I don't know them at all, lol, so that is likely as totally wrong as it sounds.** **Just got a reply from the girl we bought it from and she asked her boyfriend abt the breaker the outlet they hooked it up to was on and he said 'double 50 amp'. And they are the same as this one we just bought. The best thing abt this one is that my bulbs from the one we blew the ballasts on are still good, the fans and timer are good and all the parts like the cover, trim, acrilyc, etc are in great condition. We didn't pay a lot for this one but I can't afford to buy another one if this doesn't work out. And for whatever reason, tanning bed manufactures don't make the info easy to find like I thought they would have ! Lol. I am now obsessed with making sure it is right before we hook it up. (And I soon learned the ballasts would be about $60-80 each and I would need 8 and that was more than we paid for the bed.) What we didn't know, is that my dad had changed it into a 220 at some point before he passed away 6 months before then. It ran on 110 and we plugged it into the outlet that my mom knew to be 110 and it blew all the ballasts. I probably seem obsessive about it but 2-1/2 years ago my mom and I split the cost of a used tanning bed.
