Your shore power cord plugs into the side of the unit and the unit's pigtail plugs into the pedestal.
Before I moved it inside (still using the plug system so I can remove it if I ever needed to move it to my next camper) I used to chain it under the slide out and used my 25 foot extension cord to go to the pole. It is water resistant but not waterproof.
It should have NO effect on warranty since your camper is not modified in any way and only pure filtered and surge protected power is allowed inside.
15K AIR startup current = 28.5 amps at 120 volts or 3,420 watts
15K AIR running current - 14.5 amps at 120 volts or 1,740 watts
Suburban Water Heater AC current = 1000 Watts at 120 volts or 8.5 amps
So if the incoming voltage drops to 105 volts, the inductive draw changes
At 105 VAC input voltage (no Franks unit)
15K AIR startup power = 3,420 watts @ 105 volts is 32.5 amps
15K AIR running power - 1740 watts @ 105 volts is 16.6 amps
Suburban Water Heater AC power = 1000 Watts at 105 volts is 9.5 amps
To boost 105 volts to 123 volts (from sheet) is a boost of 18 volts with a 300 watt load. The higher the load and the lower the voltage the more amps are required to do the boost. As you can see when boosting voltage to protect your inductive and restive loads in your camper, careful monitoring of your usage is required even with 50 amp circuit protection if the power is as bad as mine was in Gettysburg last summer when it was 105 degrees outside. The 30 amp run to our campsite was aluminum wire and we were not getting 100 volts on the pole.
Without our Franks, the air would not run at all, even with the fridge and water heater on propane. It saved our vacation. Even WITH the Franks there was one day when the pole power dropped to sub 100 volts we lost power completely when the Franks killed power to the camper to protect it.
