[C38] Invertors

I have enclosed a simple diagram of how to cheaply connect gensets or
inverters to your 120v system. This is a foolproof and easy way to do it.
If your combined loads exceed the rating of a simple 3 way light switch,
you can make multiple switches in parallel with each switch operating a
single load. A good heavy duty 3 way light switch will safely carry 15
amps which is plenty to operate my refrigerator and microwave at the same
time but it's easy to add another switch if needed.
I have used this technique to hook up gensets to houses for over 40 yrs
and never had a problem. My last house had 12 switches, each operating a
single load. In a power outage, we had just about every light available.
My using multiple switches, it stages the load unlike a single heavy duty
transfer switch which can stall a genset when too much load is applied all
at once. With multiple switches, the generator can keep adding fuel as
more load is applied allowing a rather small genset carry a pretty hefty
load without harm. The same staging technique will work on our boats also
with as few as two switches which is a consideration if you ever plan to
use this technique with a genset on board.
