AC electrical guys look here.

My wife has a tanning bed. I Wired up special plug in a spare room when we moved in the house years ago. After a year or so, she never used it. (It did work fine during that time) Now we are going on a trip and she wants to get a tan before we go. She turned the bed on and after about 8 minutes, it blows the breaker. This is a 30 amp double breaker. (220 volts)

I hooked my AC clamp on one wire and read 36 amps. The bed has thirty 100 watt bulbs. I'm thinking that's 3000 watts divided by 220 volts should be little over 13 amps. How could it be drawing 36 amps? I freely admit this is the first time I have ever used the AC clamp meter. But I think I'm doing it right.

There's two burnt out bulbs in the bed. Would they draw any power? There are some others that work, but have Black on the ends. Would they draw more power?

Any guesses?

Remove the bulbs one by one, meter again. Your math looks right.

You're from Florida and she needs to tan? Dont you people look like worn out shoe leather and skin cancer all year anyway? Or are you both so old and pasty its impossible to tan the varicose veins?


Asking because science.

It doesn't say anything, you have to read it.

Sorry, I had to. I can't find the data plate. The bed weighs about 400 lbs. and I can't move it to see the back. (This thing is a real PITA)

I was thinking of this. If I pull a number of bulbs, I would think it will go down. But I don't really see how the draw went up from ten years ago.

Double check your clamp meter with a known source,you should not be drawing more then 14amps
How hard is it to take apart the bed to look at the connections?
Has the bed ever gotten wet?could be corroded wiring causing more current draw
Is there a spare breaker you can swap to see if thats bad

And fuck pirate is slacking lately
Nobody has asked for pics of wife

What kind of 100w bulbs are they? Incandescent? Some kind of fluorescent? Halogen? Is there some sort of ballast/driver or just a bunch of sockets? Nameplate would be a huge help.

Typically there will be vho ballasts and lamps, a timer, at least 6 cooling fans, a timer, and an external squirrel cage fan for the user. The ones my mom owned ran at about 24 amps at 240v. The ballasts will cook and short the windings internally. PITA to replace them, but I scrapped those fuckers 15 years ago and ended that waste of money for her.

I'll ask my wife tommorow if she has any idea. She managed a bunch of tanning salons owned one for a short period, and currently owns a buisness in the industry.

Sidenote: it's amazing how many girls with memberships will go to multiple salons a day, every day.

This place is going down hill.

Find the wiring panel look inside and start disconnecting stuff.

^ this. The beds I've worked with have a ballast for every 2 bulbs, a starting capacitor for each bulb, plus all the other electronics. One failed ballast will cause all kinds of issues. They are a PITA to service, parts are not always easy to find and can get pricy. They sell used cheap because people realize how expensive it is to own and maintain them.

I can't believe I forgot about the fans. Duh. When you turn it on, it makes tons of noise. (Fans) I suppose that would run the amps up. But still, it use to work with that breaker. I'm sure I checked the data plate when I installed the receptical/breaker. When the ballasts ware out, do they start drawing more power?

If your fan makes a ton of noise start there A bad fan with bad bearings, binding, etc will draw a ton of amps.

Hot tub?
Welder?

Pics of wife using the machine would help in diagnosing the problem.

Nothing added to that line. And the amp meter was right at the bed, so anything that was on he line would not show up. Assuming the amp meter was right, I would guess that 36 amps would kick the breaker after a bit. (7 min) or should it kick it right away?

To all you haters, a tanning bed was not bad when my son was living with us. All his girlfriends used it. I don't know how many times I went on our screened in porch to find a naked 18 year old out there. Lol. My wife dint like that much.
