I have a dough mixer, that the name plate says 240v/17amps. I think I need a buck/boost transformer. The panel is 120/208. But one of the other electicians thinks it will run ok with just taking 213v from the 120/208 panel. 213v what we are getting from A-B legs. I think it will ruin the motor. Any thoughts?
To boost or not?

You must always use nominal voltages when selecting equipment and supply voltages.
I would use a 120/240-16/32 buck-boost to go from 208V to 236V

If you end up smoking it because it isn't dual rated, you'll be the one buying it. Set a buck/boost if you have to and charge accordingly. I'm sure the manufacturer would say the same thing if it's not dual rated.

I know the piece of equipment that you are connecting is straight 240 volt, but keep in mind if you run across a piece of equipment that is 120/240, take care that the leg requiring 120 volts to neutral is not the leg that you boosted. You can let the smoke out of it if your not careful!

If you dont boost it wont the motor work harder to make up for the differance in voltage?
It would be the same as a "brown out" and would eventually burn the motor up unless it is dual rated 208/240 volt
The motor would draw more current to make up for he decrease in voltage. The motor should still work, but the life would decrease do to the added heat from the increased current. Unless of course the motor is dual rated.

I have done a number of commercial kitchens. I get real hacked off when I see equipment rated only at 240V. Don't these manufacturers know by now that the real world is 120/208V for most commercial kitchens??!!
