[time-nuts] 5061A AC Power connector

[Peter Bell]

Ah, OK - the last time I had to do any connector abuse like that the keying
was a little different - there was a tab on the insert and a single keyway
cut into the shell - if you wanted to change the polarization, you had to
file another keyway in the shell and rotate the insert.  It sounds like the
connectors you are talking about make it quite a bit easier (and far less
toxic).  It also sounds like it might actually be an approved procedure -
which it certainly wasn't with the connectors I was using :)

Regards,

Pete
