RVing Tip of the Day

Keep your RV alive – Feed it the right voltage
By Steve Savage, Mobility RV Service
We were camped and our Progressive Power Management system cut off the power to our rig. When I went outside to check the box, the system provided me a readable code that told me why: The voltage to our camper was too low. What does that mean and why is it important? I’m glad you asked.
Everything in your camper that runs on electricity is designed to operate within a certain voltage range. Although it may vary by a few volts depending on the appliance, generally speaking the range is about 105 volts on the low side to 130 volts on the high side. When the voltage coming into your RV is not within those limits, things start to get hot. When they get hot long enough, they go to heaven. If things go to heaven, you have to pay for new ones and have them installed.
If you think of the power supply in your campground like a water system – with water taking the place of electricity and pipes taking the place of wires – you can think of it this way. So much water is available to the campground from the utility company and coming into a main. From there it goes down the pipes to the pedestal at your campsite where you plug in. When the campground is not full, not many people need water so there is no problem. You have all the water pressure (voltage) you need.
Now what about when the campground is full? If those pipes are not large enough to meet everyone’s need for water, there is a problem. The problem is low water pressure, or in the case of inadequate wiring, low voltage.
At our campsite, then, those wires were too small and our power management system was killing the power to protect the equipment in our camper. The voltage, varying greatly, was running between 118 volts and 105 volts in an unpredictable manner. I would guess it was pretty much in sync with compressors kicking off and on in our neighbors’ RVs. Should that happen? Absolutely not! It happens because the wiring system in the campground couldn’t carry enough electricity (current) to meet the needs of the equipment that depends on it.
So, if you get an idea of what is happening, shouldn’t the circuit breakers tripped or my air conditioner shut off? Unfortunately not. Breakers respond well to rapid heat rises, but will allow everything to continue merrily on its way when voltage is running low. Although low voltage is not good for any equipment, it most commonly destroys the relays in the air conditioner which feed power to the compressor as that compressor is a power pig, even when it’s working at its best.
When relays get hot for prolonged periods of time, the contacts literally weld themselves together. If you or a friend has ever had an air conditioner that did not shut off, after the fan had stopped running (you heard a continual hum unless you tripped the circuit breaker to the AC), that is most likely what has happened. If you have noticed the circuit breaker box (more correctly called the “power distribution panel”) has gotten hot or smelled like melting plastic, bingo, low voltage again. When I went outside our camper, the breakers and wires in my neighbor’s power pedestal smelled like they were melting. Same thing: low voltage.
So what could I do to deal with the situation? Not a whole lot. I guess I could have sneaked around and unplugged all my neighbors’ shorelines and killed their power so I have more. That would have likely brought me more grief than what I already had. There is no likelihood the campground was suddenly going to be updated (though I was told it is in the planning stages). Other than that, I stopped using my power management system and monitored the voltage with my multimeter. If my power dropped to 104 volts, I would have killed my air conditioner and made do with just the fan until temperatures and hopefully power usage dropped that night.
Of course, if I had known there was a power issue in this campground, I would not have reserved a site. It is a given that we will not be back next year as even at my wholesale rates, we still have to pay for parts like everyone else.
In the event you are new to the issue of low voltage and its effect on RV’s components, what should you do? The need for a power management system (not just a surge protector) is a given. If you don’t want to invest in that, buy one of the power monitors you plug into the receptacle on the wall of your RV and see what it reads around dinner time when power usage in campgrounds normally peaks. A monitor costs a great deal less than circuit boards or compressors.
A final thought about the dangers of low voltage has to do with the life of your companion animal. If you are using a power management system that shuts down the power to your rig in the event of low voltage (they all do), if you have a companion animal and left the air on to keep it cool, low voltage creates a life or death situation without sounding a warning. Just something to keep in mind, if you are concerned about whoever is in your RV when you are not there.
How common is low voltage? In older campgrounds, it is extremely common because they were often built before 45-foot motorhomes and 40-foot fifth wheels became commonplace. If by chance you write a review of a campground and experience a problem with low voltage, be sure to note it in your review. I intend to do the same when I write a review about the campground where we camped.

Dated your detectors lately?
No, we’re not talking about flowers and a nice dinner. Pull your smoke, LP and carbon monoxide detectors down and check their labels. Detectors are “good” within a certain date, and even if they seem to be “working” after the expiry, don’t risk it – replace them.

Keep that VIN handy
With electricity expert, Mike Sokol
Keep a photo of your vehicle’s Vehicle Identification Number (VIN) stored in your phone. Many times when you call the order desk for repair parts the first thing they’ll do is ask you for the VIN. Save yourself a trip out to the driveway or storage facility and keep a copy close to you. This one tip alone has saved me a LOT of steps.

Don’t let bees buzz you

Put a layer of window screen over the vent holes on your bumper plugs. Still lets the drain hose air out, but keeps the bugs away.

A comment on your #871 Electric low voltage. I have found a wonderful product called a Hughes Autoformer Voltage booster and Surge protector. I have monitored my power at all parks I’ve been to and this works great.

Good article about low voltage at many campgrounds.After experiencing this very problem at an RV Park in Wallowa,Oregon two years ago,I spoke to the owner about it as it had melted my amp cord end at the pedestal.He admitted the RV Park had electrical problems and claimed he would have it all “fixed”…by the next season…well…no “fixing” and he raise the monthly rent 25%. So no more of that place for me.RV’er beware of the electrical problems at many RV parks and the owners “claim” that all is hunky dory…many times it is not.

Propping up your slide is the worst thing you can do! Plus it is not recommended by any manufacturer!

Solve the problem with a Hughs Autoformer. If shore voltage drops too low it will “boost” the voltage being supplied to you RV. Especially useful in older parks.

can you recommend a simple power voltage monitor that can display the voltage continuously. An alarm for low voltage alert would be cool.

This has been a really inexpensive yet effective voltage monitor for me:

Regarding the article on “Propping up your slide-out”. As an ex RV salesman we did not recommend ever propping up the slide-out. In the event of a leaking or flat tire on the RV the RV will settle putting too much pressure and strain on the slide-out causing potential damage. If the RV is built correctly the slide-out will support itself adequately.

Hi Mike. Do you know if Mike of the “No Shock Zone” will answer electricity questions if I email him?
Thanks. Kevin

In response to the main article of Low Voltage at older campgrounds and RV Parks, I purchased a Power Master VC-50 Voltage Booster to use in those situations to eliminate having no A/C when it is most needed. My Progressive Industries HW-50C no longer drops out when it encounters any Low Voltage situation. Unfortunately they are no longer available but you could use a 50 amp Hughes Autoformer Voltage Booster instead.

Hi Chuck. That video of the C Class on its side. Do you know what caused the accident? It would be good to know, if it was something that could be prevented. Thanks
