Hand Dryer

It looks like it uses 8.26a if on 120v (115), 4.13a if on 240v (230), or 3.73a if on 208v.

So, for 208v, you obviously use the 240v connection and simply get a bit less power.

Two heater elements make dual voltages easy, but a dual-voltage motor that small?

Ok. Don't you have have to keep the circuit to no more than 80% of the breaker rating? Two dryers on a 120v 20A circuit would be 16.6 amps

No. The hand dryer is not a continuous load so you could load a 20 amp circuit to 20 amps. Requiring an individual branch circuit for something that draws 4 amps is dumb and a waste of someone's money.

this is interesting - I like the interp of 10 years ago from Mod GD

That is interesting I might be able to argue that "dedicated" branch circuit for dryers means the circuits can contain hand dryer loads ONLY. Although it does say EACH hand dryer requires dedicated circuit.

Personally, I always provide a dedicated circuit for hand dryers. Yes, it would work fine for this hand dryer but if they replace it with another one then it would be an issue.

Also, its a motor that will likely get dirty and less efficient overtime and could draw more power. Last, if they were used at the same time and its a longer run then could definitely trip.

The cutsheet says 8.3A @ 120v.

The cutsheet says 8.3A @ 120v.

By code you have to follow the manufacturers Installation instructions. I agree that it makes sense to try to save customer money where you can. I would bid it based on one hand dryer on a circuit even though I know someone else will come and bid it with two on a circuit and not give it a second thought!

I was referring to the 240 volt load.

If the length of the runs are excessive, you could consider a sub-panel near to the point of use to still be able to follow the manufacturer instructions of each appliance having its own circuit.
