I'd use the 140W figure. It would be rather expensive to have the electrician out a second time to add a circuit. Not just for the electrician, but also the business disruption involved. Running three 20A circuits makes it all straightforward. Your and my observations tend to confirm that it's not higher than 140W.

I found it!
I was moving around a seg that had a console cover on found this:
100-240 VAC 50-60 Hz 2 AMP So here its from Seg its label!! [IMG]C:\Documents and Settings\User\My Documents\My Pictures\2011-05-15_18-18-31_852[/IMG] Quote:

If it's greater than 1A, and they don't give more than one digit, they'd label it 2A. 2A at 240V would be 480W, which is nonsense. Even 2A at 120V is 240W. I would wager my own money on 3 20A circuits, 12 outlets per, never tripping a breaker, even if you managed to start them at the same moment (as in recovering from a power outage). But if you want to go for maximum paranoia, 4 20A circuits, 8 outlets per, you can do that. Unfortunately, measuring (and describing) inrush current is tricky, and I just don't have the time to do it. And very brief inrush surges are not particularly relevant. But we can look at a typical circuit breaker's data sheet! Circuit breakers are rated to trip at the rated current -- eventually. A GE DES-012 20A AFCI breaker, with a 100ms inrush current, won't trip at 4x the rated current. Even a 1 second surge, won't trip up to about 3x the rated current. Circuit breakers work on a combination of thermal (delayed) and magnetic (instant) detection. Above a certain point (depending on conditions) the magnetic trip will trip it fairly quickly, but that's higher than these currents. Bottom line -- I'd still just go with 3 circuits, 12 outlets per. The worst that could go wrong is if you plug in all your Segways during a power outage, and you trip the breaker when power comes back on. In that case, plug in half of them, reset the breaker, and go plug in the rest. But I don't see how that would be possible.

The messenger has nothing to fear, and did a fine job.
