Thanks Tim, and now I'm embarrassed. Time for some background.
A guy calls me and says he installed a 14kW for a customer a couple of years ago. He said it was a 14kW and gave me the model and serial number. Says recently it wouldn't carry the load.
I ran the numbers to determine warranty status. Unit was never registered. He asks that I go check it out and make repairs.
I head out expecting to find a stepper motor problem. Instead the unit has a mechanical governor and it never clicks that I'm not working on a 14kW. I even glanced at the nameplate. It's a centurion by the way, not that it matters.
I guess it was the power of suggestion, the mere mention of it being a 14kW got embedded in my brain and that was it. I spent the better part of Saturday working on that thing, scratching my head and saying this makes no sense. I kept thinking unit must be overloaded, but its a 14kW, it should be able to handle this load. :confused:
Numerous Lights and televisions. This is a huge home.
In other words, the ATS breakers were all being used and supplying significant loads.
I could kick myself in the butt and ring the installers neck :eek: Instead I have to go back to the homeowners and explain to them why their "14kW" unit is bogging down.
I just can't believe I didn't catch this. Oh well. :mad:
BTW, I now think that this unit has been put through such a stressful load carrying workload for so long, (there have been numerous extended outages), that the now inability to carry a significant load is to be expected.
Can it be salvaged? Engine compression, voltage regulator, springs on the governor? All these areas have been severely taxed. So much for next Saturday.
Feel free to suggest any other potential problem areas to check. I'll research them all. It's personal now and its on my dime. Gotta try to make it right, within reason of course :D
