Surge Guard Install

[arkaussie]

I just updated my Motor Home to a 2016 Journey and purchased a new hard wired Hughes Autoformer to install only to find I have a TRC surge guard 41260 transfer switch which they claim to have "limited RV Protection".


My question is can I install my Hughes Surge Protector to the output line of the current transfer switch or would I be wasting my money and time. I can still return it.

The Hughes Autoformer is typically installed in the shore power path to the transfer switch, not on its output - and before any power gating power protection device.

You don't want the gating power protection device shutting down on low voltage before the Autoformer gets a chance to correct it - would defeat the purpose of the Autoformer.

The 41260 is basically surge protection only.

Install the Hughes on the Shore power line BEFORE the Transfer Switch

Thank you for the answer, makes sense I guess. I was thinking about covering the Genny as well. I will install it on the input cable

Main function of a Hughes Autoformer is to correct low campground power pedistal voltage. So it has to be inline before any power checking device.

A hardwired Hughes Watchdog or similar can be installed after the transfer switch. Although most are installed inline to the campground pedistal, and consider the generator a trusted power source.

I've a portable Hughes Watchdog surge only at the campground power pedistal -> Hughes Autoformer -> hardwired Progressive Industries EMS -> transfer switch.
