Question re: electric junction box
Howdy all. Here is a question for the boys....
Since I have been here in CA, I have been using what seemed like a LOT of electricity. The dial out on the meter would just spin and spin; even when there was nothing actively running in the camper except the fridge/freezer.
Park maintenance agreed something was wrong with it. The electric man came over today and said it was running on 120v. He changed it over to 240 and said it should help, but he thought it looked like it was "surging" at times and that something in the camper could be making it do that. He suggested that the batteries might be the culprit. Does this sound right? I know nothing about electricity, except that I have to have it!
Let's hope the electricity bill goes down...
thanks,
t

Steve and Tara,
That sounds really weird. The only thing I can think of that might be drawing a big load would be your hot water heater. If you have the electric element on it might be causing a big draw. But I know next to nothing about electric either. We have some electric folks here on the MOC and hopefully one or more of them will step up and straighten me/us out.
Please let us know when you find the problem.
Dennis

I lost my converter. The regulator failed and over cooked the battery. The only way to tell what is causing the power draw is to use your circuit breakers and isolate the circuits buy shutting a breaker off one at a time and see what happens with the current draw. The change from 120 to 240 should not make a difference because your trailer is still only 120.
Good luck and let us know what you find.

John is right on, could be a bad battery, converter throwing a charge into it, (over charge) but the largest loads are resistance, hot water heater being one, electric heater, another.
Turn everything off, then on, one by one and watch the meter.
You really need an electrician, or someone with an amp meter to check your trailer out, checking each load.

We have the progressive industries PT-50C surge protection That gives a digital readout on both legs of the 50 amp power at the CG. Power pedestal and records the current the camper is drawing. You post would indicate something wrong at the pedestal and the PT-50C would have helped in determining that. We can tell you that the hot water heater on electric(3400) draws 12 amps, The furnace 10 amps,the on board vacuum, 8 amps. The fridge does not draw much at all. With the hot water tank on propane, fridge on electric, and normal power usage in the camper, Tv on , Various lighting, etc we will draw 2 amps on leg 1 and 4 amps on leg 2. Our electric bill last month, In Centrial Florida,The furnace may have run 2 or three nights, we ran a electric heater most every every night on high, 9.62 amps(the bird) and ran the hot water tank on Electric all month ..the bill was 73.42. Now I think that is high for a 400 square ft Camper.

Ours was $126.00 at .13 a KWH, 1 freezer, H.W. tank, two refrigerators, A/C some days, heat some nights, no propane useage except cooking. Mine is high, but no propane furnace use.

Thanks all. Steve doesn't come to visit until the end of Jan, so I will just have to deal until then....
I don't think it is the hot water heater. I turned it off when I left for CA on Nov 17. The only thing running was the fridge and the little stand alone freezer. Everything else was off and unplugged. My bill for the month of Dec was $67 and I wasn't even here! Park guys are really good and have been just charging me a flat 50. Steve says he unhooked the battery before we left.
Could the problem be the converter?

If the Battery is not connected, and the circuit breakers are labeled, find the one marked for the Converter or battery charger, and turn it off, then check the dial on the meter. If it slows down, than either you are trying to charge the battery (which is disconnected) all the time, or you have a bad converter. Hope that helps.

$67 isn't bad.
How is your new career going?

If batteries were not connected cannot be converter because it has nothing to charge, it cannot see battery voltage resistance to give it any charge. If hot water heater heater was flipped off as well, soemthing else is pulling a load.

I agree with Bob, trip one breaker at a time and see if there is a big change. Should be able to at least tell which circuit is eating the juice. You said Steve disconnected the batteries. Did he do it by the switch or remove the cables, and possible one cable is shorting out.
Where in CA are you.

Don't know about the battery; will have to check.
I am in southern Ca; San Bernardino/Colton area. After the rain quits falling; I will check each breaker and see if I can ascertain the "guilty" breaker.
Keep you posted...

Does the converter use a full bridge rectifier or a thysistor rectifier?? IF its a thysisor bridge, i'd bet the converters where the drain is.

If it is the converter, seems you would hear the cooling fan on it running all the time. IIRC, the fan runs proportional to the amount of current draw. You know, those electric meters do go crazy sometimes. I would have them pull the meter and swap it with one from another lot.

This may appear as a dumb question, but have you tried disconnecting your shore power cord from the park pedestal to make sure it is not the park service that is the problem? If the park pedestal has a meter and you unplug from that pedestal that meter should stop. If it doesn't then it is either the meter or the pedestal itself that is shorted. Don't rely on the park maintenance to disprove the park equipment. Chances are they will side on the park's equipment over yours.
If the problem is your's, when you throw the breaker for the converter does the problem go away? Are you still getting power to the 12v lights? If you are, the batteries are still connected. Disconnect them and see if the current draw is back when you switch on the converter. Make sure you isolate the battery cables so they don't short out. If the current draw comes back when you apply power to the converter, then the converter is the problem. A shorted primary should trip the breaker so I doubt the rectifiers are shorted in the converter. Could have a shorted secondary or capacitor that is leaking current. Either way, the converter will need to be replaced.
If switching the breaker to the converter does not affect the the draw, then the converter is not the problem you need to look elsewhere. I would then throw the main breaker to see if that removes the current drain. If it does not, then you have a short between the shore power and the breaker panel.
Hope you are able to find the problem and fix it.
Good luck!
