Yes that's the one...


So that's just a simple surge protector that will do nothing to protect your rig from any other campground power source anomalies. Do yourself a favour and invest in an EMS w/surge protection, the most popular and most recommended one here on the forums being the EMS-PT30X.

Surge protector means transient high voltage spikes protection (i.e. generally just pure surge protection). Some units also include the basic 3 light household circuit detection. This device does not protect against low voltage, open grounds, etc. that can occur after the initial plugin check.

Note: The term “surge protection” is sometimes used to imply EMS protection devices described below.

A Power Protector or Energy Management System (EMS) is designed to continuously monitor the power and shut down (or never allow initial power) to the rig when a fault is detected including power surges. Faults also include miswired pedestal, pedestal changes like open ground, high/low voltage and high/low frequency.

EMS units are more expensive but they disconnect the power to the RV when required. Low voltage is the most likely cause for a disconnect which will then protect AC motors (especially A/C motors) and other devices.

The Progressive Industries units are excellent and I like the hard-wired unit with a remote which I have mounted inside the RV. Click

Another recommendation for the PI hardwired unit. I like the remote display.

Yup, don't waste time and $$ on that! Spend the extra $$ and get a Progressive Industries EMS that will automatically protect against various electrical issues and is excellent quality. We have the hardwired version - always there, always protecting us (and it has a number of times).

The joule rating of 1050 isn't all that great and they don't tell you what the peak surge current rating is. A PI EMS (the most recommended "EMS") is rated 44,000 amps and 1800 joules.

It's not UL listed either so what's inside is unknown quality. If it's anything like Chinabomb tire quality, it could explode at any time, lol... [emoticon]


I hate CAPTCHA. It just will not go away...

^^this. Not UL (or CSA) rated would be a killer for me.

I've got a Progressive one. It's gone off more than once for low power and probably saved me a big expense.
