Since my 5KW gasoline generator is manual start only, I did not require an
automatic transfer switch. I also elected to go without the manual transfer
switch either and just use the 200A main breaker for this function (the
breaker needs to be switched off in case commercial power is restored while
the generator is operating). In my case, I ran a separate 30A 208VAC
breakered circuit to my garage. I can use this circuit for HD tools, but it
also provides me the ability to "backfeed" the main electrical panel so I
can distribute the available power to any of the house's 120VAC circuits
that I want (refrigerators, sump pump, gas furnace pilot & blower, etc.)

I've created a simple wiring diagram and specific step-by-step instructions
in case I am not around and the wife or older kids need to get this working
in my absence. If interested in a copy, send me email.

I am looking for advice on the easiest way to wire up a modified
electrical distribution panel here at home, to allow a generator to be
fired up and take over power supply to the house during one of our fairly
frequent mains failures.

In the States, these devices are called "transfer switches" and a
Google search will show many designs. They are available in manual or
automatic versions, with the manual being cheaper. They are basically
a large DPDT switch. The automatic versions include power sensing and
delay hold functions.
