Would it be good design practice, or a waste of money, to have this hand dryer on it's own seperate circuit? Doesnt draw that much depending on the voltage.

Another example of useless manufacturers instructions. :rolleyes:

Yes, I'm trying to fight this. The engnerr is saying a dedicated circuit. He's obviously going with the manufcturer recommendation. How can I convince him to go away from what the manufacturer recommends. They say it's REQUIRED.

I think I'll email the manufacturer now and ask them to forward my email to thier engineer. Besides the power consumption listed on the spec sheet should I add any other electrical calc info that could counter the dedicated circuit requirment? Thanks.

Email the manufacturer but if the instructions are part of the listing then you'll need to follow them even though that's pretty stupid.

Good point. I'll add we are using a 20A circuit. That may help. Could it be they want a dedicated neutral?
 
The contractor thinks how I can save money, time.

The engineer thinks what can go wrong. What if failure of one dryer trips the breaker and both don’t work and people are caught with wet hands or God forbid pants.

Both have a point. Question? How much it will cost you to go there ASAP during warranty to correct this or fix it so it never happens again. When one dryer does not work there is usually no urgency.

So it’s not just the wiring is different if it’s 120v or 208v the actually dryer is different as well?

From the details you provided the output would be the same at either 120 or 240 volts but the current at 240 would be half that at 120 volts. At 240 volts you could put 4 of these on a 20 amp circuit which makes the individual branch circuit requirement for each unit dumb.

I'm sure it's some form of CYA by the manufacturer. Some irate contractor somewhere probably tried to put 6 or so of them on one circuit and filed a suit when it came back to bite him. Or something like that.

So it's only wiring difference( and breaker) for 120v vs 208v? It would be one phase conductor vs. two phase conductors??
