But you had better check your local codes. It's likely they will not
allow that setup. NEC et al are only starting points; then the local
guys get into the act and add their own idiocy, I mean, opinions of how
things should be.
KNOW BEFORE DOING is the proper mantra. Otherwise you could be doing
it more than once.
Some of the panel makers make them. Square D makes them for their Q0
panels and I think they now have them for their Homeline panels. Others
also have them.

I did this in my previous house before interlock kits were available. It
was not hard and worked very well. After checking the cost of the kits
(ridiculous!) I plan to do it again, esp. since I have two 200 Amp panels,
the kits would cost $300 to $400 depending on where you bought them.
In my situation, I do not want a gen large enough to power the whole house
so I won't use autostart anyway. I will manually turn off the HVAC brakers
before starting the gen. Then everything else in my house will have power
available, even if I cannot run it all at the same time.
I had a 6KW gen hooked up this way before. Had a 21 day power outage and
another 10+ day power outage and never a moment's trouble and no overloads
of tripped breakers occurred. Saved a lot of $$$ on fuel by not having a

I don't understand why anyone would want to select the circuits on the
generator. To me, having the whole panel on the generator would be
much easier to set up and much more flexible.
If the generator doesn't auto start, and I have never seen one that
did, then you can shed which loads you want to lock out, and the
family knows to be careful when the power is out.
The one time the daughter uses the blow dryer, and everything goes
dark would be enough reminder. The breaker lets you safely test the
I wrestled with this about a decade ago and at that time couldn't find a
clear reference in the NEC. The intent of the NEC seemed to too
establish a good single point ground at the entrance panel/meter base.
I did this with two ground rods (10 ft as I recall) at the mater
base. The run to the entrance panel is about 15 ft further inside my
basement. I have six subpanels, and none of these are grounded...all
neutrals tie back to the entrance panel.
My generator is located at the other end of my house, about 150 ft away.
I have a 10 ft ground rod at the generator to which the generator is
connected and a single #4 stranded copper wire, perhaps 200 ft long,
buried along the perimeter of the basement that bonds this ground rod to
the two ground rods at the meter base. At the time I did this I felt
that I was in compliance with the NEC (although today I can't cite a
