Some ballasts either have a jumper you can move to different voltages, or different screw terminals to attach the incoming power to.<a href=showthread.php?s=&postid=11687297#post11687297 target=_blank>Originally posted</a> by CorbetJackson50
and im not quite sure what munti tap is, i assume more than one bulb per ballast, or something with how its wired
With most electrical devices the voltage can swing 10% in either direction without problems. My house is 120/240 witch would be out of range.
