Default lightning strikes



The idea that a surge protector csn protect againt a lightning strike
is one of those misunderstandings the manufactureres only encourage.
What they really do is introduce a fire risk and take your money.
Agreed, and it's not just catastrophic faliure of the sacrafisial MOVs

Case in point; look at this Belkin branded power-strip that failed after
a short time

This is rated for the full 13A continuous load and note how the
connections to the bus-bars are properly ferruled and spot-welded,
but, oh dear, look at the intervianing surge protection board,
4 blobs of finest lead-free!!
These solder blobs are supposed to pass 13A continually?
I_don't_think_so.
Fortunately the resulting dry-joint went
totally open-circuit without too much arcing and sparking.

Who agrees that a better arrangement would for the incoming
cable to be ferruled and spot welded onto the bus-bar and
the PCB to be connected to the bus-bars at a different
point?
