Dishwasher prep

[George]

The receptacle under the island drawers is my dishwasher prep. I see a circuit breaker labeled “DISHWASHER” which leads me to believe that the receptacle is a dedicated 15 Amp circuit for the dishwasher. But I also see that there are TWO Romex cables in the dishwasher Speedwire receptacle. Where does the 2nd Romex go? It disappears through the floor under the sink side of the island. I have tested all the receptacles that I can think of and all are still hot after turning off the DW circuit breaker.
I have contacted Alliance and at first was told it goes to the fireplace and the circuit is intended to be used by either the DW or FP, one at a time. 😮 This is not the case as I have a separate circuit breaker that successfully covers the fireplace. Then I was told that the DW prep is in fact an isolated circuit and to test all 110v outlets. 🤷🏼‍♂️ Awaiting response from me saying that has been done.
If anyone can help it would be greatly appreciated as knowing what circuit breakers control what is a pretty important piece of information. Or if you could peek under your the island drawers and let me know if you have two Romex cables in the DW receptacle.
I have posted on here before that I added an outlet on the outside of the island from the DW prep. I revisited my installation to remove the Speedwire receptacle in favor of wire nuts in a grounded metal Handy box. That's when noticed the 2nd Romex.

George I have a 2022 Paradigm unit the dishwasher circuit was supposed to be shared with the fireplace circuit as Alliance described.
However upon further review I found the circuit was shared with the outlets on either side of the sofa via the transfer box/circuit located in the island cabinet.
In the end it all worked out for me as I wanted to use the DW circuit for a space heater. I did not want to put a space heater and fireplace on the same circuit.
Now I have the space heater on the DW circuit that is shared with the sofa outlets via the transfer box.
The fireplace is on its own dedicated factory circuit.

Thanks for reporting your experience. An island receptacle for a space heater is exactly what wanted it for too.
The outlets on each side of my 310RL sofa are not on the DW circuit — just checked again. I also rechecked all other 120v receptacles and they are live.🤷🏼‍♂️
The last word from Alliance is that it must be a "dead run". And that if I'm still concerned to take it to a dealer. I'm still concerned but probably won't do that.
We'll just wait and see.

George, while I would not be able to explain the rhyme or reason, did you remember to check the washer and dryer outlets in the closet and the outside receptacle, the wet bay receptacle, and the door side basement receptacle?

And the two behind the recliners? The ones under the cabinets(coffee bar, maybe even stove). Even the microwave outlet, Fire place drawer and large screen tv

Just throwing it out there, hope you get it figured out.

I will try and remember to check mine, when I reinstall my kitchen island. I had to shut off 3 breakers to kill all my power, for the floor install, but didn't pay attention to what does what.

When you turn off the DW breaker does it kill the DW circuit? Does it kill anything else? Do you have a transfer switch share box connected to the DW circuit?
The share box thing is the bizarre part of the DW circuit.

I will let you know. I know I turned off 3 breakers in the "Load Shedding panel". I have the solar package, so my understanding is that shuts off both AC and DC. I have a 370fb. I plan to get into the electrical side of things, after by carpentry adventures. If I run my Microwave, it shuts off all my GFCI outlets. which impacts my coffee maker. Luckily I have an electrical engineer in my camp group, so the fix should be easy. Electrical is not a strong talent of mine, so I have backup!!

The DW breaker does de-energize the DW Prep box I'm messing with. I just wish I could find out what else is de-energized. 🤔
I do not have a transfer switch box — that I can find at least. That'd be part of genset prep (correct?) that I do not have.

George, yes that would be part of genset prep, BUT it affects the entire service not just a branch circuit.

Do you happen to have super solar that is equipped with load shedding as Langley and RockDr mentioned ?

 

[Lantley]

"I have contacted Alliance and at first was told it goes to the fireplace and the circuit is intended to be used by either the DW or FP, one at a time."
I believe that second wire goes back to the transfer box that in my case feeds the sofa outlets. You said your sofa outlets are not on the shared circuit.
Keep in mind I am not referring to a genset transfer switch but a load sharing transfer switch that Alliance believes is sharing DW and fireplace however in my case it is not. It is sharing sofa outlets and DW.

No super solar, Just the one panel and 2x 65Ah AGM batteries. (Correction3/1/26) I had 2x FLA batteries)
Soon to be one 12V 165Ah LFP Battery.

I guess this why they don’t supply wiring diagrams.

A little passive aggressive sarcasm but you get the drift.

 

[M and E]

Microwave maybe? Have you checked that?

George, I am 99% certain I have figured out your mystery dishwasher circuit.
It might be a little know fact, but our 12 volt refrigerators are equipped with a 120VAC ice maker.

In the 310 RL, if you remove the rear panel in the bottom cabinet on the RH side of the stove you will find a hidden 120 volt outlet that the ice maker plugs into. I validated this on ours todays, however I wasn’t plugged into shore power so I didn’t validate if the dishwasher breaker killed power to the hidden outlet.

Bryan Your thinking the ice maker is being fed from the DW circuit?

Lantley, that is my current unproven theory. The dishwasher outlet has inbound and outbound wires so something else is being feed from this wiring for sure.

George had previous indicated that he tested all outlet and couldn’t find additional outlets that were killed when turning off the dishwasher breaker.

I have more work to do on reinstalling my island tomorrow, so if I have a few minutes and some energy left, I will validate or disprove my theory tomorrow with a circuit tester.

Yes but the fly in the ointment is that Alliance says the DW circuit is sharing with another outlet not feeding another outlet.
I have a sharing box attached to my DW circuit. The idea of sharing the DW circuit is just bizarre in my mind from the start.

Lantley, please explain what you mean by sharing vs feeding. Not sure I understand the difference,

My theory for example would be(example only) the the circuit starts at the breaker panel, runs to the dishwasher outlet, exits the dishwasher outlet and heads to the ice maker. This is what I mean by feeding

Your views please

 

[Lantley]

My DW circuit is wired to some sort of transfer switch that Alliance claims is designed to allow fireplace and DW to load share same circuit.
This is what George posted earlier in this thread.
MY DW circuit is wired to that box however the other output of that box feeds my sofa outlets not the fireplace.
I think the whole idea of load sharing the DW and FP is bizarre. Maybe tomorrow I will try to get some pictures of that box.

Strange that they would bury an icemaker 1230 volt outlet, where it isn't even accessible in the refrigerator box.

Here is my frig box, with only the microwave outlet (top left of picture). The microwave cord can been seen in the top section of the cabinet between frig and microwave.
