Surge Protector Reading L1

Here's a bunch of folks in a campground that should have been performing their regular multimeter tests like diabetics checking their blood sugar levels!..:R..:R

"The electrician said Oops"

(Multimeter) timing -IS- ......everything, LOL!

And ......YOUR *everything* zapped - - when *your* timing is a bit off..:(

At one campground I kept getting low voltages on my PI EMS. Campground was sure the problem was the EMS. Called PI and they gave me an easy test to detgermine if the EMS was working properly. Started the generator and when the coach was on Gen power, ran an extention cord from a coach receptacle and plugged the SP cable into the extension cord via a 50-30 pigtail to a 30-20 plug. Low and belod the EMS was dead on - 120VAC @ 60hz. I now run this test to verify if the generator is working correctly. Most of use don't carry a freqmeter - the EMS has a built in frequency detector. By the way, we left that campground in RI never to return. JM2¢...

That won't help with the OPs issue since he already knows he has high voltage where he is and can monitor the same at any where else he plugs into.

He thinks he has an issue. Yes, his Surge Guard protected him, but now is the Surge Guard still doing its job or has it failed and is giving erroneous readings? The only way he will know is to unplug and check the pedestal. And checking the voltage is not a one time thing. You should check every time you plug into a pedestal.

A multimeter does not replace a Surge Guard or some other line protection device, its just a very useful tool that could keep you out of trouble before it bites you.

A multimeter is also useful for other things that go wrong on your rig. Anytime I have an electrical issue, the first thing I do is check the source and work my way out.

Why get a multimeter for a one time check when he already has a surge protector performing continuous checks? Just because power is acceptable before you plug in doesn't mean it will stay that way.

Well plug into a 220 improperly wired receptacle and you will wish you had checked. True it does not mean it will stay that way either but you are protecting your rig first of all. Second you can tell what is hapoening on a pole. A fellow camper came over and said only one of his ac units was running. Looked at his system he only had power on one leg. Multimeter showed other leg was 90 volts so his system was protecting the coach but we moved him to another pole and all was fine.

My EMS will tell me what is happening on each leg independently and will NOT allow the "bad" power into the coach...that's what it's for! Like the other post said...things can change after you've checked with a multimeter and you would NOT know...with an EMS you will!!

It rained for several hours and couple hours after it quite raining the power corrected it self and went back to 115 volts. This is the second time this surge protector saved me, the other the box had a pig tail to plug into and it was wired backwards with a hot leaded run to the ground lead. They pulled the plug apart in front of me and rewired the plug. Guess it has been a good investment and it's less than 6 months old.

I second getting a multimeter. I check before I plug in too. Not a one time deal. In fact this check takes longer then plugging in. It works and will tell you what the power at the pole is too and verify the surge guard is working.

Had that happen at a park in MD...several coaches lost electronics and one had it's inside breaker box catch on fire. Of course the park swore it wasn't their electric and blamed those of us with EMS for stirring up trouble...many of us pulled up stakes and moved on!

Be very glad your EMS is doing it's job!!

Your surge protector is doing its job...don't ever plug in without a surge protector
