So, after 5 days (and STILL) no street power, I decided to rewash and dry the clothes that had been sitting in the wash tub since the power went out.
My generator is a Generac XP8000E with 8000run/10000surge. It is one of the "better" portable generators in that it is intended for safe use of sensitive electronic equipment like high efficiency furnaces, computers and televisions. It is properly back fed/direct wired to panel by an electrician. Let it be known I was extremely reluctant to use the dryer but felt it was within a relatively safe parameter to do so.
I made sure the only thing on at the time at the panel was the dryer. My no load voltage is 241 and 63hz. I assume generator voltage is tuned on the high side due to no load. Using a brand new Fluke 325 amp clamp, I would keep an eye on the wattage, volts and amperage.
Dryer set to normal mode, medium heat, it went on its way for the setting of 45 mins...fingers crossed. It lasted 38 mins.
With 7 mins left, the dryer stopped tumbling, but it kept timing down. Lights were still on (on the dryer panel) and the generator still produced power - no circuit breakers popped.
load per leg
(black 120v) 22.81amp (x) 120 = 2727.2 watts. 58.9 hz
(red 120v) 25.08amps (x) 120 = 3009.60 watts.
Total combined 5746.80watts running
when the dryer stopped, I cancelled the remaining time and tried starting over at at lower temp. Lights came on but no tumble, no noises...just lights on the panel and inside the drum
I will retry when street power comes back on. I am hoping it just timed out? perhaps the Hz were too low? lowest was 58.9hz running, but i was running the generator at 75% capacity of running wattage (5700 out of the 8000- still with an additional 2000 surge.) Is there thermal protection that timed it out?
if the generator wasn't large enough, wouldn't it have either tripped something right away?
where do i look/go from here? thanks, Bob
