I just wanted to follow up for anyone interested. After running the devices
through the kill-a-watt I got these ratings:
3560 = 0.2 amp
3550 = 0.48 amp
2500 = 0.28 amp
3640 = 0.37 amp
Each device took about an extra .5 to 1 amp upon startup.
My lab is about 5 amps, so you guys were right on! I feel much better about
turning this thing on. My frame switch (2511) was bad, so me seller is
sending me a replacement. I have been building this thing for two months...I
guess another week of waiting won't hurt :)
