Last year we bought a generator. We did not get a transfer switch but

asking ... for a 5000 horsepower generator - what should the average
price be. We only expect to have about six outlets (120). And what
should we expect to pay to install it - garage is concrete block so it
would have to be mounted on the wall with screws. Thanks. I am in
Tampa Bay area.
I don't know if anyone else mentioned manually operated
double pole double throw safety switches. I've installed
several of them over the years as an economical way to
transfer power from the power company feed to a generator.

Does a transfer switch switch the neutral or just the two hots? In the
commercail 3 phase units we uses at work the nuetral is switched. I
was wondering if this was true for residential units also.

The switches I've installed in homes have only switched the
two hot wires even the automatic variety. I don't remember
if the Onan three phase units I installed switched the neutral.
Even the Kohler 40kw unit I installed didn't switch the neutral.
I've installed Generac generators in 8 to 20kw sizes and none
of them switched the neutral.
