I do believe APC protects ALL incoming wires... at least on the
non-hobbyist models. My son has a rack-mounted one that includes
$100K of insurance.

View that insurance 'fine print'. So many 'exemptions'. APC specs,
as provided here, claim to protect from what? Spec numbers don't even
define many types of surges - let alone define which wires have
protection. Provided were general numbers that protect from what?
They don't even say. Provided only enough information to promote myths
among the naive.

Companies with superior reputations - that actually provide
effective solutions - include Cutler-Hammer, Square D, Leviton,
Intermatic, Siemens, GE, etc. APC and Monster Cable are not on that
list for obvious reasons.

View what another discovered when dealing with APC's warranty:
W D Loughman on 11 May 2001 in comp.os.os2.misc entitled "UPS
advice"
Don't take too seriously the implied protection of your monetary
investment when APC says: "...UPS comes with a $25,000
lifetime hardware replacement guarantee."

Described in this newsgroup late last year, their UPS failure
caused me to spend c. $1200 on replacement equipment.
After their own investigation of the damagING unit, they did
not dispute the UPS failure. However, they reimbursed me
only $200, no arguments accepted, with a required waiver =
"Sign this now", or get nothing. They use a sort of "Blue
Book" for computers, and paid only the values listed therein.
NOT replacement cost. Cover your financial losses some
other way, 'cause they sure won't. Buyer beware!

But again - conditioning from what? Radio waves from the local
station? Harmonics? Excessive power factor? Filtering for FCC
regulations because that function was missing inside a power supply?
Intermittent electricity created by a wall receptacle wired using stab
lock rather than attached by side mount screws? What does the OP want
to condition? Instead a 'magic' conditioner does everything?

Assume we need filtered 'line conditioning'. Some manufacturers
that provide serious conditioners are Zerosurge, Surgex, and
Brickwall. Why do 'real' line conditioners costs so much more? What
really does the APC do for less money?

Above functions must be in power supplies that sell on accomplishment
- not selling on price to a computer assembler who needs no electrical
knowledge to be certified.

Meanwhile, if filtering was on all wires, then the conditioner could
not be UL approved. What exactly is supposed to be accomplished -
what is missing inside that power supply?
