Protect your expensive electronics

Last year, the park I stay in had several electrical issues. I know of a fried microwave, 2 fridges, and a inverter fire. This year so far, 2 more fridges and a TV. It's well known that there are big voltage fluctuations here yet people either don't know about electrical protection or ignore it and hope it won't happen to them.

I just ordered an EMS (electrical management system) that protects from too low, too high voltage, reversed polarity, bad ground etc. It shuts down and continues to measure voltage then comes back on if it returns to a safe level. I'm no electrician but it seems that all those that are at risk should protect their expensive electronics with something more than a surge protector.

  • The best insurance is a good quality EMS.

    Sure people can have everything covered under a conventional insurance policy. But what about not having the use of the failed equipment just when you wanted to spend a wonderful time camping. Then there is the inconvenience of getting things repaired or replaced along with the possibility of a long wait for parts or repair service. :R
  • I have seen the problem firsthand - a park took a nearby lightning strike that took out a transformer. Surge followed by blackout, followed by another jolt as power was re-established, and some folks took some damage. I will always use line protection, especially now that I have a brand new rig. A few hundred dollars of protection beats insurance claims and a ruined trip any day..
  • like insurance. car, trailer, etc.

    tens of thousand.. maybe millions of campers... 5 or 10 equipment failures...

    Odds are 99 1/2 percent will never have issues. my opinion.

    just like over pressure in the water supply. few fail.
  • I'm another camper with over 30 years and I had to change the male end of a 30 amp cord, that's it.
    You should move to another park.
  • We must camp is different places than others. 30 years of LOTS of camping all over the country and never had any of these catastrophic electrical problems.

    (I have probably jinked myself and next trip out my entire electrical system and all components will be fried)....:o

    But, yes, a quality EMS is probably a good idea.

    I use a small 1500WATT UPS unit here in my Radio Ops room at my house setup for all of my sensitive computer and radio equipment...

    This unit regenerates the 120VAC to run my items and immediately switches to BATTERY when the input 120VAC doesn't meet the safe mode standards. My setup switches so fast I sometimes don't even know it has happened until the family comes in here asking if I knew the power was off...

    Seems to keep all of my sensitive items pretty well protected... Being small however I don't get do much when running off of the UPS unit internal batteries when in that mode and maybe all I can expect to do is a normal safe shutdown of things...

    Works good for me here in the stick house...

    Most of my camping is OFF-ROAD camping where everything is run off my own 120VAC source being generated by the onboard batteries and Power Inverter... Then i re-charge my battery banks each day using my 2KW Honda generator for three hours each morning. Only stay in the campgounds with electric hookups when moving across my local region here...

    Sounds like most everyone that depends on living at the different various shore power sources all have the expensive surge protectors. I think I would want to have things run off of a larger POWER INVERTER when the Surge Protectors switch you off line.

    Just some of my thoughts here...

  • If I knew of that man problems, I'd find a new park
  • In 15 years of camping I have never had an electrical issue. But if I did, I have insurance. I don't sweat the small stuff and I don't pet the sweating stuff. I have higher priorities than spending $300 on a EMS.
