Looking to clarify some points installing a Leviton 51110 whole
house surge protector from Home Depot.

The surge protector has four leads - two black, one green, one white.

1. From what I understand the blacks need to go to adjacent 20 amp
breakers, doesn't matter which goes to which. There aren't two
adjacent 20's on my board so I gather 2 more need to be installed?


It would be very unusal to have an extra breaker there,
waiting for someone to come along and need it.



1b. - If 2 more breakers need to be installed, the available spots are
below the already installed breakers. Shouldn't they be as close as
possible to the top of the stack of breakers so any surge hits the
protector before hitting the rest of the breakers or not necessarily?


For all reasonable purposes it doesn't matter where on
the panel it's connected





2. The instructions specify the white line going to the neutral bus,
the green going to the ground bus. However, the schematic seems to
show the green and white going to a common ground.

On my box, I've id'd "A" as the neutral bus - the one with the white
wires going to it, "B" as the ground bus. Is this correct?


How would we know without seeing it?


Anyone have experience with this particular unit?

No experience is required with that unit.
The principles and operation are the same
