This panel has a transfer switch for each circuit (top switches). It comes with a pre wired pig tail for the circuits and the utility feed (240).

Typically you move your emergency circuits from the main or sub panel to the generator panel. (j box on the right is the splice) The circuit is still fed from the original breaker, hits the transfer switch in the generator panel and then goes back to the original load via the bottom breakers.

The generator only feeds this panel and has no way back to the home’s main panel. The transfer switches only allow GEN/OFF/Utility and never a combination of the 3.

It eliminates the need to have to worry about shutting down unnecessary circuits (A/C condenser/pool/etc). Which for those that don’t know is very important when using a portable generator. Too much load and the generator breaker will continually trip while your wife and baby are yelling

Edit: attaching reliance’s wiring diagram for reference.

Tried your attachment, didn't work for me. I was more curious just how many wires were in that 3/4 or 1" between the gen panel and J-box 😳 I've never seen a transfer panel like that one, pretty cool. Although a tad confused when I noticed two - 2 pole transfers on the left, but only one 2 pole breaker below it.

Maybe this will work. It’s a lot of wires lol

That second transfer switch is for the 2 factory 240 circuits. Looks like they only needed 1 and just used the other as single circuits (tied together by the 2 pole transfer switch).

Shit, wish I knew you were a dealer. I bought a Generac 15kw ecogen from Norwall a couple months ago.

Thanks for that attachment, explains a lot. One glaring reality is, you damn well best be using a 240 V generator and NOT two 120V generator receptacles with a "Y" pigtail or you'll be frying that SINGLE neutral wire. I was picturing a separate neutral per circuit --- so even more conductors in that conduit --- which now I see is a pre-wired pigtail.

Because my main panel only contains large 240V circuits, like solar, AC's, Kitchen Cooking and three sub-panel feeders, it's a bit more complicated ----- unless I were to use a single transfer "All or nothing" switch. With maybe one or two short outages a year, if even that, it's hard to commit financial resources to backup power, other than a genny and a few extension cords.

Ok got it -

You pre decided what you weren't ever going to run off your genset and removed the ability to do so regardless of you managing the load. (the bulk of your 240 gear)

My LA house is set up similarly with 120 only to the pony panel.

I'm a bit surprised the 3 way switch is kosher - but its really cool.

Oh I know about overloads....

Been installing this one over the last couple weeks in my free time. Almost ready to fire it up. 35KW with 400A ATS. 195Gallon Base Tank.

I love that. You can power up the entire city of Burbank.

Just a matter of time until the Democrats come after all of us for this.
Permits, restrictions, regulations, taxes and fees.

Im not as far along as you are.

I've just got the concrete base in for a 20KW Kohler running off natural gas.

Needed to run central AC and a well pump.

Had to permit it because I needed to upsize the meter - it was 20 cubic feet short of the number - F@*$*%((#*@@#$$!!!

Most of the perm generac's Ive seen in the 20K range have really low valve lash adjustment intervals. Not sure about that model.

Ya, I did a new 400A service as well. I live in a small town though so permits go through real easy.

We are so restricted in Norther Cal (Menlo Park) that they would not allow generator or stored fuel for a critical office we have there. Problem is we lose power 4 to 5 times a year. We got around it by buying a 24' Penske truck and mounting the generator and fuel tanks in there, power drops, we just back the truck up to the side of the building and plug into a special harness, boom, we have power. The city keeps trying to fight us, but we keep beating them at this game.

My business partner put a playhouse in his back yard to hide his generator, it's all sound proof, looks legit. He just needs to keep the lights to a minimum when power is out as not to tip anyone off. California sucks.

Supposed to be low service. It's one they market to off-grid setups like ours so there's some features we like. Our lithium batteries charge so fast I'll be surprised if this thing ever sees 100 hours in my lifetime but it'll nice having a fully automated system.

Pretty sweet setup for that low usage - you got a sister?

Im already at 100 hours in the last 30 days.

Not for you but this just stepping into this -

Most often ignored piece of small genset maintenance is valve lash.
Hard to find anyone thats ever done much less knows their own intervals.
You starting running some hours under a load and they will start moving.

Contrary to popular thought they lash doenst grow on these it shrinks and the valve pounds into the head then it stops closing then it burns.

So kind of off subject a little bit.

I have 2 of these Cat units. They just came out in the spring I believe and I got the first one Electric Generators Direct sold. I bought it to power the AC on my dirtbike trailer and it works great for that. The last hurricane that hit a couple weeks ago knocked my power out for a day or so and I used it run our fridge/freezers/hot water/stove (LP)/internet. Worked great for that.

One of my wife coworkers called and asked if we had a generator the could borrow and I told them I had a NIB briggs & stratton Q6500 that I would sell for less than I paid for it. They were going to come and get it and their power turned back on before they left the house so they decided not to buy it (which is fine by me) but asked what they should buy to power a few items around the house. I was going to point them to the CAT unit but found it discontinued on all of the websites which I found to be odd. I called CAT and they told me they quit making small generators which kinda caught me off guard. Has anyone else heard this.

They make a plug to run the 2 units in paralell that I was going to buy at some point but guess now I'm SOL. They told me to go to a local CAT dealer to see what I could find out.

I have the 3000 wen unit, 890+ hours on it. Sips fuel, and pretty quiet, and under a doghouse. Nearly maintenance free, only replaced the fuel line, started seeping at the shut-off valve.

Ya want clean power 1.5% or less distortion.

Those non-inverter portables can be as much as 30% distortion.
Computers and TV's can't jive with that nor plug-in Hybrids/elect cars..

Natural gas powered Honda 7000's are hard to find. Easy as all get out to plug and play and be good to go. Expensive too. Just plug the BBQ's NG gas line into them and away ya go.

Good to know, thanks. The Wen has more watts compared to the HF and already has the RV plug and ability to run the gas out of the card by simply turning the dial to off. Oh, and if you do buy one, you have to run it more than 2 hours for the hour meter to not reset. I did my first oil change at 1 hour and could not figure out why it went back to zero. I called customer service to get the info to run it for 2.5 hours to make the timer hold its readout.
