I prefer the hard wired one,less to remember and I like the remote I always use This to check the pedestal before I back in and I am ready to go.

I use this before plugging in.

My 2004 hardwired unit is in the second rig. In each case it's installed without cutting/splicing any existing wiring so trivia to remove and restore original wiring. It also has a remote display inside the rig which is a HUGE advantage over a portable. Voltage, amps, error codes are all easy to see. A data wire has to be routed to the remote.


Ya gotta plug it in, don't you? You can easily see the portable unit's display as well, when you're outside the coach doing that. If it reacts to something and cuts power, you're not likely going to be able to either trouble shoot or resolve it from the comfort of the inside of your coach, you're most likely going to have to exit the vehicle at some point to resolve the problem, so it's really not a huge advantage. Very few shore power issues occur inside your coach.
The problems are rarely apparent when you plug in and almost always occur UNDER LOAD. Especially true on 30A pedestals.

Just can't beat seeing issues like low voltage from inside. Or when I return on a hot day and go inside I can check for low voltage with the Prior Error code - RED FLAG start observing and/or take corrective action. Not likely to stop by the pedestal first to see (if possible in the sun) what is going on.

2 months after the 2004 install and 10:00 PM power was shut down and the PI unit showed 160V on a 30A pedestal. Fliped off the rig CB, got dressed and pulled the power plug.

BTW with 15 years of use there were only 2 times when the PI unit would not initially connect. Both times is was reverse polarity on a 30A pedestal.

So I'll take the hardwired unit and inside display any day. But to each his own.

We are fulltime and I hard wired the unit. We stay weeks or months at one location. Personally, being a weekender etc. that is just one more thing to hook up and unhook. If like me I could get lazy some weekend, and say, "ah, been here before, was OK so baloney on putting it in line". Just find the entrance cable, cut it at a convenient location, and install, always there, good to go. Trading rigs, undo what you had done, splice cable back together.

Just a weekender mostly. Last thing I want is one more chore to remember and execute.
Mine is hardwired. Could easily swap to the next RV but I would probably just get a new one as it might be a 50 amp next time.

I'm not really sure I understand this "One more thing to remember to do". My portable EMS is always plugged into my electric cord, and the EMS is what is plugged into the pedestal. Last time I checked you had to plug into the pedestal to get power to the RV.

In order to use a hardwired EMS, I'd have to do some fancy rigging, plus it would not be easily accessible if I needed to have it repaired/replaced.

OTOH my old SurgeGuard bit the dust after suffering water intrusion. The PI I have now looks to be much more watertight than the SurgeGuard.

I have never heard of anyone having their EMS stolen, not even any rumors or hearsay.

So my cord pulls nicely from the mouse hole. EMS not going to fit. Need a place to store in transit and need to pull it out etc.

How about "both" sort of....

Now due to a very attractive sale at Camping world I just "installed" a Surge Guard by TRC (The company name on the box is different but it's TRC)

I used to have an older portable I got for shipping plus repair (needed new 50 amp outlet)

I stripped the plug and outlet off the old failed portable and transfered them to the new HW unit. Protected the terminals (They are exposed. I do not like exposed terminals so I protected them multiple layers of protection) and "Installed" it between my Hughes Autoforme (already"installed") and my Auto Transfer Switch.

The Install is same as the Autoformer so google the Hughes install kit.. Which I home made.

Works (So far) very well

NOTE

Park--Hughes--TRC Surge guard--Transfer

That way if the park is a tad anemic (next week has that issue) the hughes makes up for it so the Surge Guard passes power.

So far it's shut me down once. (Power in that park can be very anemic).

Fun 2 weeks. IN addition to doctor's appointments (2 different docs)
New cooling unit in fridge
New floor in slide out
Got rid of 15 year old cat-shredded couch
Serviced Front A/C (Read did not need it) Thanfuly a Coleman (Easier to service)
Mopped roof
Washed entire outside
Waxed Entire outside with "Ceramic Wax" (Easier than the other kind we will see how it works).

Tomorrow I change campgrounds

Tired am I.


Home is where I park it.

That do make a difference for sure. For cords that have to be plugged in at both ends, not so much.
