Surplus Electronics stores sometimes have them. I bought 120 units pallet of them in Rohnert Park California 43 years ago. They were military USAF unmarked 460 watt multitap. -30 20 10 0 + 10 20 30 for $440 Full 50db isolation.
You may have to drive to a big city or to near a USA USMC or USAF base. Mew ones as you know are expensive.

I took my camper to my daughters house. Son in law said he wired in a 30 amp breaker. I asked if it was 120, he said yes. I plugged in, and no joy and progressive EMS wouldn't start up THANKFULLY. He had bought a double breaker (240) and wired that in. Once I fixed it, everything worked fine.
No doubt without the EMS, I would have fried a bunch of stuff in RV.

I never plug in without checking voltage under load.
30 amp to 15 amp to octopus divider to kill-a-watt and to load (1500 watt heater on high)
I also have a breakout box for use with a 50 amp service.

Lol. Sounds like someone who shouldn’t be playing with screwdrivers in a breaker panel…

Even though I have a PI EMS-HW30C, I never, ever, plug in my RV until after I plug in this:

That is a good idea but alas the voltage reading you get will be "no-load" and under load it can drop like a rock in free fall.. after you plug in move the volt meter to an outlet INSIDE the RV.
Home was where I park it. but alas the.

If the ped gets hit by lighting no protector is gonna protect it right???
Well when you consider the chances of the pedestal being hit by lighting, to the chances of low voltage or missed wired pedestal our PI 50 amp hardwired EMS, the $70 is poorly spent! The PI hardwired unit has a remote display which displays current amp being drawn and current voltage. Even at $400 cheap insurance! I just looked on the interweb and saw prices from $267 to $427, on Amazon I saw it for $333.

That is very true. However, nothing is perfect. If you pull in and test the line voltage "under load" and it is fine, the next day when everyone turns on their air conditioners at the same time, the line voltage could STILL drop like a rock. After all, you are not watching the voltage meter ALL THE TIME. That is why I also have the PI EMS-HW30C. (And, if I suspect that low line voltage will be a problem, I plug in my autoformer.)

Bobbo,
