You can not have it both ways. You either go with the power booster and hope you don't get a spike to kill it, then have the PI unit to protect the RV. Or you go with the PI which will shut down you RV power if there is a power condition problem. And if you have the booster after the PI, it will not do you any good because the PI will drop you out if the voltage is low before the booster and push-it back up. I have the PI only and it is installed after my transfer swith. JMHO Gary


No So, another member found this for me and posted it in IRV2

Using the Surge Guard Voltage Regulator in conjunction with a Surge Guard® RV power protection product provides the ultimate combination of low voltage and Surge Guard protection. The Surge Guard must be plugged in after or down stream of the Surge Guard Voltage Regulator. A variety of Surge Guard products protect your RV from: High/LowVoltage, Open Neutral, Miswired Pedestals, and Surges

The voltage regulator is not a real surge guard (it is a spike guard/supressor) this is an industry accepted mis-label however so no fraud there.

IT comes first.

Then the real surge guard (Which by the way ALSO includes spike supression, but in addition it is a surge guard, IF a real surge comes along (Sustained high voltage) the voltage regulator it going to sound like July-4 Fireworks as it's MOV's blow, but the Real Power line monitor/surge guard will simply cut you off to protect you)

That simple. That way if a low voltage hits the regulator will boost it before the power line guard type cuts you off.

on that rolled up cord

Unroll ALL OF IT before plugging in, do not coil power cords when in use.

Got a question about Surge Protectors, asked this question in another forum but got no replies. I have 50 amp service and looking at getting the EMS-HW50C. Sometimes I plug into 30 amps when 50 is not available. Will the EMS-HW50C still function as normal, I know in theory it probably should, but has anyone actually did it.

Yes, the FAQ on the website confirms 50a will work fine on 50 or 30.

All you need is the dogbone 50 to 30 amp connector and it will work fine. I have been doing that for years at shooting ranges I camp at which are always 30 amp and underpowered for the number of campers at the match. Numerous times my Surgegard has shut the MH down in the afternoons when A/C draw overwhelms the ranges electrial capacity.

I will have a Hughes Autoformer voltage regulator this year because a number of my buddies use them and survive the low voltage hours without being shut down and they always go before the SurgeGuard.

I had a Franks Voltage Booster for 5 years and always used it. Last year at the Thousand Trails in Acton Calif. they had a Transformer blow up and it Tossed my Franks Booster. I called Frank and they will send me the 2 circiut boards that went for only 400.00.if I want to install it myself but I don't know if anything else is wrong with it, so it is now a big paper weight.Yes they will not survive a spike if too big, 600.00 down the drain.

Do you have RV insurance should cover damage due to this type of failure.

Tend to get confused on upstream vs. downstream. I have surge guard and regulator, memory tells me that a regulator rep told me regulator first then surge guard. My thought is post is upstream (plug in regulator), coach is downstream (plug in surge guard)? For all those w/the same question.

Have to admit that it seemed logical to have surge guard plugged into post to protect regulator but that doesn't seem to be the case. HELP

LOL That is what started this Thread.

You are Correct, power flow through regulator first then through surge protector, then Coach.
