Generator Selection?

[grsthegreat]

I like that punches don't make shaving like holesaws do, but you still need to drill a pilot hole.

grsthegreat,

>> is there any warranty related reason I cannot remove the entire backplane with all components intact so I can drill/punch holes for conduit without risking getting shavings in the components? Looks like the four corner nuts and ground cable will free it all.

>> Is there any reason I cannot, or should not mount this to Super Strut used as stanchions embedded in concrete? Wiring would then be in either rigid or sealtight. My exterior wall construction would make wall mounting complicated.

i always remove guts Before drilling. Mind you i have a hydraulic punch kit similar to this





that punches holes from 3/4” to 4”. But still have to drill pilot hole. But unless you have 1500+ to waste...
Go hole saw.

No problem with mounting on strut. I mount to strut all the time.

Personally, if your never have use for 1-1/4” hole later on, just get a hole saw. Make sure you size it to the thread.....not 1-1/4” hole.

Im not sure how accurate the following chart is, so measure actual fitting.

For smaller holes step drills are very useful and quick for small conduit and pilots

With split system heat pumps i would not go below the 16 kw current line, which will soon be 18kw.

a 13 (soon to be 14kw) would probably work.

Do we know if either or both of those are compatible with my RXSW100A3 Transfer switch? I don't want to make any marks on it until I know.

They will all work. Your switch will work with any Generac generator. It will now work with other brands.

The Generac ATS is a dumb switch, that is the reason it is the cheapest. It has no line monitoring capabilities, although it does need line power to close the switch. It can do load shedding and staging. It is easily adapted to line monitoring controllers like the deepsea 7200. You feed 12vdc and then ground one lug to activate and if generator power is up it will transfer.

It's not exactly dumb in that it has utility power monitoring to an extent once connected to the generator controller. There are sensors in it that the generator controller needs. But no, it will not transfer automatically by itself.


I keep looking at the pictures though and noticing things missing or different from the manuals and diagrams. Simple things like labels, such as the E1/E2 and T1/T2 connections. Makes me wonder if they're rushing things through and the QC is slipping.

I'm guessing you meant a 't' there?


Do we have any hints on pricing of the 14 and 18 yet?

It has no sensors in it for line monitoring, it just passes 110V up to the Generator Controller which has the logic and programming. It does have loading shedding circuits that trip by frequency drop that indicates too much current draw. It runs via one 12voltDc double pole relay. The power to drive solenoids comes from either gen or line. So when controller tells it to transfer to gen, the relay connects the solenoids to gen power, another switch turns the solenoid off once it completes the transfer. It is nothing more than relays and mechanical switches.

The transfer switch has gone through several model updates, but is functional the same. They just keep finding ways to lower the cost.

You can use the load shedding circuits regardless if it used on Generac system. You just feed the low voltage from the thermostat into it, or any device you want to control, even a hot water heater by adding a relay in it. However it is mainly designed to stage things AC's with large start loads.

Yout right.... i have fat fingers. It will not work with with other brands. But some people have modified it to work with other brand generators, but you run the risk of problems modifying them. Theres a company called PSPPRODUCTS that sells some modification parts and load shedding options.

 

[RoyKing]

It doesn't need to be modified, only takes two wires 12vdc and ground.

Here the pics of a 36kva I designed, this is so quiet you can talk standing right next to it, only pain was getting it hurricane certified, as if that thing was going blow away.
