Being from Florida,
Generators come to mind,  I am building an apartment in a hangar.
Item #1 for me  was a whole house generator transfer switch installed in 
original construction.
This is with a SquareD Combination Utility Service Box ( incorrect name 
probably )
It has a hole for the Meter and 8 Breakers, two of which will be used 
for the generator hookup.
These two are interlocked with the MAINS breaker and function as the 
manual transfer switch.
The price of the interlock mod kit is less than $50.00 and you are set.  
Then the MAINS to onto the
normal interior breaker panel.  Even if you don't have a gen or don't 
plan on one, it is cheap now and up to Thousands$$$  later if you change 
your mind.


Cheers,
Kevin Hanna
