Yes I hooked mine to 220v. The reason for this is because elements increase in wattage drasticly when you go from 110 to 220. The wattage doesn't double its more like 2/3rds. Example 500 watt element on 110 is aprox 1500 watts on 220. Wire your elements in paralell the you can add or subtract elements without alot of wiring changes and it's gonna give you more heat faster this way. Amps start with a 30 amp box and then down size fuses till they pop then step back up one size or get an amp meter and know for sure I recommend the later. Are your elements labeled? what is the wattage.If you don't know then start with 4 and see how it goes, don't trust you controller at first put a manual thermometer inside and compare to controller for a while then tweak controller. Don't be supprised at the temperature swing you see home oven controllers aren't designed to hold precisely but they can be made to work if you toy around with them for a while.
