hints
As discussed earlier,
there are several locations in your power system where you can connect
(install) a surge protector, depending on the type of protection you desire and
your inclination toward do-it-yourself or hire someone. These possible
locations are shown in the sketch below, with appropriate hints on how to go
about the installation.
A very important point to keep in mind is that your
surge protector will work by diverting the surges to ground (see "What's in a name") The best surge protector in the world
can be useless if grounding is not done properly. 
- Meter-base adapter
This is the most involved installation, requiring cooperation of
the power company if they allow it to be done by a licensed electrician. They
might also do it as part of their own program *.
- Service panel, upstream
Also a job for a licensed electrician since the power cannot be
turned off on this side of the service panel *
**.
- Service (breaker) panel, snap-in
First opportunity as a do-it-yourself
project, provided that the hardware is compatible and that local authorities
allow the owner to do it.
- Service panel, downstream
Another possibility for do-it-yourself. The protector should be
connected on the load side of a pair of dedicated (spare) breakers in the panel
**.
- Receptacle, built-in
Provides same protection as a simple plug-in protector, but stays
in place and cannot easily be moved to another receptacle, should that become
desirable.
- Plug-in (with cord or directly into receptacle)
The easiest of all for anyone to do. The only
question is "Which to choose ?"; have given you some
elements for making that choice.
* It would be a good
idea, to ensure compatibility, to ask the electrician to look into the ratings
of the device and the power system available fault current.
** The protector should
be located close to the service panel (less than about 30 cm or one foot),
otherwise the voltage-limiting effect will be degraded.
