Re: What's this mains plug with live/neutral horizontal when earth is at the top?


 

There are also Boost/Buck 208/240 transformers for industrial use. I had to install one on a pipe bender for a local company. The machine had always been wimpy, running off 208, but it worked properly at 240V. The 'industrial' electrician that wired it when they move had wired it to a 120V circuit, even though he used the proper outlet. A new breaker, and a boost transformer restored operation, and doubled the production rate. Keep in mind that the difference is over 13% and it can cause problem on some equipment.

Do note, though, that I¡¯ve seen designs that have an input transformer with a 208V tap, and can be wire-strapped for either 208V or 240V operation.

Now that I¡¯ve mentioned it, yours won¡¯t have such a tap, or will be already strapped to 240V. Otherwise, of course, you¡¯d have the oddball device with such a tapped input transformer and it¡¯d be set for 208V, requiring restrapping for 240V
but such things never happen when you are prepared for them.
