[aprssig] Shack backup power

[DALE]

In my area if they hear a generator running they come and make you shut it down.
They are a little paranoid.
If a generator is running and feeding the grid all the air conditioners and
other stuff hooked up to the same transformer is goingto short out the generator and trip the breakers.
They also work on the line as it is hot any way.
Most dead short the line when it is being worked on.
very unlikely a generator is going to kill a lineman.
I use a suicide cord to hook mine up after I have tripped all breakers.
One main breaker kill the whole house.
I am thinking of putting in a transfer switch, but it is $200.00 just for the panel.
We get very few power failures any more.
When I did not have a generator we had a lot of them.
It is amazing what a back up generator can to to improve the grid reliability.
Worth Avery penny I spent and the generator is just like new and converted to propane.

If you have a properly wired transfer switch, it would be impossible
to feed to power out to the line. The transfer switch is like a DPDT
switch. Your panel is either connected to the line or your generator. 
The generator is never connected to the line.

In the case of generator haywired into the house wiring, there is a very
real possibility of human error and feeding power out to the line.

Grid-tie inverters are safe because they shut down if they don't see 
power coming from the line.
