Need generator planning help

A new level

Active member
Power at my new house isn’t exactly reliable especially with all the crazy storms we’ve been getting. So I’m starting to plan out what I want to do for a generator. Long term goal is to get one of those hard wired big bastards but my wallet has other ideas. For now I’m thinking going with the Predator super quiet inverter 9500.

The 67 dB is very nice especially seeing it will be near the bedroom windows. This will also be nice once I have a camper. It will run everything I can throw at it including a welder.
Supposedly it will do 9500W peak but with my limited understanding of how electricity works won’t anything over 7,200w pop the 30 amp breaker? It would need to be a 40 amp correct?

Next, my house has the fanciest back feed setup I’ve ever seen. Currently has a 20amp breaker with a 10/4 cable running outside

To a fuse box with 30 amp fuses

Then goes to a box in front of house with plug.

I’m going to change plug so I can use this for my welder when power is on. Figuring I’ll replace breaker with a 30amp.

Next is the 3 ton, 36,000 btu A/C heat pump. I’m thinking a micro-air easy start 368 should do the trick unless someone has a better idea?

Assuming I’m totally screwed for hot water with the amount of juice my tankless pulls.

(And yes my wife likes to burn a layer of skin off when taking showers hahaha)

In my rental I’d play Apollo 13 with the amount of watts I was getting. Turn whole house off, turn on water heater till it got hot, switch to well pump and a few lights on, take quick shower, turn pump off, turn everything else back on. Thinking I might get a small hot water tank as a backup so I can do this unless someone has a better idea.

This is as far as I’ve gotten in my research. I’m sure more will get dug up as a Jason this.

You need a manual breaker interlock or a real generator panel.

You'll need to shuffle things around a bit to do it properly.    If you want to keep it hilljack change the  20 to a 30 with #10 wire.

9500 is max. covers inrush for large items like motors starting a breaker will hold well over its rating for a very short amount of time to allow it. 

Looks like a fairly well done harry home owner install
 
That’s what I was thinking. Short term swap to a 30amp. Eventually make a proper generator panel and keep the setup for welder until I get proper garage.
 
Make sure the "plug" on the disconnect is flipped over to the off position so your suicide cord isn't all ouchie on the end

Fist thing I did was turn breaker off and flip plug!
 
That generator should be adequate for your needs.  I run my whole house (minus hot water heater) with my Generac 6500 (8000 starting watts)- that includes a 1HP well pump, washer/dryer (propane dryer), dishwasher - never tried hot water, tank stays hot for days.  I used to have a 3O amp circuit / outlet I used to back feed it through.  A few years ago I decided to ditch the suicide cord and install a proper generator input and switch...

If I have A/C (Happy wife) and wifi (Happy kid) don’t care about much else other than maybe the refrigerator (cold beer happy me)
 
My little 5500 powers 2 full size fridge freezers and my chest freezer, as well as my wifi, phone chargers, and a few lights. No well pump and my hot water is natural gas. Heat is just a fan for the forced hot air. I give up my dryer, dehumidifier, stove/oven, central air, and obviously the garage tools that don’t run on a battery.

Biggest thing for me was charging phones and keeping the fridges cold. And if I have wifi I can work from home still if needed.

Definitely looks like a decently done home setup. If it’s already #10 wire, swap out for a 30 amp. My breaker panel has a physical interlock on the panel. If you can rearrange your breakers to put the generator in the top corner, a mechanical lockout would be pretty easy to install.

I see, ya don't have one of them fancy electronic units...
I fix fancy shit for a living.  Keep the shit at home as basic as possible so it breaks less
