Progress Industry 30 Amp Problem?

Following was a recent posting by me responding to another thread related to surge protectors:

During a camping trip at a state park last year, we got no power to the TT when the PI 30 amp was connected. Once the PI 30 amp was removed, however, full power was flowing to the TT. We waited for a while, tried a couple more times and got the same result. It appeared that there was a fault with the power source and that the PI 30 amp was doing its job. So we were facing a dilemma: camping without power or taking a risk and connecting to the pedestal without using the PI, thus defeating the purpose of owning a PI 30 amp. What would you have done?


Well, the same thing happened again at the same state park this week. When I connected my PI 30 Amp unit to the power pedestal, it read 116 V, E0 (which means "normal"). However, when I entered into the TT, there was no power - a separate meter that I had plugged into one of the receptacles in the TT read zero volt and zero amp. But as soon as I removed the PI 30 amp, I immediately got full power.

Can anyone suggest what the problem was?

Btw, I decided to take the risk and connected to the power pedestal directly. We used the ac, fridge, microwave, water heater...for the entire three days when we were there with no issues. Were we just lucky or that my PI 30 amp unit was not working properly?
  • I'd SWAG that you have a faulty PI30. Is there a junction box on the PI setup? I remember someone posting about a similar problem that had a loose neutral wire inside their junction box on a PI product. IIRC, it was replaced by PI, under warranty.
  • Or I would suggest you surge potector was doing its job but yet you still plugged in directly with no surge potector....lucky
  • Did you wait the two minute delay?

    If yes, then I would contact PI. They have very good customer service.
  • S.K.--- Could this be the issue?

    There is a delay built into the Progressive Industries device. It sounds like your device is portable, that is not hard-wired; those devices have a 2:16 delay built in. That is, from the time you plug in the device until power is passed through it (assuming no power problems) there is a 2:16 delay - this is to protect the AC compressor when power cycles off then on. Maybe the delay is why the power did not flow to your trailer?
  • For a couple of bucks buy one of these so you KNOW what is going on at the pedestal. I don't plug anything in until I check the pedestal first with this tester. Can't tell you how many I found to have an open ground.

    I bought one of those at walmart. the white and faint yellow markings on the label were virtually illegible. I returned it and went to Lowes and bought one that had a black background and yellow markings. much better.

  • Thanks, everyone! I have totally forgotten about the 2:16 delay thing.

    Most of the time, after plugging in the PI30 and connecting the power cable, I would go about doing other set up chores before entering the TT to turn on the A/C or other appliances. That takes a lot longer than 2 minutes. For the couple occasions that I described above, I think I probably had entered the TT right away after plugging in the PI30 (yes, it is a portable one) and cable trying to turn on something and found out that there's no power. Hopefully, that's what it was. I will definitely check this out the next time when I am out there camping.

    I might also get one of these polarity testers. It appears to be a very handy item to have around as an additional insurance thing or for checking against the PI30.

  • Just a quick update. Went out to the same state park the past week and proved that it was indeed the 2 minute delay at work - got E0 but zero ampere right after plugging in, then full power after waiting for a few minutes.

    Thanks much for the help, I love this forum!
