Q for Mansfield Attendees

Did anyone experience electrical power problems at GMCMI Mansfield? I ask
because we were never able to operate our Dometic 2652 refrigerator on 120
vac while there -- the circuit breaker would trip periodically. The first
time it happened, the automatic transfer to LPG allowed the tank to be
emptied and the refrigerator to defrost. After several tripping incidents,
I got the tank refilled and ran from it until we got home.

Here, I tore into the refer expecting to find a flaw -- everything checked
out fine. And it's run on 120 vac without problem ever since. So, I can
only suspect voltage spikes, or something at Mansfield, the ONLY place the
refer has ever given trouble during the 9 years it's been installed.

Ken,

We had no issues and we run a 120V reefer.

Ken:

I was in the 30 amp outlet, and tend to use a bit of power when on mains.

No problem with the Danfoss fridge, Heat Pump or resistance heat.

The Xantrex also identifies flipped neutrals and lifted grounds (it gets NOISY with the latter), and shows voltage and frequency.

All was good.

Hi Ken:
Mike Kelley here.
We had no problem at Mansfield - ran refridge and A C on a 30 amp site.
Sorry you had a problem!

Ken,
The only issue I had was one cold morning...
-Electric water heater ON (1000 Watts)
-Electric space heater ON (1500 watts)
-Coffee maker ON (~1000 watts)
-Electric Fridge (random operation.. 600 watt start, 90 watts run)

Plus various other small items

Well no surprise, we tripped the 30Amp breaker. Then voted that a warm shower and hot coffee beats warm feet!

I have logging on my Inverter/charger. I've never looked at it but it would be interesting to see. We were in row F.

We ran our refer on AC the whole time while there and had no issues. But we
didn’t run close to the edge—didn’t need AC after the first day and those
toes were heated with propane. We did run the microwave from time to time
and all that “red” hair gets dried with a 2000-watt hair dryer, but I don’t
think we ever even turned on the water heater.

I wonder if the breaker at your site was starting to get flaky.

Pretty sure we shared the same post, Ken (we were parked directly behind you). Ran our refer, space heater, water heater, and coffee maker without
any problems. Polarity meter never waivered, either.

Thanks to Everyone for your Mansfield power reports. I guess I'm not
allowed to blame their supply for my failures. :-( I'll keep looking &
report if I find the problem.

Fred,

Good general advice, but apparently not applicable in this case. Even
those plugged into the same power pedestal as we were report no
electrical anomalies at Mansfield. I have to assume the problem is in our
coach & will continue troubleshooting. But it's hard to find a problem
that no longer manifests itself. :-)

Ken, just because you were on the same pedestal don't assume you both were receiving the same juice. Your receptacle or breaker would be unique to
your coach even if the main or buss are common to the panel. It may indeed be a park issue, or not.

This opens another question - how many use “Power Defender” pigtails (basically some MOV’s and some circuit to identify flipped hot and grounding problems)?

I did before I installed the Xantrex (which does most of it, and has smaller MOV’s internally installed on the input side).

Oh… MOV’s “Metal Oxide Varistors”, basically the operating part of the surge suppressor you likely have on the AC input to your desktop computer.

Basically, when it’s voltage is exceeded, it “clamps” and forces the circuit breaker ahead of it in the circuit to trip.

Ken, when we arrived Cat plugged up our electrics while I did the water. I didn't notice till we got ready to leave that She left the 50-30 amp
adapter and the 30-20 adapter in place from where we were plugged in at home before we left. No issues tho.

Sure, I carry one with me all the time -- helps keep the storage
compartment full. Can't remember the last time I plugged it in. Sure hope
it's helping protect the coach wiring.

Fact is, I've been fantastically lucky for the past 65 years of RVing, from
Key West to Fairbanks -- NEVER had a significant power problem. The worst
I've ever encountered is a lot of over-sensitive GFCI's. NOW everything
will get blown out/burned up!

Too bad, Chuck. I finally quit using water pressure regulators after it
got too expensive replacing the ones I left behind. :-(

Hal,

That's true, but the chances of it being a campground problem are certainly
reduced significantly by everyone else's good experiences. Since that
breaker HAS popped on occasion (when activating the 1-1/2 hp compressor
that shares it), I'm assuming it's MY problem.

Water pressure regulator can replace the original so you need not worry
about leaving it.
We have them in stock, one of our top seller.

Using a couple of channel lock pliers, I attached mine semipermanently to the hose. Haven't left one behind since. Actually have picked up several
that others have left behind....maybe yours? :roll:
