Questions on Hughes Autoformers AC Digital Voltmeter & Surge Protector


I thought I had seen on your site 2 versions of this meter a 50 amp and a 30 amp capacity. I want to check the pedestal at campgrounds, some of which have 30 amp system and some have 50. I am looking for a 30 amp meter. Is this it? Thanks


Expert Reply:

The Hughes Autoformers AC Digital Voltmeter, # HU28FR that you linked to is for measuring voltage at an operating range between 108 to 132 volts. This is irrelevant of the amperage supply from the pedestal.

If I understand correctly that you are wanting to monitor amps being supplied to your RV, I suggest a surge protector. From Hughes, we have the Power Watchdog Surge Protector, # HU97FR for 30 amp and # HU47FR for 50 amp. The 30-Amp or 50-Amp surge protector offers 6,100 joules of protection in case of lightning strike or other events and prevents damage to your RV from these power spikes. The Power Watchdog surge protector is plugged in before connecting your RV to the power pedestal. This then provides a clear indication of any wiring issues at your parks power pedestal.

There is a free Smartphone app for iOS and Android that connects via Bluetooth so you can monitor your systems volts, amps, and watts in real time. You can even set it up to provide push notification when voltage is outside of acceptable range.

Please note the linked product review videos below. Whatever brand or model you purchase, I highly suggest investing in a quality surge protector of some type.
