Thoughts on the 'need' factor of a main line surge protector

Progressive Industries surge protectors provide the greatest protection for your RV. A side by side comparison of various Surge Protectors from different companies will reveal the greater protection by P I surge protectors. Always plug your surge protector into your electric source BEFORE you connect to your RV.

I bought one purely for the real potential (get it?) of there being an open neutral when plugging in to 50A.
I didn't bother with one for our old 30A rig but I did install surge protectors on the individual appliances in the trailer.
In either case, I always unplug if there's a lightening storm since no surge protector is going to protect you from a nearby or direct hit.

Simply put: you must have one

I don’t plug in much due to my style of camping...but when I do you bet my TT is protected.

My practice is to insure where it’s required by law or for items I cannot afford to replace. Nothing inside the RV meets that for us. I’ve never owned one, nor suffered any damage in four decades of RVing.

We all have a fire extinguisher in our campers and hope we never have to put it to the test. But if we need it it's there. Same thing with a EMS. If you consider what it will cost to replace all the onboard electronics: AC, furnace board, tv, fridge, water heater, etc, an EMS is low cost insurance.

If you choose not to get one and are unlucky enough to need it, I guarantee that you will get one after you replace your television(s), microwave, stereo, water heater element, refrigerator element, well, the list goes on.

Your choice.

(A lot of folks don't realize that even with a 50 amp setup, you can get 240v through every 120v appliance that is drawing power if the NEUTRAL wire in the power cord or pedestal ever breaks.)

BTW My HW50C purchased in 2004 protected me the very first trip with 160V on a 30A pedestal, not common but it happened and I could not get unplugged fast enough. Its now in the second rig and both DYI installations were done w/o any wires cut and hence easy to move again. But many can't or shouldn't install it themselves which makes the portable unit attractive pricewise.

EMS (Energy Management Systems) units like the PI HW50C protect against miswired pedestals, high/low voltage, surges (power line transients) and other proglems. CGs are notorious for power problems ESPECIALLY low voltage which can damage A/Cs and other equipment including electronics. Don't confuse EMS units with cheaper pure surge units (electrical transients).

30A pedestals often will have low voltage especially in the summer with A/Cs running. Without protection you might not know the A/Cs are running at say 95V. Standard AC is 120V.

I've encountered 5 cases of miswired pedestals, numerous cases of low voltage (mostly 30A pedestals) and 2 cases of high voltage, one was 160V on a 30A pedestal.

On a 50A pedestal a very bad problem is an open or partially open neutral which will cause very high and very low voltage on the 2 hot lines. 50A service is actually 120/240V the same as your home but I'll skip that detail.

PI has a portable unit that you can plug into the pedestal. I much prefer the HW50C (about $350) with it's remote unit that lets me know inside the RV of any power problems.

Some prefer a autoformer which will boost low voltage (about $600).
