Hughes autoformer versus buck and boost

[paintman607]

I read all the posting and all are very interesting and informative as with all postings on the site. I have learned a lot here through out the months that I have been here, I went to a different electrical warehouse yesterday and got a total different answer about bump and boost and line voltage. Kinda like going to the doctors. You always need a second opinion. This EE told me a bump and boost will always BUMP your voltage to the set percentage you have in the transformer. In other words if you are at 120 volts at the box you will now get 130 because of the boost percentage. If you have 110 you will get 120. He says I need a line conditoner. I now say I'm buying a hughes autoformer. To many different things can go wrong with so many different answers. Thank you all for your comments and helping me understand the other side of the story.

That's correct and unless you automate it's operation you would have to monitor the voltage to determine when to connect it, an impossible situation. I think you'll find your going to need either a 1.2KVA unit for a 50 amp service or a 0.6KVA for a 30 amp unit. Keep in mind that the autoformer will throw off heat depending on load so try to locate it in a cool place or where there is ventilation, that is if your going to hardwire the unit. Good luck.

RJ, Thanks for reminding me about the heat situation. Sometimes the most obvious problem can be forgotten
