[time-nuts] AC Connector On HP 5061B

[Jeffrey Okamitsu]

US is similar regarding the lashing together of earth and ground for single phase power. However, current US electric code is very specific about which terminal of the AC plug is wired to "hot" and which is wired to "neutral".

That critically depends what country you are in.

In the UK you can normally safely connect yourself between neutral and
earth, as neutral is "always" bonded to earth at the sub-station.  
There
may be a few volts on neutral due to phase imbalance in the three phase
supply and how far you are from the sub-station, but normally that's not a
problem.   I really wouldn't like to connect myself between live (nominal
230V over here) and neutral though!

I don't know the wiring rules in US well enough to determine how
"safe" this
would "over there".

By the way...I know that for single phase AC the assignment of "hot"
and
"neutral" technically doesn't matter...but I'm a purist...
 
Thanks.
