How long is a short time? There should be a tag on the bed near the junction box or cord that gives the voltage, wattage and amprage rating of the bed. Look for this tag and we will determine the requirements for this bed. I have not yet found your exact model of bed from Wolff System but I continue to search for it.
I have contacted the company but it's after hours there so I expect an answer tomorrow sometime.
30 seconds makes me think it's wired incorrectly so it's drawing way too much power. We will have an answer for you tomorrow. In the mean time what do you use to connect the bed to the 60 amp power source? I need wire size and conductors and what terminals you have the conductors connected to.
I believe I have given you the avenue to get the information you asked for in your original question. Now I want to see your bed operating. Remember, Green is ground, White is neutral, Red and Black are the current carrying conductors. It's hard to see in the picture just what is connected to what as the cord doesn't show wire colors. 4 wires are necessary and when you contact the number I gave you earlier they can tell you the proper amperage for this bed. It will work at the proper amperage, do not install a bigger breaker to get it to not trip. This will eventually cause a fire if you go big enough. On your cord in the picture it appears the center wire is not connected to neutral or ground. If an outside wire is connected to either or both of these wires that is your problem. Both outside wires connect to the red and black wires in the unit. White and green connect to the same colors in the cord.
If you feel I've answered your initial question please accept the answer so I get paid. I will continue to work with you to assure your bed is up and running. Thank you for this chance to help you with this problem.
Good job...... You have the information you need now. The bed needs to be connected to a 30 amp single pole breaker, not a 60 amp double pole breaker. By connecting it to the 2 pole breaker you have supplied 240 volts to the bed and possibly damaged the controls. Lets hope everything is OK. The 3 wire cord is correct as it is probably a 30 amp 120 volt cord such as is used in the RV industry on camper trailers. In your receptacle where the bed plugs in you have a black, white and bare wire. Black goes to one side, white to the other and bare to the ground. Normally the ground is a green headed screw, white is a silver screw and black is a copper colored screw. If the connections are different just send me a picture and I'll help you straighten out things.
Thanks again for this opportunity to assist you with your problem.
