Breaker panel with main fuses?

But not foolproof, is it.

Nothing is foolproof. Fools can be very resourceful. What's your point?

You could always do that in a separate box. The problem with using that to isolate yourself from the grid INSTEAD of a transfer switch is that it's still possible for a bone-head to forget that step, and fire up the generator with the main still in. The point of a transfer switch is that, barring a strange mechanical failure, it's not possible to connect the generator to the grid, it's either/or.

Which is more likely to get it wrong, the person running the system, or the transfer switch?

Geeezzzus, just get a transfer switch! Why not do something correct (right) from the git go? Why futz around with it? WHY WHY WHY???

Also not legal. Pop

That a transfer panel needs to be foolproof, because lives depend on it.

Reasonably priced transfer panels exist, they use a mechanical interlock, that makes the transfer foolproof, in that you can not forget to disconnect the mains.

Yes, better fools are being invented all the time, thus the usage of a method that makes it impossible to screw up.

Cuz then we wouldn't have anything to talk about...

According to zxcvbob :

A positive mechanical disconnect, but not a foolproof _transfer_ mechanism.

The code insists on it being impossible to reverse energize the grid from the generator and vice-versa.
