The long term residents in the park I'm at now have told me of power problems here. Since the real summer is approaching, I'm expecting at some point air conditioners will go on, and likely there will be voltage problems. Invested in one that will turn back on if the power returns to normal.
Surges are rare, but voltage fluctuations are not. I'm ok with a meter and insurance.
Yeah, this is me too. I have a similar meter to check on voltage problems and a circuit tester that came with the trailer. I am into this for about $14 total. I certainly understand those who full time and/or have lots of expensive electronic devices with them. But, as others have pointed out, that is not my situation.
I have read this thread and those who specifically stated problems that they encountered only mentioned voltage drops and open grounded systems. I have experienced both, have identified both by using my inexpensive set up.
Just curious how many folks use electrical surge protection for the AS?
Plugged in to pedestal in Medora N.D. had a open ground. Talked to manager and he said they just repaired that one and it should be fine. I asked to plug into site next to me since it was unoccupied, it was fine.
Left for drive around and when we came back they had the pedestal on my site torn apart. They knocked on the door in a little bit and said try your site now. I did and it was fine, they just said ok and never explained what they had done.
Glad I have the surge protector but I really worry about brown outs more.
Kind of a funny story. We've got some guests in the park with a new-to-them used RV. The plug on their cord was pretty burned up, and they didn't clean it up. And they bought one of the devices above and plugged their burned plug into it. One night on the road before they got here, and it had already fried the inside connectors on the device.
Those that answered explaining they operate computers that need "clean" power... I hate to say this but the surge protector will not provide that.
They will only open the circuit and interrupt power should it exceed stated limits. It does not filter or "clean up" noisy power sources.
Further, most computers have power supply's and cords with devices on them that clean up the circuit.
The real advantage of a surge protector is when you're in a park and someone nearby shorts-out and spikes the system, or during a storm when lightning strikes overhead lines. While your electronics that have power supply's built into the cordset will likely be OK, the other items onboard using 120v and your power converters might suffer damage if a good surge protector isn't used.
Another feature of some (like the Progressive I use) is that it keeps the circuit open for two minutes in the event of a power-outage, in order to prevent the AC compressor from burning-out if power flashes off, then immediately back on. (The compressor hasn't had time to unload head pressure and my burn up in attempting to re-start. The Progressive prevents that sort of problem.)
One of the silliest things I've ever noticed was at my friend's workplace. He's a microchip-engineer at Motorola. Virtually ALL the engineers in adjacent cubicles in the engineering section tie overhand knots in all their electronic device power-supply cords. They offer good evidence that will provide meaningful protection in the event of a nearby lightning strike. (Has to do with an induction-loop created by the knot.)
I use a surge protector but have yet to claim it's done anything but make my wallet lighter.
I think that the distinction should be made between a surge protector, which works by sacrificing itself if a large electrical surge occurs, such as you would get from a nearby lightning strike to disconnect your electrical system. In contrast are the EMS devices such as the Progressive which combine a surge protector with monitoring that will prevent connection if it senses any of a number of electrical faults, such as high or low voltage, a ground fault, and some others that escape me now. The nice thing about the EMS is it will show an error code to indicate the detected fault.
Hi, I bought a 30 amp surge protector but seldom ever use it. If I feel that there is a thunderstorm on the way, I will use it. If the storm is already there, I won't go outside and touch the power pole. So it won't get used.
I always have a polarity tester plugged in, in my trailer's kitchen; I also have a Kill-A-Watt that is always plugged in, in my trailer's kitchen. Voltage and polarity is always checked. I made a 30 amp polarity tester that I use at the power post before plugging in my shore power cord.
