Been doing it for years. The outside transfer switch just makes it more
convenient. Actually, my point was that there are many devices
available today that weren't around years ago. I had never heard of
an outside transfer switch like the one we are installing. My
son-in-law, being current on this stuff suggested it.

You're talking about something like this, right?

I wonder how much an electrician would charge to install one. Might be a nice Christmas present for
the kids.

Installing the switch is not the expensive part. It is swinging over
the 6 (or more) circuits you want to transfer. Your mileage will
certainly vary on that one depending on where you want the generator
and where the panel is.
Also be aware generators may be putting out 115 volts and not 120 so
voltage drop can be an issue. That feeder from the generator may have
to be up sized if it is very long. I know it was a problem for my. The
fridge in the kitchen was only seeing 106-108v on start up.
I now have one of these for it. (a gift from Henk, my dutch friend)

It lets you adjust the voltage up or down.



Greg, I think you are making this far more complicated than it really
is. The unit John found has a 10 foot long whip with 10 awg wires for
each circuit to be transferred. More than enough for typical household
circuits.

The idea is to mount the transfer box as close to the indoor power panel
as possible. If that can't be done, then another method should be used.

I had a voltage drop problem in Florida when I ran power down to a slab
that I put in for the RV we had at the time. The slab was about 75 feet
or so from the house panel. I used 6 awg wire but the voltage
at the RV drooped to as low as 104 volts sometimes mainly because the
whole service to the community drooped at times to under 115 volts. I
got a Hughes buck/boost autotransformer that cured that problem.

How is my variac "too complicated" It is essentially what your buck
boost transformer does, it was free and it is adjustable.
The only thing I had a problem with was the fridge in the kitchen and
that is because it is a long way from the generator. (Using existing
house wiring)
