Shore power - 50 amp to dogbone splitter to 110 amp
« on: March 29, 2021, 05:35:45 pm »
Quick question: I'm a new 2021 Model 2552 owner and I can't seem to get anything to work with shore power connected to my house with a dogbone splitter to household 110 amps.  What will the 110 power up in the Phoenix assuming it actually connects.  So far I haven't been able to determine if it is actually supplying any power to the RV.  Thanks.

Hmm, It sounds like something is switched off.  There is a switch by the entry door to turn on 12V to the entire interior.  Try that.  Also make sure every 110V breaker is turned on.  The indicator that you have 110V operating is the clock on your microwave oven.

Agree with Ron, the microwave display will generally be a good indicator of shore power.
And be sure all 'switches' are on.  2o2

If your supply is only 15 amp and from a garage outlet, you may have popped the GFI or breaker in the garage.

Thanks for the replies.  Right now I'm hooked up to 50 amp so not a problem.  I'm not aware of a 12V switch by the entry door on the 2552.  I will investigate.  Another question is when to actually have the inverter turned on.  Only on battery power or just leave it on all the time? Thanks.

With the reference to the "switch by the entry door to turn on 12 volts", Ron was referring to the main house battery disconnect switch located on the end of the cabinets immediately to your left when you open the coach entry door.  If the 2021 models are identical to earlier units (and I'm sure they are), on the cabinet end there are some (3) rocker switches and one large rotating switch that rotates 90 degrees.  That rotating switch is the main disconnect for the house batteries, and when rotated clockwise it connects the batteries to the coach electrical system; when rotated counter-clockwise it disconnects the house batteries from the coach.

Regarding your question about the inverter.  As I'm sure you know, the inverter has one purpose--to provide 110 Volt AC electricity to some of your equipment and some of your outlets when you have no other source for AC voltage.  When you are hooked to external power, or are running your generator, those provide AC power to the coach.  When neither external power or the generator is used, you can power some of your AC needs from your house batteries by turning on the inverter.  That converts the 12 volts DC from the house battery system to 110 volts AC and supplies it to some of your circuits.  There is really no need to leave your inverter switched on unless you are using it to power your coach.  I think the best practice is to leave it switched off when using external or generator power, and only turn it on when you actually need it to supply AC voltage--when you are underway on the road, or parked without external hookup or generator.

The inverter is of no use if you are plugged into shore power. It is to convert 12v to 110v when not connected  to shore power.  It uses power even when not needed, so not a good idea to leave it on.
I'm curious as to your source of 50 amp at your house. Did you have a 50 amp outlet installed for your RV, or are you using a clothes dryer outlet? Very few homes have a 50 amp in the garage, unless it is 220v, in my experience.

Good catch regarding the 50 amp at home.  I don't park my rig at home.  Protective covenants won't allow it.  I am fortunate to have a spot at my brother-in-law's commercial building where he had 50amp service installed for a previous RV he had.

We'll, several things you need to do.

Is the 50a outlet at your brother-in-law's commercial building turned on?  As in the circuit breaker to it ON?  Are you handy with a voltage meter?  If so, test the voltage between the bottom slot (neutral) and either side slot (hot) which should read 120v.  Test both side slots, one at a time.

No power on either one or both?  Have your BIL get an electrician to fix.
If they BOTH show power, move on to the next step.

Now, plug in the 50a to 30a dogbone.   There will be 2 angled slots and one uo/down slot.  Test the voltage between the two angled slots, it should be 120v.  If not, get a new dogbone.  If so go to next step.

Plug your shore power cable into your PC's power socket and plug into dogbone.  Are you getting any power in the RV at the 120v outlets?  Is the microwave display on?  If not, check your power panel, flip all breakers OFF.  Then, starting with the breaker labeled Main, flip them On.

If that still doesn't give you power to the outlets... You have a wiring problem, call your dealer and have them fix it under warranty.

Thanks to all for replies.  50 amp power at the commercial building is working as it should and is not a concern.  I'm just wondering if my fancy $70 dog bone could be the problem when attempting to go from 50A to 110 at my house.  It says on the 110 side of the dogbone that it won't work with a GFCI outlet.  I will still experiment with other outlets the next time I bring the rig home.

Not sure what you bought for $70, but something like this at $17 is what you need.

Your question if to leave your inverter powered on all the time may be confusing to some. The inverter has a internal transfer switch. If you have 120 volts supplied to your coach the inverter will allow the power to simply pass through to power the 4 outlets and possibly the microwave depending on how it was wired. If 120 volts is not supplied you can simply turn on the inverter at the switch located by the generator control. This will shift the transfer switch and convert 12 volts from the battery to 120 volts powering the 4 outlets (tv, outside, bathroom and kitchen sink).
So my point is there are 2ea 120 volt circuit breakers in your power panel. Power into the inverter and out of the inverter. These breakers need to be on to power the 120 volt outlets. If you are not connected to shore power and want those outlets powered, your house battery (12 volts) supplies the inverter which makes 120 volts for the 4 outlets. The inverter is turned on like I said above at the panel by the generator control.
  My 2552 had the Xantrex 1800 watt modified sign wave but I changed it to a Magnum 2000 watt pure sign wave so I can run the microwave.
Not sure if this helps but this setup can get somewhat confusing.
Good luck and welcome to the Phoenix Cruiser Family.

The 2ea 120 volt circuit breakers should be on all the time. There is no reason to turn them off.

If the 3-prong 110 volt type extension cord you are using at home works with some other 110 electrical item on that outlet, then it has to be the pricey dogbone adapter or the GFI. The GFI may be in some other location on the same circuit or in the breaker panel.

I'd sure like to see a picture or a web link of the what you called a splitter, but I assume it is an adapter.

Out microwave isn't on an inverter outlet. Did you rewire?

Our microwave isn't on the inverter either.  Somehow this conversation has taken a different turn. lol  The question I had was that the 110 portion of the dogbone wasn't working and I wasn't sure why.  It's not a big deal but the dogbone was expensive and I felt like it should work.
