how much unloaded and how much at 80% load? OK, I have installed more than a few trans, and I want this thread to be kinda of a poll of what you guys expect out there, and what is out of bounds. I have seen input voltage at the plug anywhere from a very low of 102 volts to a fairly high of 125 or so, but 90% of the time I see 110 to 120. I installed 3, 900 watt trans from Garden Light the past week, 12-15 volt, same job, all imput voltages from 115 to 118 on 3 different breakers on GFCI outlets outside. I am pretty sure these are made by jefferson, I may be wrong on that, but they look identical to the coppermoon units. my experience with these units is at 115 volts and up imput, they tend to test out unloaded at about 15.2-15.5 or so on the high tap and come down to 14.5 or so loaded up to 80%. This is fine with me on most jobs, as with a 3 volt drop I can design around 10 and 12 guage, 100-120 foot runs and 80-120 watt loads per run, and be able to add a light to a run if the customer wants to add after we're done and they see it. So imagine my surprise on all 3 units starting unloaded at 14.5-14.6, and 70-80% loaded dropping to 13.3-13.6. Luckily I tend to over use wire and under load said wire, so it was fine, but barely, and no real room to add lights on most runs. I am used to seeing a volt drop or so on loading, but not starting voltage on a new trans already down a half a volt unloaded, unless starting voltage is 105 or lower. What do you guys see out there and what is "right?"
