re: Transfer switch for generator
Posted on 6/28/23 at 8:07 am to BatonRougeBuckeye

I have a 6500 generator with only a 30 amp locking receptacle. The house I just bought has a 50 amp setup to hook up a generator. Is it as easy as a 30 to 50 connector to utilize this setup, or am I looking at a new generator purchase with a 50 or changing the connections on the house and breaker to 30?

Should be no issue to have the 30 to 50 connector. I believe that's how my generator is set up. Even though it's 11kw, it's only a 30 amp output. Never had an issue.

My 6250 watt generator has 30 amp outputs, but I plan on getting a 50 amp outlet for the transfer switch. I can use my 30 to 50 amp RV dogbone for this. I want a 50 amp in case I upgrade to a 50 amp generator.
Will a 10 circuit transfer switch be the same for a 30 amp or 50 amp?

damn baw, is your house three phase running at 360,000V Line-Line (208,000V Line-Ground)?

Yes - I don't want to share any power. It is corrected in my post.

Another electrical contractor came by and he thinks he could put an interlock at the main breaker (disconnect) that is outside of my house. I would plug in my generator in at this location. There is another disconnect at the meter location at the street. I guess if this works I would turn off what breakers I don't want at the panel in the garage.
Is this correct?

Yes - this is how my system is set up, and it works fine.
In my case I needed to upgrade my main outside breaker panel (disconnect) to accommodate an interlock kit but other than the added expense that worked out OK as it provides me some additional outside circuits should I want to run electrical service to areas of the backyard.

That would be a plus being I could use some electrical outlets at the back of my house.

The cost for an interlock switch is over $1,000 less than the quote for a transfer switch.

It could be, it's hard to say without seeing the service.

I would do a lockout kit and 30A plug instead of a transfer switch, then you could pick what circuits you want power to.

Interlock kits are easy DIY jobs, but better make sure to have your ducks in a row so you don’t burn something up.
I’ve not seen anything under 12k watts that can do 50 amps. It may have that connection but it can’t push it. Save some money and get you a 2 pole 30amp breaker and 10/3 romex. I do have mine running thru the 50A plug though. Beefier connection.
If you’re going to plug your 30 amp plug into a 50 amp inlet. Better make sure it’s got the same number of wires. Some 30A generators are only 3 wires (incl ground)
There are tons of step by step videos on YouTube. Makes it an easy DIY for the handy folks.

5700kw is a big arse generator, how big is your house? How did something that big not come with a transfer switch? I have 65kw that runs my house and I thought that was big.

Random bump
I'm wanting to install a 50amp inlet box on the house so I can run a cord from generator to it. Only issue I have, is I can't find the "Main Breaker Box". Been in the house a little over a year and the only box besides the one inside that separates the different parts of the house, is one outside that in sharpie, has written "subpanel", and has my AC units and my garage powered. I can't hook to subpanel correct? If not, what would be my best option to get generator power to my house?

I had a similar issue. My sub panel is inside the house, the main panel is outside and has AC service breaker and main power breaker. My electrician setup another panel next to the main, moved the main breaker over and added a breaker for the generator with a lockout. Cost me about $900 for everything.

Does that outside “sub-panel” with breakers for your HVAC and garage also have a 200 amp breaker? If so, that breaker box would be the “Main”; that would shut power off to the house. If not, does the breaker panel inside the house have a 200 amp breaker placed above all the other circuit breakers, if so, that would be “Main” breaker box that would shut power off to the entire house.
When you must determine if the panel with the “Main” 200 amp breaker can accommodate an interlock kit.
In my case, my “Main” panel, outside next to the utility meter could not accommodate an interlock kit, so I needed to upgrade outside main panel to install an interlock and a portable generator plug outlet. I had an electrician do this. The cost was $1K, which included all parts and labor, and the portable generator outlet electrical cord. This was last Fall.

This is your main. As long as there are less than six breakers in that panel, that will be your main panel. Its a little more complicated for you.

This is what I am having done next week.
