110 house current hookup
I am hooked up to 50 amp service at my home. Going to the sons house for two to three nights.
He only has a 110 receptical at the front of his garage.
Is there a safe adapter so I can use my 50 amp service cord plugged into his 110 receptical?
It will be cold (35 degrees) so I will use propane for hot water and for the furnace. But I need electric for lights and furnace fan.
I can’t run the generator because of HOA police and neighbors

Sure: get yourself a 20 to 50 adapter. It'll plug in at his house, and your power cable will plug into it!

your lights and furnace fan run off of 12v, you won't need 120v electrical for those...

Sure can, with an adapter like this. Of course, you'll only be getting 15 or 20 amps to the RV, but it's better than nothing.

But it might not work. If your 15 or 20A outlet is on a circuit with GFCI protection that safety feature may trip when you plug in. It happens sometimes when there are redundant GFCIs on the same circuit and your coach will have one or more such circuits. If it happens try tripping your coach GFIs with their “test” buttons. Likely one will be in each bathroom and maybe another outside. Otherwise, you’ll be fine.

It'd be handy; if those batteries were kept charged...

If your battery lasted more than one night without being plugged in I'd be amazed.

If you have a residential fridge, you may need power for that also. Even so, 15A or 20A should be enough.

Your converter will only draw 5 amps @ 120 volts so all is good to use all the 12 volt stuff. Try to avoid using any heavy draw 120 volt devices like portable electric heater, head strip on A/C or electric on water heater. The brass pins on a 15/20 amp plug will overheat in most adapters when the current draw gets above 12 amps. Do not use any of the round puck adapters if you can avoid it, as the tend to overheat even in low current draws.

We wind up with 15/20 amp several times per year. To make it work for us the batteries must be charged as the Magnum will kick out over 100 amps and with the fridge and inverter that can trip a 15 amp. Starting with charged batteries we never have any issues at all and luckily mine don't trip the GFCI either.
During the cooler months all we need it heat and the Aquahot handles that well along with the hot water. We don't use the 120v element in the Aquahot however.

I can tell you that the tripping of the GFCI is very unit specific. I have had 6 different 50a rigs, 4 of them, including my current rig, will trip a 15-20 amp GFCI when plugged in. The other 2 would not. Same manuf. of all 6. I am pretty sure it has to do with plugging a GFCI into another GFCI.
I know you can not wire different GFCI outlets in series but you can in parallel. You can not wire a GFCI outlet into a circuit protected by a GFCI breaker.
I don't get put into this situation enough that it bothers me.

I don't have 50A at my house I plug into 15A all the time. Just do not run the AC, it will trip, it keeps the batteries charged and fridge running not problem

At least the a/c units won't be needed at this time of the year...

Thank you I had the understanding the furnace ran off 110volt when MH was plugged into home electric.
Guess I just need to be plugged in to keep batteries charged for two or these days while at sons house.

The "dog bone" adapter works great while plugged into a home outlet.

I recently posted the same question. A safe $30 space heater with the thermostat control has been good for us. Propane ain’t cheap!

We’ve used a 50a to 20a dogbone adapter (like shown above) for several years with no issues. Just be sure the circuit from the house isn’t being used for other plug in appliances. We’re even able to use 1 a/c unit during the summer - just have to shut it off to run the microwave.

I use this for mine and run it on a Honda generator when dry camping also. 1 gallon of fuel for all day running vs whatever the onboard takes as long as I'm not running the AC the Honda is great.

May want to consider changing the house 15 amp receptacle to an 18 amp receptacle. Internal plug configuration is same, One slot looks like a T. terminals in receptacle are heavier and will not heat up as fast.

no such thing as an 18 amp receptacle.  it is a 20 amp receptacle. 15, 20. 30.
