The function of a surge protection device is to prevent a sudden Surge of Voltage from damaging your electronics by providing a path of least resistance to ground.. a protection against lightning strikes to overhead electrical lines and or from bad earth rods (which picks from impact zones and carries the voltage surges to your box) .
Only if this is the case then you can install it anywhere from your kwh meter cables to your distribution box.. A common practice is to install inside the DB but its not the only way to have it installed..
You can have it installed in its own enclosure after the kwh meter at any point before the DB (thus the equipment to be protected)... connect all phase/neutral cables to the SPD and connect SPD to a known good ground. (Ground rod reading below One Ohm)..
Thanks! Richard. I will ask electrician to install the SPD for me and help to check my house has good grounding or not
(I don't think I can install it myself, you are good and able to fix it yourself
)
Btw, I snapped a picture when my contract installing the ground rob in front of the garden, the copper rod was about 10 feet long, with diameter of 1.0 - 1.5 cm.
