer down - don't know why.

Down mostly but this has to do with other things.

My oscilloscope up (built-in fuse holder), Japan
LCR bridge up, Brittish!
Signal generator down, Sweden
Frequency counter down, Sweden

A rather unimportant question but I'll prefer to have the ground down. Feels more natural.

Ground up usually when I'm installing the connector, as it seems easier to connect the lead 'blind' that way, but I have gear with them all ways round. Right-angled line sockets make a difference to what's best. (50Hz territory).

Down....60 Hz.......aesthetics.....

H-P doesn't seem to be able to make their mind up, so why should we?

Default Whichever

I do it the way which is easiest to make the cut-out so the AC inlet fits cleanly. Typically I'll use a dremel and a file, whichever (top or bottom) of the dremel cuts turns out worse I'll file for the angled edges and use it that way so it fits neatly.

However, in the one instance of using frontpanelexpress.com to make a rear panel cutout of exact shape, I put the ground on top. Only reason was that this leaves the writing right side up on the inside connectors so I felt like it was supposed to be like this; and you could read "furutech" or whatevever the name was across the top of the inlet on the inside. cool.
60Hz.

60 Hz, down unless there's a compelling mechanical reason to do otherwise.

(BTW, if there's a correlation, I'd guess tube versus transistor more so than 50 versus 60)

Default Why Use the Damned Things At All???

In this time of mega-bucks IEC plugs why not hard wire the mains cable? sounds way better than any IEC plug and socket!
