Got my PI PT30C today! YES, I READ THE BOOK! Plugged it in to my 30amp plug in my trailer building, an E1 displayed. Says I have reverse polarity in the plug and would not let the power go through. Called an electrician buddy of mine an he directed me to switch the black and white wires. Hooked everything back up. It showed no errors and after 2:16 I heard a snap from the box and wahlah I have power!
A lot of people balk at the price, about $380 for the 50 amp one, but low power at campgrounds can be a big problem also and the damage does not show right away.
Just ordered the 30 amp Progressive Ind. surge protector on sale at camping world. Added a 25ft sewer support and got the $50.00 coupon discount and free shipping with my Good Sam membership. Both items after tax were $216.00. It was like getting the sewer support for free and a great price on the surge protector.
We have the 30 amp in line surge protector. It has tripped twice. Both times during an electrical storm. The cost of the protector is a lot less the replacing one board in the trailer. Will not leave home with out it.

I have a progressive 30a hard wired. The power was so low at one site that it kept kicking out. The power was below 104v. Thats hard on the A/C! The surge guard did its job!
Just purchased a TRC 30 amp surge guard for our TT. We had issues with our power supply at our family cottage and we had to reboot the frig a few times. Hopefully this will solve this issue. So far, so good.

I brought the TRC 50 amp SP at CW shortly after I started reading about them here. It is heavy, but I am glad we have it.
I found this PT-30-C on Craig's list thirty miles from my home. The seller told me he recently had to sell his new TT and had only used this unit once. He also mentioned that his first TT got zapped one night several years ago and fried his microwave, television and blew all his fuses. He spent $500 repairing and replacing damaged items. He promised himself it would never happen to him again, so he purchased the PT-30-C when he bought his new TT. He had a 30 amp outlet in his carport so I was able to see the unit work before paying for it. I gave $75 for it today complete with original receipt and owners manual. One less thing to worry about!

Besides my surge protector, I have a TRC Digital Line Monitor showing current voltage incoming to the trailer with high/low alarms from Campingworld. Haven't seen anything below 118 volts so far at the Corp Of Engineer campground around our area lakes. This weekend will be a test as everyone will have things cranking with temps around 100.

What are the benefits between hard wired vs portable other than being able to use the portable on other trailers, etc? Seems the hard wired protectors are a little cheaper. I would also think hard wired is maybe a little more beneficial when going from 50a to 30a only because you aren't plugging the 50a into the surge protector then that into the 50/30 converter and that into the pedestal.

Do you need both? My TRC 50 amp SP shows that info on its digital display.
Cheap security for your surge protector is very simple.
1 four foot piece of chain, one "S" hook, 1 master lock.
Put the "S" hook through the last link, use vise grips or vise to close "s" hook on last link. Now place the "s" hook and chain around bottom the surge protector cable just above the female plug, bend the other end of the "S" hook close to complete the security of your surge protector.
Four feet of chain will reach around most electrical pedestal or post in any camp ground.
I know the chain can be cut, but it will make most thieves move on to the next unprotected surge protector.
I took a page from your book and went to Lowe's and picked up this 1/2"cable and lock for $10 to wrap around the pedestal. I figure it can't hurt.
